WTB Completes TCS System with Tubeless Tire Sealant

Posted by on

GARDA, ITALY – October 15th, 2021 – TCS Tubeless Tire Sealant is a dependable, thoroughly-tested sealant formula that completes WTB’s patented TCS system of tubeless tires, rims, wheels, valves, tape and sealant. WTB’s proprietary formula quickly repairs ¼” (6mm) punctures by encapsulating fibers and crystalline particles within the puncture to create a flexible, long-lasting repair. TCS Tubeless Tire Sealant uses an ammonia-free tackifying process to seal punctures rather than the evaporative effects of many ammonia-based formulas. As a result, our sealant performs better in wet, unforgiving conditions where other sealants have trouble clotting due to minimal evaporation. WTB sealant also features synthetic latex to reduce the risk of an allergic reaction for individuals with allergies to natural latex products.


TCS Tubeless Tire Sealant is optimized for temperatures down to 15°F (-9.4°C), which increases sealing performance without altering the formula for extremely cold conditions. Competitors’ formulas often use more antifreeze in order to operate in temps down to 0°F or below. Accepting higher minimum temps allowed WTB to improve sealing performance by reducing the amount of antifreeze and replacing it with additional synthetic latex. 

Sealant may seem like a fairly straightforward product to develop. It simply has to sit in a tire and seal punctures, right? Even if it were that simple, we had no desire to relabel somebody else's formula and call it good.  We developed and thoroughly tested our sealant for two years to be completely confident that TCS Tubeless Tire Sealant is the best option for quickly and dependably repairing ¼” (6mm) punctures. 

TCS Tubeless Tire Sealant is available in four sizes; 4oz and 8oz bottles for installing up to four tires and larger 16oz and 32oz bottles for every workbench. All bottles feature measuring gradients in both ounces and milliliters to easily determine how much sealant is being poured. Our all-new TCS Tubeless Tire Sealant is currently available in Europe and will be available on bike shop shelves across North America this fall.
