    90 325is with ksport coils
    rear: 16x9 et20, currently running 215/40/16 with 5mm spacers.

    I really want to move up to 225s on the rear, but 225/45s are laughably difficult to find. can I remove my 5mm spacer and run a 225/50 on the 16x9 without rubbing? I have some basic fender rolling done, but the 215/40s with the 5mm spacer rub with enough load.

      Looking at 15 x 8.5 wheels, any recommendations on tire size?

        I see most people run 205/45 but 205/50 has a more similar rolling diameter. Any difference in fit? Car is on H&R sports. Convertible with lower rear arches

        Thanks!
        I try! I wish I could stop by more often but life is seriously in the way.

        205/50 is the correct and more popular size. 205/45 is for stancey fitments.

What size tire can I run the front and the rear has 12mm solid riser bushings for the subframe there for less camber. Im also running H&R Race Springs. I have roller fenders.. I plan on drifting and aggressively driving the car so NO RUBBING ALOUD!!!!!!!!! lol
          You definitely bought the wrong wheels then. They don't fit properly at all, and will rub.

The wheels I got are a 17x10 square setup with a +15 et. I already run a 5mm spacer up front to clear basketweaves on my coilovers. What size spacer will I need to fit the fronts?
            15mm front spacers.

              205/50 for sure.

                Need to roll fenders and run 205/45s. Will still rub occasionally. Not a great fitment.

                  Should just squeeze by without rubbing. I'd suggest ANY tire but ASTs though, they are seriously awful.

                    85 325e on GC coils.

                    What size rubber should I run to avoid rubbing/fender rolling/stretch?
                    and will I need spacers?
                    Not possible without both stretch and rolling. 205/45 front 225/40 rear, rolled rears.

                      15x6.5 et 32 on a 205 tire
                      or
                      15x6.5 et 32 on a 215 tire.

                      I calculated max back space for 15" is 131mm and with tires about 129mm. Seems like if i ran 215's and they were really 215mm, I'd have issues. Can you confirm?


                      Thanks
                      Paper thin strut clearance. 205/50 will work, 205/55 will probably touch the struts.

                          Bad offset, won't work without spacers.

                            Nope. And you live in America, land of internet purchasing. Nothing is difficult to find!

                              This is about 20% of the info I need. See the first post.

                                Thanks Mystikal! I appreciate your time and knowledge.

                                Do you know where and what size hubcentric rings? Never heard of these before
