I need someone that has run this set up to confirm. Will a 275-30 fit on a ZCP front wheel with no rubbing on a E92? I've seen the E90 threads but haven't seen a definite yes on a E92. I need to order tires today or tomorrow before the Michelin rebate ends...........Phil

Tech, thanks for the info. I've played with the calculator far too many times to count. I need a real world yes or no.....................Phil

OK this has been up since 10ish this morning with about 75 views. I'm gonna step out on the branch and say no one has done it yet. Well now.....what a quandary.......I guess I'll be the forum crash test dummy and give it a try. I'll wait until my track wheels arrive and then do it. This will give me something to ride on if I have to go to a 265......I'll keep you guys posted........Phil

Trying to avoid that.....I will be changing wheels from time to time for track use. I'm going to try it and see what the verdict is. I can't believe no one has given it a try besides E90 guys.............Phil

You already know I've been waiting for you to pull the trigger on the 275/295 setup on an E92

C'mon fellas someone has got to pull the trigger. I'll order the tires but I won't mount them for a couple more weeks. I'm waiting for my track wheels to be delivered.................Phil

planning 265/35 front, 295/30 rear with AD08 on ZCP wheels~ OR if PSS 285/30 is available, will do 255/35 , 285/30 with PSS

265/35 in front is too tall in most cases

Forget the offset of ZCP fronts but thought it was low 30s? I always thought all E9x cars would have the same room up front - what makes you think they are not? On my E90 I run a 275/30 AD08 (runs wide) on 9" wide ET22 front (stock suspension) and it works well. Slight rub on full lock and also under full compression. Running -1.5 camber up front. Pretty tight clearance to the strut but it works.

Edit to add that 265/35 is not going to work, too tall. Also if you can hold off I would recommend 255/35, 285/30 set-up if you can deal with the limited choices now. I would like to get more steering feel back up front and think the 285/30 rear would be a little better than 295/30 I have. Esp for tires like the AD08 and PSS, both of which run pretty wide.
