• Can I use Slime Tire Sealant in a tire with an inner tube?

    This formula has large particles that may not seal smaller punctures that occur on an inner tube. We do not recommend or guarantee performance of the product in this application.

  • Can I use Slime Tube Sealant in a Tubeless Tire?

    No. This formula does not contain the rust and corrosion inhibitors necessary to protect a wheel. We do not recommend or guarantee performance of the product in this application.

  • How do I install a tube into my tubeless tire as a repair?

    1. If you elect to do it yourself, you will first need to purchase a Slime tube that fits your tire. Start the installation process by cutting out the existing tire valve. Break the tire off the bead on the “valve –side” of the tire pulling the tire far enough off the rim to allow you to feed the tube in. A couple of flat head screw drivers can come in handy here. Before installing the tube, take a rag and wipe the inner casing of the tire to ensure there are no thorns, burrs or other objects protruding through the tire that might puncture the new tube.
    2. As you feed the tube into the tire make sure there are no kinks. Feed the valve stem through the existing valve opening in the tire. Once the tube has been fed into the tire and the stem is in position<,> you will need a small set of vice grips to clamp onto the valve and hold it in position so it doesn’t’ fall back into the wheel. At this point you might want to inflate the tube slightly before you begin to set the tire back on the rim. Once the tire is on the rim, continue inflating the tire to the correct psi.
    3. Slime can escape up through the valve stem when the tire is checked for air pressure or inflated. Always rotate the tire, when possible, so the valve stem is in the 10 – 2 o’clock position.   This enables the sealant to flow away from the valve preventing the product from blowing up through the valve where it might clog the valve, air pressure gauge or air source.
  • I have a cut from glass in my bike tire. Will Slime work to repair it?

    No. Small punctures are an easy fix, but large gashes from glass, metal or a tear are not easy to repair. Any constant bending and flexing of the tire over rough and uneven surfaces will make it much harder for Slime to create and maintain a permanent seal.

  • I have tubular (sew-up) tires on my bike. Can I use Slime?

    Yes, look for our 8oz Tube Sealant with the red label. This is the perfect size for two bike tires.

Emergency / Help
  • I installed Slime recently and it failed to prevent my tire from going flat. Why didn’t it work?

    If you installed Slime to repair an existing puncture, it may not have adequately sealed on the first attempt. We recommend checking the tire for puncturing objects, removing any if found, re-inflating the tire and immediately rotating it. This forces the sealant to flow around the inner tube or tire allowing it to locate and repair the puncture. Slime is not guaranteed to seal gashes from glass or metal, bead leaks, sidewall punctures or pinch flats. Be sure to check your valve to ensure air loss is not occurring at this source.

  • What do I do if Slime is swallowed or inhaled?

    Seek medical assistance immediately.

  • What is the warranty for Slime brand products?

    Tire inflators and air pressure gauges have a one year warranty from date of purchase. Your warranty will be void if you abuse, unsafely use, improperly use, or use in any manner that is not consistent with the operating instructions. Slime is backed by both a satisfaction guarantee and a limited warranty. If you are dissatisfied, return with original proof of purchase to the place of purchase for a full refund or product replacement.

  • What should I do if I get Slime in my eyes?

    Thoroughly flush the eyes with cool clean water until you feel the product has been properly flushed out. If the eyes appear irritated after flush, seek medical assistance immediately.

  • What should I do if Slime is spilled?

    Because Slime is non-toxic, the cleanup is easy. You can clean it off of any surface with a rag or a towel. We suggest you follow up with whatever cleaning product you would normally use to clean that particular surface to ensure a complete clean. We also recommend properly disposing the excess Slime and saturated rags after cleanup.

  • Will Slime void my tire warranty?

    Warranties vary by tire manufacturer. Contact your tire manufacturer for specific details.

General Information
  • Can a Slime treated tire be professionally repaired?

    Yes. Passenger vehicle tires treated with Slime should be professionally repaired with an RMA approved patch/plug at your earliest convenience.  Inform the shop technician that Slime is in the tire.

  • Can Slime be added to a tire to balance it?

    No. We do not recommend using Slime for this purpose.

  • How does Slime work?

    Slime coats the inside of the tire within the tread area, allowing the product to seal tread area punctures. When the tire is punctured, the escaping air carries the sealant to the puncture. The liquid portion of the sealant escapes and the fibers and binders build-up and intertwine to form a flexible plug. This will allow the product to instantly seal any puncture that may occur.

  • How much Slime do I need to install?

