I would like to install Michelin PS2s on the stock wheels. Per the Michelin website the 225/45 and 265/40 look to be good candidates.

I have a couple of questions you can help me with. The 265/40 requires a 9.0" rim width. Will there be a problem with this tire on a 8.5" rim? Has anyone tried this? Any experiences? What is the maximum mismatch in radius or revolutions/mile acceptable before the ABS starts to act-up?

Thanks in advance.

It is not recommended to put a 265mm tire on a 8.5" wheel. The Wheel can not property support the tire and it probably wont perform the way it should. The 225/45/17 in the front will work just fine. I had the PS2 on my stock 2001 17s before i opted for the 18" upgrade. Personally i felt the PS2 was TOO soft of a tire. Its not a as great as i thought it would be. If i could do it all over again for that set i would go with the basic Pilot Sport.

I had 225/45/17 in the front and 255/40/17 in the rears.


My favorite set of tires that i have ever purchased would have to be the Bridgeston S-03s. Absolutly best tire i have had.....And i go through a set every about every 3-6months...
