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

i have an 89 325i. i picked up 15x7 ix weaves. i was thinking of running 20mm spacers all around. my fenders are already rolled. my question to you is; what size tire would be better with this set up? 205 50 15, or a streched 195 50 15.

im on bilstein sport suspension

You could easily put a 225/50 on, or 205/55 is the correct diameter. You won't see any stretch at all with a 195, and the wheels will be FAR too sunken in the fenders to aim for stretch anyway.

I'm looking for widest tire on an early(86) 325e sedan(large arch) with 16x8 et20 and 5mm spacers or any size spacer that brings me biggest tire fitment, I have no problem on rolling or pulling fenders.

On suspension it has billy sports with H&R 1.5 drop front and 1.3 back...

If you're willing to get crazy with the roller, 245/45 is possible.

Wheel Specs:
front. 17 x 8.5" et56
rear. 17 x 9.5" et56

I will be running adapters as well.
Will be going on an 87 metal bumper e30.

Plan on rolling fenders, what size adapters will I need?

Flush: 40mm front/rear

I just purchased a set of style 5's (were re-drilled to 4x100) 16x8 et23 all around, with 3mm spacers in the front (barely rubbing caliper, might to shave a bit off)

What tires would you recommend? 205/45-16? 215? 225? Fender rolling/pulling will be done if I have to.

225/45 will work with a flat fender roll in the rear

Im wondering for my setup if using those 20mm 4x100 to 5x120 adapters will work to put these on an early body, or is there 15mm adapters available to convert 4 to 5 I only found the 20mm ones? its only temporarily and im running stock suspension but will lower later and maybe convert to five lug but if this works and can be lowered to help it, I might not do the 5 lug conversion just the adapters and the drop then. will 17x8.5 ET41 or 17x8.5 ET13 work in the front and 17x10 ET15 work in the rear? if fender rolling has to happen Ill do it which im assuming. also if I cant get the 17x10s I was just gonna run 17x8.5 all around what would be needed to do that also? what size tire to run, the stretched look is fine with me aswell, what ever is takes to stuff these under there as long as they look good. oh and if just do the five lug in the back then Im assuming since that 20mm adapter wouldnt be there, that would give me 20mm to work with in the back, would that help to put those 17x10s in the rear? thanks

Run the 17x8.5 +41 in the front, with 20mm adapters. 17x10 +15 in the rear will work with the E30 M3 hubs, an aggressive fender PULL, and 225/35/17 tires.

I am looking to run DS1 17x7.5 wheels (et40?) with 20mm adapters on my 91 vert. Would this work without fender rolling? If so what size tires would be necessary? Not a huge fan of stretched tires, so I don't mind rolling if I have to.

Thanks

They're +41. That will work fine, with 215/40 tires and no rolling.

245/45 front and rear? or rear alone??

Car will go to paint shop way after roll and wheels. So I can afford to tell the guy who rolls to go crazy.

I've got MiM 1900's 15x7 et13, what size spacers and tire fitment would make them sit flush?

Also I'm thinking about getting some Diamond Racing steelies, what sizes(15"x?)/fitment would be best to make them sit flush?
This is for an '85 euro bumper sedan. Rolled and un-rolled would be helpful.
Thanks in advance

Just put new lips on my schmits 8.5" rear and 7.5" front I calculated the offsets to be about an et 22 front and rear ( i may be off a mm or 2) .My fenders will be rolled and im lowered on race springs.Would it be better to go 215 45 up front and 225 45 in the rear or 225 45 all around?

thanks

Help,Im just not sure if the 225 will look right if the fronts are 7.5" and rear 8.5" Im confident from what I read that size will fit just not sure if I should run all 4 that size?

MiM: 10mm rear spacers, 195/55 tires

Diamond: 15x8.5 +13 15x9.5 +13 would be beautiful (if possible). 205/50 and 215/45 tires. This will require a flat fender roll as well as linear springs (coilovers). For unrolled subtract an inch from each wheel and back the tires down to 195/55 and 205/50.

As I said, it'll work fine but the tire profile will look different front/rear. Your choice.
