Gravel Grinder Pro Tubeless Tire

The Challenge Gravel Grinder Pro Tubeless Tire pairs a handmade 260 TPI Super Polyester casing with SMARTplus, a tougher rubber that resists cuts and keeps tread edges sharp longer. PPS2 adds an additional protective layer inside the casing for rough roads, cobbles, and gravel. The diamond center clears mud and grips grass and sand, and the wide side knobs bite into soft ground.

What Our Gearhead® Experts Are Saying:

“Hookless wheelsets were never a reason for me to skip this tire, since compliant hookless rims are a listed fit across the 33c to 40c range. I seat it snug and add Challenge Smart Tubeless Sealant, which is how I set it up.”
