Fronts are 225/45ZR18, Rears are 255/40ZR18.

Now the question is, will those size tires fit on my stock 2006 rims. Which are 18" x 8.0 Front, and 18" x 8.5 Rear.

Usually, I would keep the factory size, but a friend of mine has some tires laying around for a cheap price.

Thanks alot, btw the tires are Michelin Pilot Sport, Z rated performance tires from an M3

 

rears are not as tall as oem (245.45.18) but you might not have problems. I don't remember the % diff that is allowed.

I didn't go ape $hit on you for not searching b/c you have been here for over 3 years...but you can search to find out the answer.

 

Is it really that difficult to get an answer, I asked the forums cause im on here everyday, i dont post too much but w.e. I trust you guys before any other place

I believe there is a sticky with regard to tire size and how much of a diff is allowed, maybe 3%?. I remember finding it in a search.. lol

Good luck,

EDIT: LOL! I just found it by going into the proper forum.....

Thanks alot man, appreciate it. So the diameter difference is 2.44%, anyone think i'll run into any problems with them?

 

you should be ok, i think 3% is the number...since i thought it was that before reality350 posted and he said the same thing i'm pretty sure now that it was 3%.

 

LOL. I prefer that the rear tires are 10mm taller than the front with VDC, but this set-up will be OK with TCS.
