Frequently Asked Questions
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.
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.
PSI (pounds per square inch) standard tire pressure reading in the USA
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 Slime’s Warranty Policy for its Tire Inflators and Air Pressure Gauges?
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. If the store return timeframe has expired but the purchase was less than 1 year ago, please call Slime Customer Service at 1-888-457-5463 or 805-489-0490.
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 ⅛” (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.
Our yellow label TPMS Safe Tire Sealant is designed for use on vehicles with Tire Pressure Monitoring Systems (TPMS).
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.
Our red label Tube Sealant formula is designed to be used on tires with inner tubes.
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 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.
