IRC Formula Pro Tubeless

Wider Tread = Improved Puncture Resistance

We added a wider tread to all our Formula Pro Tubeless tires to better protect the casing and improve puncture resistance and boost durability. With improved sidewall protection and handling, this tire begs to be ridden over pavé and gravel.

These tires are available in hooked or hookless compatible options. Hookless tires can be used on both hooked or hookless wheels/rims. Hooked tires can only be used with hooked wheels/rims.

Rice Bran Ceramic Compound (RBCC)

All new Formula Pro Tires are crafted using the newly formulated high grip compound, RBCC², to ensure serious grip capability while having improved wear life.

X-GUARD: worldclass slice & puncture protection

The Formula Pro Tubeless X-Guard is constructed with a 40×40 TPI anti-puncture mesh, covering the entire casing from rim-line to rim-line. X-guard material is engineered and optimised for its superior slice protection qualities. We also used our newly formulated high grip compound, RBCC², to combine incredible traction with improved wear life.

Super Light (S-Light)

After a decade of manufacturing true Tubeless tires (without liquid sealant required), we wanted to squeeze out as much weight as possible. To achieve the game changing weight reduction we adopted a Tubeless Ready system for our Formula Pro Super Light (S-Light).
