just order a new set of wheel that is 17 x 7 40offset. for a 09 jcw clubman. stock suspension. as of today.. but AST-5100 is on order. wont be install till next month.
but it seem that there is not many choices with 225/40/17.

so the question is will 225/45/17 too big in size or would going 235/40/17 be better. remember the car will be lower, but not slam.

I was going to try out the new Michelin PSS. if I recall the PS2, it run wide.

 

225/45/17 will fit... That is what I am running and I have no rubbing. See picture link in my signature. NOTE: I have stock rims at stock height also...

 

You can use this site as a guide to determine wheel fitment and side wall
increase/decrease. Can put in a few different size tires for a quick side by side comparison.

The 45 profile while closer to stock, is a bit taller so depending on the tire, you may sacrafice lateral stability during hard cornering....basically wider is not always better.

The best compromise for stock rims and alike I have found is the 215/40/17. And a fairly large selection to choose from.

 

on a 2010 S coupe w/ OEM wheels. Michelin PS2's. No rubbing.

Also reduced about 1/2 of the speedo error per GPS before and after tire change from the 205/45 stock.

 

so i guess my best bet is to use 215/40/17...

 

I'm looking at the hankook ventus v12's and i'm wondering if i'm better off with the 215/45/17's or 225/45/17's

From the sound of these posts would i be better off with the 215/45/17's?

 

I think so ... I just end up buying the new pilot super sport 215/45/17
