Tyre Preasures

[Andy_C77]

Hi folks. I've got a '02 IS200 SE which I've owned for about 6months now when I bought the car it handled fine but after refurbishing the wheels and swopping them around I noticed the handling had deteriorated, I began to think maybe the dampers needed changing as the car is 14years old and I have no service history or maybe its how its meant to be so I was looking in to IS200 Sport suspension, and then yesterday I had a brain wave, Tyre Pressures so out I go to check them, the rear drivers side was 50psi and all the others ranged between 29psi and 35psi. So I've set them all to 39psi as a starting point as the information plaque on the 'B'pilar is for the 215/45/17 tyre, but all the tyres on my IS are 225/45/17.

 

Anyway I was wondering what pressures do other people run? Do you run different pressures front to back? 

 

Sorry for the rambling, I thought if I wrote out how I found the solution to my problem of the wayward handling then it might help someone else how has the same issue.

38psi seems much to high, I have 225's on the 18inch Areo wheels and run with 33psi fronts and 30psi rears, perfect.

35 psi all round for the IS200, and make sure the geometry is set to WIM settings to avoid the inner tyre wear
