315/30R18 or 245/40R18 MT street DR
I want to get a pair of MT street drag radials, but I'm not sure if they fit on my e92 sport. I have stock spoke 189 18" rims.
The 3782R (265/40R18) has 10.6 Sidewall width, 9.6 Tread width, 26.5 Overall diameter. - fits an e90, but does not fit my e92 with sport suspension, they were rubbing my fenders on bumps or when I launched hard
The 3784R (P315/30R18) has 12.4 Sidewall width, 11 Tread width, 25.5 Overall diameter.
The 3780R (P245/40R18) has 9.6 Sidewall width, 8.5 Tread width, 25.8 Overall diameter.
I'd go with 315/30/r18, does anybody know if they fit?current: '12 E92 M3

A 315 is out of the question.
It seems the 245/40R/18 is your best choice.
If this is for the street (why?) look into Nitto as well.FOUR SPOTS left in the BoostAddict NO MERCY Domination Fantasy Football league, CLICK HERE
