I have a Chevy S-10 regular cab/regular bed. I had to replace the original Tiger Paws after they developed deep cracks along the bead. I chose BFG Radial T/As for their reputation as a touring tire. Initially the handling and ride was great.
My dealer, unfortunately, set the tire pressure at 35psi all around. When I went to rotate them (about 10k miles), I noticed that the rears were cupped (the center tread was noticeably shorter that the surrounding tread). With these on the front, the truck handles poorly. I left the fronts at 35 psi, and lowered the rears to 28 psi. The dealer went bankrupt earlier this year (of course), so I can’t squawk to them.
I’ve tried everything from 20 to 35 psi on the front to counteract the cupping, but it drifts all over. Any ideas on curing this handling and wear problem? What about finding the optimum tire pressure for a pickup’s front and rear tires?
