Optimum Tire Pressure for Traction? PS4S 295/30R20

DeTh · 03-22-2023, 06:46 AM

Just picked up some Titan 7 TS-5's from a member here on the forum (I love them!!) and wondering about optimum tire pressure for roll racing.

I'm currently Stage 2 on 93, with PS4S 295/30R20's in the rear. In this race (where I scared the ever-living shit out of my friend with how much I was spinning) https://youtu.be/-0I0yUpb1Eo
I was running around 32 PSI. Should I lower it to 26? 28? Just wondering what you guys are doing for traction!

PS4S is weird because of the sidewall but yeah 32 is too high.

I probably wouldn't go below 26 on that tire.
