if you were rolling that bad you seriously need to bump the pressure up.That makes sense... cuz drift cars use like 15psi on the back and 30 on the frontr.... hmmm....
Ill try that then, and i didnt use chalk, but remember the white lettering i did on my tires???... thst was... the chalk. Lol
get some chalk and mark your tires start at a higher psi and then bleed down until the chalk stops wearing off right at the edge of the tread without being on the sidewall. make note of what psi this happens at and then you have your starting pressure every time and can adjust accordingly to track conditions.
