Hi, whats the reccomended tyre pressure for 225/40/18's, im putting 33 psi in just now, you think this is ok ?

35 psi is the pressure recommended by WIM for the IS200, all round. But by all means experiment and see what works well for you.

I think Steve it depends on what size of wheels and tyres you have got.
Tony recommended me to have 38psi at the front and 36psi at the rear
And I've got 225 x 35 x19"

Ok guys, thanks for the info.

Best thing to do is give WIM a pm / email and see what they say.
I do know its 35 psi all round for standard wheels

I'm not 100% happy with my car's handling since I changed my 17" wheels for 18"s. I think I'll have a play with the tyre pressures to see if that helps, e.g. increase them slightly.

Steve.......I've been putting 38 in my Chicanes for awhile now, give it a go.
When I changed to my 18's I first noticed that the car didn't "roll/coast" as freely.....took a little getting used to at first.

Thanks Keith, I'll try 38 and see how I go.

I'm happier with the handling since I increased the pressure on my 18" Chicanes to 38psi all round. I need to drive it some more on different roads to check out if it really is back to where I want it, though.

I've been running 35psi all round on both the 17s before and now on 18s and handling is spot on, might try 38 for a bit though if there may be an improvement