    The following provides general application information. Be sure to use the formula that is correct for your tire type (either tubed or tubeless)

    Bike = 4 ounces per tire

    Motorcycle = 8 ounces per tire

    Wheelbarrow = 8 ounces per tire

    **ATV = 24 to 32 ounces per tire

    Trailer tires =12 ounces per tire

    ** It is important to make the following calculation for LARGE tires.

    1)    Take physical measurement of the tire’s WIDTH and HEIGHT in inches

    -          For high speed tires ( 45 mph or over) multiply W x h x .065 = __ ounces

    -          For low speed tires ( 45mph or less) multiply W x H = __ ounces

  • I have a puncture in an inflatable (mattress, dingy, Zodiac, ball, etc.). Will Slime work to patch it?

    We do not recommend nor guarantee our product for this application. Installing sealant into a wide/deep chamber without having any way to direct the sealant to the affected area would render it useless.

  • I installed an aerosol flat repair product, but it didn’t work. Can I now install Slime?

    No. We do not recommend or guarantee our product’s performance when used in conjunction with another product.

  • I would like to purchase your product, do you sell direct?

    We currently do not sell directly from our website. We do supply our line of products to a broad range of distributors and retailers in just about every industry (bicycle, motorcycle, ATV, lawn and garden, hardware, automotive, and industrial.) .

  • Is Slime drain safe?

    Please verify local waste disposal requirements. Requirements vary by county.

  • Is Slime TPMS safe?

    Yes, Slime makes a TPMS safe formula for cars and trucks with Tire Pressure Monitoring Systems (TPMS). Look for the yellow bottle and the TPMS Safe icon. Many of Slime’s Spair kits also feature TPMS Safe Sealant. If your vehicle has TPMS, try the Smart Spair or Safety Spair from Slime. 

  • I’ve heard Slime will ruin my rims, is that true?

    Our Slime Sealant for tubeless tires is formulated with rust and corrosion inhibitors as well as a pH buffer making the product more alkaline. All of these ingredients work to protect the integrity of your rim. It is important to note there are factors which can allow damage to occur in spite of this. If you want to err on the side of caution, you can use Slime as a roadside repair. All you need is Slime and an air compressor! Slime can have an adverse effect on certain types of aluminum rims. Because alloys differ, it is difficult to predict how Slime will react with your rims specifically. Over the years, though, we have found that older rims are more susceptible to damage from Slime. Make sure that, if you have tubeless tires, you are using our tubeless formula. Our inner tube formula does not contain rust and corrosion inhibitors. Do not leave Slime inside your tires for more than 2 years. After that time, we cannot guarantee the integrity of your rims. If pre-existing damage is present, we do not recommend using Slime.

  • Regarding tire Pressure, what is PSI, BAR, and kPa?

    Vehicle tire gauges, and many other types of pressure gauges are zero-referenced to atmospheric pressure, which means that they measure the pressure above atmospheric pressure which is around 1 BAR. The following key terms may be beneficial when dealing with your gauge.

    1.  PSI (pounds per square inch) standard tire pressure reading in the USA
    2. KPA Kilopascal – A unit of pressure. 1 kPa is approximately the pressure exerted by a 10-g mass resting on a 1-cm2 area. 101.3 kPa = 1 atm. kPA is used as a unit of measure in Europe and other areas that use the metric system.

    BAR The BAR is a unit of pressure defined as 100 Kilopascals. It is about equal to the atmospheric pressure on Earth at sea level. 1 bar = 100 kPa (kilopascals) per square centimeter. 1 Bar = 14.50 PSI.  BAR is used as a unit of measure in Europe and other areas that use the metric system.

  • What happens to Slime after 2 years?

    Slime is a liquid that may dry out over long periods of time. The rust and corrosion inhibitors in the sealant also break down over time. For maximum puncture protection and optimal performance, we recommended that Slime be replaced after 2 years. For most tires, this will also be the time period for replacement due to wear and tear.

  • What is a Valve Core?

    When you look at the tire valve you will see a metal cylinder in the very center. This is the valve core. To install Slime, use the black valve core removal tool on the cap of the bottle to slowly twist the core counter-clockwise. Allow the air to slowly escape before removing the core completely. After installing Slime, replace the valve core and re-inflate the tire.

  • What is Fibro-Seal Technology?

    Fibro-Seal Technology is the feature that forms a flexible plug to seal punctures. Slime’s fibers, binders and clotting agents are carried by the liquid portion of the sealant to the puncture where these Fibro-Seal particles build-up to form a long-lasting flexible plug.

  • What is the shelf life of Slime?

    When Slime is stored in its original packaging and placed in a cool dry place it will last for 4 years. Once in the tire, Slime will remain active for another 2 years.

  • What type of punctures and cuts will Slime seal?

