ASK ALL WHEEL/TIRE FITMENT QUESTIONS HERE - The Official Wheel/Tire Fitment Thread

I can't find a definitive answer to this.

I have 14in. basket weaves with 205 wide tires - BFG Traction T/A.

Can I fit 15mm H&R spacers in the REAR without rubbing? I will be lowering the car on H&R sports very soon, will it rub then?

Yup, no problem. I believe the magic numbers I spec'd a while back for stock weaves was 15mm front and 20mm rear spacing would be okay, with 195 tires. You'll be fine with 15mm and 205s.

Ok crazy fitiment question here:

I have 2 Merc Benz AMG wheels, size 18x9, ET23, 5x112. If I use a 4x100 to 5x112 adapter (dangerous, I know) which is 20mm thick, will these wheels fit on the rear?

I am dropped on Eibach sports and Bilsteins. If so, what type of tire sizes am I looking at? Car is a 1989 if that helps.

Thanx!

It'll be extremely tough.

I have the exact same dilemma right now, as I'm contemplating putting my 18x9 +22 5x120 BBS' from my E36 onto my E30 with 18-20mm adapters. Because of the sheer height of the wheel, there is very little room left to gain space from tire stretching. By this I mean a 16x9 +3 wheel can easily fit with a fender roll and 205/45 tires, but once you add 2" more wheel...it gets TOUGH.

I wouldn't try it, unless you're willing to either a) invest in flaring or b) give up without being mad.

Okay I have one. The car is a 90 325is with GC coils, front camber/casterplates and IE weld in rear camber toe kit. Fenders and quarters are not rolled.

The wheels I want to fit are:

Front
7.5x16 et27 I currently run a 3mm spacer to clear my Massive street kit, not sure if I would need it with these wheels.

Rear
9x16 et21


What tire sizes am I looking at running to make these fit? Will I need spacers front or rear?

The front can easily handle 225/45s without any modification, however, the rear will be much more difficult. Your maximum there would be 215/45/16, so you may want to just use that size all around.

If you're willing to crank up the rear camber (read: more negative than stock) you could do the 225/45 all around though.

Fitment Question:
88 325is IE st3 springs

15x8 et20
Tire Hankook rs3 225/45/15

THANKS!!!

Perfect.

little update, I ended up having to go with 215/40/16 up front, which happens to be exact same OD as the 245/35s in back. Only problems will be more drastic stagger and stretching 215s on an 8.5" wheel.

I'm still looking for a better fitment option for my next set of tires if anyone has any suggestions.

I didn't ignore your other q's, just noticed this as I was replying to the first and decided to just reply here.

Keeping the OD's the same was a smart move. For your next setup I'd just run 225/45/16 all around.

I have some Kopi Alpina reps 17x7.5 ET20 which are stretching 215/40/R17 tires. I bought them needing new tires, I'm hoping I can do 225/40/R17 because I really don't like stretch.

No fender pulls or rolls, car is a little lower than usual, but not much. Doesn't rub anything as is. Might have some clearance issues in the front I'm guessing with that plastic shroud, but I could just take it off.

If bigger tires won't happen without rolls, pulls, spacers, then I guess I'll stick with the 215s.

What do you guys think?

You're at the maximum for that wheel without fender modification.

A nice broad 215/40 should remove any stretch. Look for wider section widths of perhaps 8.7"+.

Late model, I'm asking for a serious roll/pull aren't I?

Car is on coilovers. 318is.

16x7 Alpinas, I think they're et28, they might be different though.

225/45/16? Any rolling, etc? Dropped on races.

[E30SPDFRK]

16x10 in the back, whats the highest offset I can run before I hit the trailing arm/spring perch?

+13 is safe.

I want them to be as flush as possible. I did some measuring when you were gone and I think et18 is going to just clear. Worst case scenerio I'll just trim the trailing arm a little. ;)

Really? Damn I would have thought that with that offset 225's would be be easy in the rear. How much camber are we talking about? Would rolling the rear fender lips help.

I was hoping for at least a 225 in the rear, 215's on a 9'' rim will have a fair bit of stretch will they not?

Could I get away with a 215/45 or is 215/40 my best bet? 215/45 is just over 10mm larger sidewall than 215/40, too much?

Mystikal you rock!!! Thanks for the help.

Oh yeah, serious roll. Earlier cars can pull it off, but that's a massive section width for a late model to take in.

225/45 would fit perfect, no rolling.

Yup, I'd say you're on the mark. I usually leave a few mm to be safe in my quotes, just to make up for tires with large curb protectors and the like
