Challenge Tire Grinder Pro

PPS2
Our tyres designed for rough roads, cobblestones, and gravel have an extra layer of PPS (PPS2) inside the casing. This second layer slightly adds weight to our tyres, so we use it for tougher conditions, like all our PRO Series Gavel range, for example.

Corazza silver
Corazza Silver is a double-layer carcass reinforcement applied inside the tread down to the bead, improving resistance to cuts and punctures on rough surfaces or uneven roads.

SMART plus
A more robust rubber compound that is more resistant to cuts.

Super Polyester 260TPI
High thread count (220-300 tpi). Much softer and more durable than nylon, polyester is waterproof and very long-lasting.