    Slime has different formulas, each with different sealing capabilities. Slime Tire Sealant will seal punctures up to ¼” (6mm), and Slime Tube Sealant will seal punctures up to 1/8” (3mm). In both cases, the puncture must occur in the tread area of the tire since Slime cannot reach or seal punctures outside of the tread area. Slime will not seal bead leaks or large punctures.

  • What’s the difference between a Presta and Schrader valve?

    Schrader is seen more as a standard “car-type” valve while the Presta valve is tapered and often found on high-end performance bicycles.

  • What’s the difference between Slime liquid sealants and aerosol type repair products?

    Slime liquid sealant is non-toxic, free of carcinogens, cleans up with water and does not contain propellants. An alternate air source is required to inflate tire after installation. Aerosol repairs provide minimal inflation, delivering only enough air to lift the rim off the ground and can only be used once.

  • When Slime repairs a puncture does the sealant actually harden?

    No. The Slime is actually a delivery system for fibers, rubber particles and other sealing agents. As the liquid gets forced out through the puncture, it carries along with it the larger puncture repairing ingredients which pack into and seal the hole, preventing air loss. The green dot that may be visible on the outside of your tire may not harden, but may congeal, which results in a flexible seal.

  • Why do you offer different sealant formulations?

    Slime offers specific formulas to meet different needs.

    1. Our yellow label TPMS Safe Tire Sealant is designed for use on vehicles with Tire Pressure Monitoring Systems (TPMS).
    2. Our blue label Tire Sealant formula is for use on any tubeless tire and can be pre-installed to prevent flat tires on trailers, ATVs, mowers and wheelbarrows.
    3. Our red label Tube Sealant formula is designed to be used on tires with inner tubes.
    4. Slimepro Tubeless Bicycle sealant offers flat tire protection and bead sealing capabilities for performance bicycle tires with UST or conversion set-ups.

    Our Quick Spair aerosol sealant is designed as a temporary emergency repair for passenger vehicles to get you off the road and to a tire repair shop.

  • Why is Slime sealant only guaranteed for two years?

    Slime sealant is a liquid and therefore will evaporate over long periods of time. If your tire still has tread and is in good condition after 2 years, we recommend that the Slime inside be removed and replaced.

  • Will Slime Damage my wheel?

    No, Slime Tire Sealant contains rust and corrosion inhibitors that protect against damage for 2 years. We recommend after 2 years you remove the sealant and replace it with new Slime sealant to ensure optimal rust and corrosion protection.

  • Will Slime extend the life of my old tires?

    Yes, adding sealant to your tires can extend the tire life. Slime helps to maintain air pressure as well as reduce heat, limiting the wear and tear on the tire casing. As the sealant flows around the tire, it will coat the inner casing of the tire as well as fill cracks. If a tire is brittle, cracked, or significantly worn, we recommend replacing the tire, particularly on high speed vehicles. We do not recommend that you apply and leave slime in tires that are used over the road.

  • Will Slime pool at the base of the tire?

    Tubeless tire Slime has more adhesive characteristics, which allows it to cling to the inner casing of the tire longer. This helps to prevent vibration when the tire rotates and the sealant is once again forced to flow around the tire. Inner tubes are very slick, so when a bike or other tubed tire is stationary the sealant will pool relatively quickly at the base of the tire. It, too, will redistribute very quickly and evenly once the tire is in motion.

  • I have a tractor tire that contains a saline solution for ballast. Can I install Slime? 

    No. We cannot recommend or guarantee our product’s performance if added to a tire that already contains another product or liquid. If you would like to have the protection of Slime, you would need to remove the ballast solution and replace it with Slime.

  • What is the difference between Slime for ATV’s and Slime for Autos?

    There are 2 varieties of Slime sealant; one is specifically for tires with inner tubes and one is for the tires. Auto and ATV tires generally do not contain inner tubes. For these applications, we recommend our tire sealant formula. If your vehicle comes equipped with a tire pressure monitoring system (TPMS), we recommend that you use our yellow label TPMS Safe Formula. This formula is specially formulated not to clog or harm TPMS devices.

Quick Spair
  • After using the Quick Spair the puncture has not sealed. Why?

    It is possible the sealant did not reach the puncture due to the valve not being oriented to the correct position. This is critical, especially for the larger sealant cans. The puncture should be at the 6 O’clock position, otherwise the sealant will not properly dispense.

  • I recently used Quick Spair and my tire looks low. What happened?

    Quick Spair is designed as an emergency repair tool. It delivers only enough inflation to lift the wheel off of the road. Additional air can be added from a portable tire inflator if one is available at the time of the repair. A passenger vehicle tire that has been repaired with Quick Spair should be taken to a shop where it can be professionally and permanently repaired as soon as possible.

