Overview
What is the Challenge Gravine Pro Handmade TLR built for?
The Gravine is the most aggressive tread in Challenge's lineup, made for more severe terrain. Deeper tread gives you more braking traction and better grip in loose gravel and on rockier ground, and the wide-spaced knobs shed mud and dirt and find traction where smaller tread patterns get overpowered. Road.cc recommended it in its best gravel tires review.
This is the PRO handmade version in 700 x 40 with black sidewalls. It pairs a 260 TPI Super Polyester casing with Challenge's SMARTplus compound, a tougher and more cut-resistant rubber that holds its edges longer on gravel. A second layer of puncture protection (PPS2) sits on the inside of the casing for rough roads and gravel. It is tubeless ready and compatible with both hooked rims and ISO/ETRTO-compliant hookless rims. Challenge recommends its Smart Tubeless Sealant for setup.

FAQ
Good questions
Get to know Challenge
There's more to Challenge than this one product. Our Challenge page has the full Challenge lineup we carry and more about the brand.
Visit the Challenge page →How does the Gravine compare to the Getaway and Gravel Grinder?
Challenge calls the Gravine the most aggressive tread in its lineup. Pick it for loose gravel, rocky ground and mud, where the Getaway and Gravel Grinder treads start to run out of grip.
Can I run it on hookless rims?
Yes. Challenge lists all of its handmade TLR tires from 33 to 45C, including this 700 x 40, as compatible with ISO/ETRTO-compliant hookless rims. It also works on hooked rims.
What does PPS2 mean?
Challenge builds its tires for rough roads and gravel with an additional layer of its Puncture Protection System fabric on the inside of the casing. That second layer is PPS2.
