I think he had about 16 to 20 in them as I told him I like 16 to 18 psi in mine. But we always put about 35 to 40 in them first to seat the beads. He has always run bias slicks and screwed them to the rim. I told him I dont have my radials screwed to my rims and many say they dont screw them so he did not. He did say he actually tried to put screws in them and that these M/T 14 x 32 radial slicks just kept pushing the screws back out and they would not go in anyway. He was mainly concerned with how the tire seemed to move almost 6 inches on the one pass he put on them the other day. Course the car hooked great and did a big wheelstand. Ron
