Just so someone may want to know my bias towards Uniroyal tires, I have bought 12 tires over the years and all failed.
8 where on passenger vehicles and all had tread seperation failures. All were at or close to recommended pressures to and not over loaded. Another set was on a P- series van with 6600 lbs. on the axle, dealer installed, and at full sideway pressure, which was 65 lbs. Load range 'D'. Two failed on the same day! dealler said we were running them underinflated. I responded by saying they were still at the pressure your people set them to last week. He said we must run them at 80 psi!!! Within 2 months two more failed, I took them all off and called it a lesson. More than 1 failed by splitting a sidewall.
