your tires are fine you are running way to much tire pressure. run it down to 15 psi that was my sweet spot with the same size tire. another thing this you need to launch it harder at least 4500rpm. dont worry s197 gt's come with 31 spine axles its not gonna break. there should be no reason why not you can run a 8.5-8.6. shift at 6300-6500 if you got a tune

he said he's an auto so launching at 4500 is not possible without a new torque converter
I'll get a set of LCAs, a UCA, and drop my pressure to 15psi. I'll report back in a couple of weeks with results. I was kinda worried about dropping the pressure so low as my wheels really don't seem wide enough for the tire. At 30psi there is noticeable "cupping" of the tire but I'll give it a shot anyways.
