If you've ever wondered how the tires on WRC cars can withstand getting slammed into boulders and smacking curbs, you're not alone. It turns out those specially made rally tires are constructed in a completely different manner than your average road tire, and the is here to explain it all.
Unlike your average road tire, gravel tires use a much more thick-skinned construction to help protect against hitting sharp rocks and broken pavement at speed. The sidewalls are much more fortified, aiding against a de-bead or separation from the patch.
And the tread pattern is completely different as well. In order to cut through gravel and latch onto loose surfaces, rally tires have a much softer compound and fat tread blocks useful for digging in and grabbing onto whatever's under the car.
But that's just the tip of the iceberg. Pascal of Team O'Neil lays out the different kinds of tread patterns available, as well as different types of compounds and sizes to choose from. Watch for yourself and learn everything there is to know.