  • My quick Spair failed to dispense. What could be the problem?

    Be sure that the air hose or cone top is fully engaging the valve core. Additional pressure may be needed to ensure this.

Slime Pro Tubeless
  • Do I need a rim strip?

    It differs, if you have a UST rim you will not need the rim strip. If you are converting a standard tire and rim to a tubeless set-up you will need a rim strip to seal the spoke holes on the rim. Your local bike shop can help you with the conversion as well.

  • Does Slimepro Freeze?

    No. SlimePro contains an antifreeze additive that enables cyclists to ride in cold weather conditions as low as -4˚F (-20˚C).

  • Does Slimepro seal sidewall punctures or bead leaks?

    Slimepro Tubeless Sealant is not guaranteed to seal punctures outside of the tread area. It is a liquid sealant that coats the inside of the tire within the tread area. There is no way for the sealant to reach the sidewall; therefore it is not effective for this type of puncture.

  • Does Slimepro stay liquid inside the tire like the other Slime Sealants?

    Yes, the lifespan of the sealant will however depend heavily on the type of tire and the riding conditions. As a general rule, the lighter the tire and the thinner the wall, the more quickly the sealant will dry up. Extremely hot weather has been shown to accelerate the drying process.

  • Does Slimpro contain ammonia?

    Yes it does contain trace amounts of ammonia. SlimePro Tubeless Sealant contains much less ammonia than competing brands.

  • How do I clean out Slimepro Tubeless Sealant?

    Simply wipe or rinse out the tire with water and/or a wet rag. 

  • Is Slimepro latex based?

    Yes, the latex allows Slimepro to seal the bead of a conversion system.

  • What is the shelf life of Slimepro Tubeless Sealant?

    This will allow the product to remain effective for 2 years. If you intend to use a bottle you’ve had for a while, please be sure to shake the bottle vigorously prior to installation.

  • Will Slimepro rust my wheel?

    No, Slimepro Tubeless Sealant contains rust and corrosion inhibitors that protect against all forms of rust and corrosion.

Tire Care Accessories
  • What is the rubber cement in the Reamer Plugger kit for?

    Rubber cement may be applied to the plug to help inset it into the puncture. It also has the ability to soften the rubber so that when the cord is inserted with the glue, it will help the cord and the tire rubber to fuse together. This is exactly the process used to affix a “vulcanized patch” to an inner tube. Once the glue cures, a permanent repair has been achieved.

Tire Inflators
Tire Sealant
  • I have low profile tires, can I use Slime?

    Yes, try the yellow TPMS Safe Tire Sealant if your vehicle has a Tire Pressure Monitoring System. Slime also makes spare emergency flat tire repair kits that feature a tire inflator to air up the tire and slime to seal the puncture. Please use Slime only as an emergency repair on any passenger vehicle tire. A passenger vehicle tire treated with Slime should be taken to a tire repair shop at your earliest convenience for a permanent repair. Please tell your repair specialist that Slime is in the tire and ask for an RMA approved repair.

  • I installed Slime and it clogged my valve. What should I do?

    Simply take a wet rag and wipe the area around the valve. Next, remove the valve core and use a wet cotton swab to wipe the inside of the valve and the O-rings on the valve core. Re-insert the valve core and inflate the tire.

Tube Sealant
  • Can I install Slime into a bicycle inner tube with a Presta Valve?

    If you have a Presta valve on your bicycle, the best option is to use a Slime Smart Tube. These tubes are pre-filled with Slime Tube Sealant and install like a standard tube. It you wish to use the tube already on your wheel, check to see if the Presta valve is two piece. If the center is removable and the valve is in fact a two piece, Slime can be installed. Simply remove the core, allow the tire to completely deflate and squeeze in Slime. For best results, bypass the clear filler tube and squeeze Slime directly from the tip of the bottle into the valve.

  • Can I use tubeless Slime in my inner tube?

    We do not recommend using either of our two sealant formulas outside of their intended applications. The tubeless sealant utilizes a blend of rubber particles and fibers to treat large punctures in a multi-ply tire. The rubber particles are too large to effectively treat small punctures in a thin-ply tube.

  • How do I inflate a tube with a Presta valve?

    If you are asking this question, chances are you purchased a Presta tube in error. If you feel you have, we would recommend exchanging the tube for a Schrader tube. Otherwise, you will need to purchase a pump with the ability to inflate both types of valves or you will need to purchase what is called a Schrader adaptor, which will allow you to retrofit your existing pump.
