We kept lowered pressures reasonable, despite running beadlocks, and did some rock ’wheeling with about 10psi in the tires. Traction was impressive and we can expect that to get better as the tires break in further. The rubber compound seems fairly flexible and grips sandstone well. Time will tell if the lugs will chunk from running in the rocks. We’re sometimes hard on our tires when running boulders and jagged ledges, a case where harder compound tires tear less, but offer less traction for other uses.
