Hi,

My car has the first M double spoke 17" rims, and I think they're 7.5" wide. The question is, will I be able to put on some 235/40 ZR17 Michelin Pilot Sport PS2 on front, and 245/40 ZR17 on back without rubbing or any drawbacks? Thanks

I also have these wheels, BBS 18". I'm a fan of stock looks but I may put these instead. My car has crappy tires at this moment (Ultra HPR? 225/40 R18) so I might buy the PS2's for these wheels instead. What aspect ratio should I use to keep the rolling diameter the same as with the original wheels?

P.D. Anyone knows which model these wheels are?

i've got a set on my 17" contours that fit fine except i'm running 225/45 fronts, dunno bout the 235s

235/40 all around will fit all four.
245 is for staggered wheels, which you don't have.

245/40-17 is too wide for a 7.5" rim.

Can't help with the BBS model in the pic.

My BBS' are 18 x 8.5 and I think I'll put these on as they are lighter. With these wheels will the 245's fit, I mean, can I put these on without the tires rubbing the rear fenders???
Q', what's staggered wheels?? (english is my 2nd languaje)

i had 235 all around on my contour m3 wheels
now i am running 225 front and 245 on the back
yes, front wheel is 7.5 inches wide and 235 is the widest you can fit on it.
but factory spec for 4 drs m3 are running 235 all around
