18" Wheels- What Pressure Are You Running?

[denbailey101]

Hi everybody, I have searched high and low through the forum for a definitive answer without luck.

I have a 99 IS200 Manual but with aftermarket 18" alloys on and 225 40 18 tyres.

What tyre pressures do you guys use? Have been set at 35psi at the mo but i think i need to increase as its wearing on the shoulders more than the centre (front and rear tyres).

I did increase them before but steering was noticeably lighter and did not feel 'planted'. Thinking maybe go for 38psi all round this time for a starting point.

What do the hallowed LOC think?

Any thoughts?

Thanks in advance, Den

I run 35 or 36psi maximum as with you I do not feel comfortable when the steering gets too light. I do not have any current issues with tyre wear. My geometry was set up by WIM a couple of years ago.
