If i wanted to get something with a 3" lip is there a different offset i should use? Thanks for the help. Also with the Rota slipstreams in 15x7 they list a 35 and 40 offset, what is best for me.
    17x8 +25 245/35/17 would be "perfect."

    Lip depends on wheel design, and not just offset.

    Neither of those Rotas will work without spacers.

      Do you work in a tire shop?

      I have "euro weaves" w/ rolled fenders and got some free (rears only) 215/60/15s.
      Was wondering if they'd work with ie3s.

      I've ran 205/60/15s all around.
      Thought those were perfect height.
      Will these 215/60/15 be a problem in the rear?
      You can go oversized on the rear without nearly as much hassle as the front, yeah.

      I still wouldn't recommend that size tire though.

        Go with 15mm spacers. Easier to find, will look better, are universal (10s won't work with some wheels), and still won't be close to rubbing.

        60mm studs would be more than enough.

          What would have to be done to make this flush with a bit of poke....
          You'd have to tell me how you plan to mount them. E30 5lug, E36 5lug, adapters...can't say anything without that.

            I'm going to be fitting my ACT's on my new E28 that will be slammed, and these look like they need a stretch! what size tire should i run, and do you have a brand recommendation for all seasons?

            the wheels specs are:

            Fronts are 8.5Jx16H2 ET10
            Rears are 9.5Jx16H2 ET14
            I'd probably go with a 205/55 and 225/50 combo. You can downsize to 205/50 and 225/45, but tires are harder to find and you'll end up with more wheel gap.

            For all-seasons that are actually capable in the snow, anything Continental or Michelin make are good to go. The new Conti DWS series is amazing (not sure if you have it over there).

              17x9 et31 for the rears. 225/45
              Im trying to get them flush. With adapters.
              Im thinking getting it down to et10 for the rears. And et5 for the fronts. Just want some help on my measurements. Its a late model e30. I don't want them to poke to the point of being rediculous. Just be nice and flush. I dont know about my tire size selection. But I want a little stretch, but something I can still drive hard on when the time comes. Sorry for the essay.
              Thanks for any help bud.

              What I always say with bolt pattern conversions is to guess high. You can add spacers, but you can't subtract adapter.

              Go with 20mm all around, then you can add small spacers to get it just how you want it (if you'll even need to, 17x8 +9 and 17x9 +11 is already beautiful).

              For tires, your rear guess is off. Think 205/40 and 225/35, or just 215/40/17 all around. Those will all take hard driving just fine.

                Nope, that should be just fine.

                I would run Kumho XS or Falken RT-615 though. :p

                  The truck looks to have packed it in, so I might be relying on the 88 325 Auto for basic transportation this winter. Still have the bottlecaps - the suspension is lowered about 1.5"s according to the eibach sport spring kit brochure.

                  Want to convert the bottle caps to winter wheels and am looking at tire rack and local used snow tires on craig's list here in CT.

                  Question: what size tires can I get away with with these wheels and the lowered suspension?

                  I'm running the stock 195/65 14's w/o any rubbing - tire rack doesn't seem to offer a snow tire in that size.

                  I'm assuming that I can get away with 175/65 175/70 185/65 and 185/70 , but I'm not sure. 185/60 195/70??

                  Thanks, looking at 16" rims for the summer rubber :D
                  Every size you mentioned except 195/70 will be no problem. You may still even get away with that tall monster, but it'll be close. And it's nice to have a little space between fender and tire when there's snow caked on.

                    Need to know the wheel offsets here.

                      I'll wait till I wear these out first.
                      By the time that comes, I'll probably get bigger lips and I'll be looking to you for more offset questions :)

                        Thank you very much Jay. I have a lot of experience with fitting race tires under the E36 IP car with lots of ride height and camber changes, but am a complete novice with the e30. Looking forward to keeping it on the black with your help.

                        Thanks again.

                              ET20?

                              Nevermind, just remembered that is the offset of the TRM C1 wheels.

                                Thanks for the lead on the DWS's i would have completely skipped over them.

                                tire rack has them in 225/50 for the rear, but for the front i can run 205/45, 50, or 55. would the 205/45 look funny on a 8.5 wide wheel? the car will be very low on ground controls, so i'm not worried about wheel gap, i'm more worried about a tire too big, or too mismatched to the rear tire.

                                I'm going to ask my local tire guy about these conti's so hopefully i don't have to wait 6-12 weeks for tire rack.
