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

I have a set of borbet type h 15x7 et25mm

Just trying to figure out what size hub rings I need.. I know the measurements go from a 64mm cb to a 57.1mm hub but I wanted to figure where I should buy the rings (heard don't go through tire rack or discount tire direct) and if spacers would be needed. Still a bit of a noob when it comes to wheel fitment

Local wheel shops if you're in a city, or yes Tirerack and DTD can get you rings I'm not sure why you would be discouraged from them.

Goal: Not to roll my fenders
Car: 85 eta
Suspension: HR Race and Billy Sports
Desired wheel size: 17"
Question: How wide of wheels can I fit without fender modification? I've seen people stuff 17x8 front and 17x9 rear. I am going for square setup, so maybe 17x8 front and rear? Then leads the question, recommended tire size? And which offset of wheel should i shoot for?

Thanks ahead of time Jay!

Just use what I told Apex Wheels to use years ago on their old 4x100 line: 17x8 +25. Will fit 215/40s without rubbing easily.

I just got some 17x9 et22 str 518, what would be a good tire size to run all around the cah?

First off, they don't fit without spacers. You will need a 10-12mm spacer to safely clear the front struts. Once you do that, the rears will be sunken in. So buy a full set of 10-15mm spacers and run 205/40 tires.

I was confused, I remeasured my rs' s and they are 16x7.5, not 16x8. Was shooting for 205/45/16, but I better rethink the plan now, lol. Im not looking for a square sidewall, I want a moderate stretch, nothing silly. Should I bump it back to a 195?

Definitely 195/45s. The 205/45s will totally square on a 7.5".

I actually have spacers on there. I think theyre 10mm spacers

Would 205/45-16 look strange on a square 16x8 +20 setup? Tire choice kinda sucks.

Thank you sir, I appreciate the heads up!

Sorry I have another question:
I'm also looking to purchase 17x8 Apex ARC-8 et25 and I plan to run 20mm spacers to clear my BBK I have BC Racing coilovers and want to know if they will fit and what modifications are required for them to fit. Please let me know and what size tire can I run?
Btw the car is an 84

Heard that for insurance reasons DTd and tire race won't
Sell to you
Because it's a wheel that isn't designed to fit
The car so you will get
The runaround and no answer

I'm looking at some Work XSA's (16x8+23) and they have some 205/45/16 falkens on them. Are there spacers in my future?

[itskingsteelo]

Ooooooooooone more thing, would 205/40 sized tires look stretched or normal? Someone also told me i could run 215-45 which would be better for everyday use

Tires on 16" style 5's with 20mm adaptors?

[aworthybrother]

12-15mm spacers all around with 205/50/16 tires.

Hi,

Can i run 20mm adapter spacer with no rubbing? My fenders are not rolled.

(Ronal LS 16x7.5 5x120 et35)

[Jand3rson]

Jay, what's a decent tire in 205/50/16 that doesn't have a super tall sidewall? I've got 204/45 Federals right now, and I really don't like them much, plus it's getting close to tone for new tires. Along with that, I'd like to fill my wheel wells a tad more, but the 205/50 Feds I had on there before looked gargantuan. What do you recommend? The looks of a tire are important to me. Thanks!

What is best ET to use?

1989 325I Lowered on HR Sports with Bilstein Sports. Picked up a set of 4x100 to 5x120 18mm adapters. I have a couple of 5 series rims that I thought I could use, I added the 18mm instead of subtracting. So I am guessing they will be "Hella Flush" with a ET2? I am assuming most E36 rims will work, starting with around 40mm offset, then spacers netting about 20? Am I looking at this right?
