Thread: Tire Pressure

Slowly raise your rear tp. Other than that I think I talked this one to death

He is correct.

Keeping the front tire pressure the same for both conditions....

Higher rear tire pressure causes rotation by reducing the contact patch. This is preferred because it is more controllable.

Lowering (like go down to 15~20 psi) rear tire pressure causes the tire to produce less lateral force and operate at higher slip angles. This is much more entertaining and I would suspect faster if you can dial it in. (higher slip angle means the rear end will "hang" out more when loaded, but the lower sidewall stiffness might be tricky in some slalom situations with a lot of left right weight transition)

Except kojima says to lower the pressure! Either way ill try both i think the higher slip/ lower tp would be benificial to autox and the hight tp for hpde etc.

Did you read my post?

I was just making the argument of why high pressure is preferred.

I have only played with the lower rear pressure for fun. If someone wanted to dedicate a whole auto-X season to really dialing it in, it might be faster. High rear tire pressure you know what you are going to get.

I did hense why i said the lower pressure which is less predictable may be better for autox where high manouverability is key.

I will continue to play with tp with my current rs2 hankooks snd post up dates. So far im at 38/33 f/r. I think i can go higher on both. I think i will try 40/42 next time and tune frome there. Thanks all for the input.
