I´m going to buy new winter tires and 18" or 17" rims and I need to know if the back and front rims are diffrent in size? also what is the ET value for the rims for my car? I have a 2003 2.5i Z4..
IMO, You're best to go down to 17's for winter for overall performance and cost. 17's with 7.5" to 8" width - tires 225/45/17 - plenty of options out there on this size.highstream said:I´m going to buy new winter tires and 18" rims and I need to know if the back and front rims are diffrent in size? also what is the ET value for the rims for my car?

X2 and with an 8" wheel a 40 mm ET...Caddyshk said:IMO, You're best to go down to 17's for winter for overall performance and cost. 17's with 7.5" to 8" width - tires 225/45/17 - plenty of options out there on this size.
Got the ET from tire rack and it looks like for a 7" wheel anything from about 35 to 47 would work... All of the ASA wheels in 7" are 40 mm. 47 mm is the ET for pretty much all of the original BMW wheels in 8".highstream said:hmm talked to my dealer and they said ET:47 on a 17" wheel..
