Wider rims seems like it could help and more PSI. We run a 30x9 D05 Hoosier, on a 10" rim. Our slower (1.4X & 6.9X's best) Chevelle, that leaves off a TB at 3600 w/ a 1.76 glide, used to wrap the tires a lot before we started working on the shocks in the rear and up front. Also added a weld-in anti roll bar. Every combo and car is different. We got ~250 runs out of our last set of tires. I set up a go-pro on the ground and near the rear tires during prepped TnT session and watched each launch in slo mo. To adjust shocks and tires. We kept bumping the tire pressure 1/2 psi at a time until we found our limit around 22 psi. We run 18-21 in the midst of Michigan summer and hot lapping it. If any of that helps...
