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

[moe30]

So I have a question, I'm picking up a e30 soon and it will probably be dropped on koni yellows with h&r race springs. Now to the question. I'm looking at a wheel that is 15 x 7.5 with a 30 offset... am I going to run into issues since the wheel is that wide or not? Like will I have to roll fenders or not.

[blefevre]

You'd need 3mm more space than an unrolled fender would provide. It's enough to rub on large dips, or when you have passengers.

Either roll, or back down to a 10-12mm.

Alright, just to clear things up before I order tires tomorrow.

Would I be better off just getting 225/50/15 tires and keep the stock hartge offset of et26? I like the beefy tire look so I think I might actually want 225s, assuming it fits without rubbing.

I am trying to avoid buying another set of spacers and rolling the fenders, unless I absolutly have to in order to get a near flush look.

I've seen guys run 205s on that setup, looks good to me.

kool, i only ask because ive never seen anyone with that setup running stretched tires, and i cant really pictures rota slipstreams with stretched tires.

18x8.5 +40 with 20mm adapter spacers. Unsure on suspension still, but what do i need to do to run this setup (most likely a diy coilover setup). I know I will have to roll my fenders, but I'm clueless on tire sizes. I assume something like 225/35/18 would be good.

18x8.5!!!!!!!! thats gonna be a huge wheel!

Hey I'm looking at some Riax 16x7 et42, will they fit and if so do I need spacers? Car is lowered 1.6" with kyb struts and vogtland springs if that matters any.

Hey, I'm another noobie with a question :)

1986 325e on KYB's and vogtlands. What fitment issues might I run into with a square 16x9 et13 Borbet Type A setup? And what tires would you recommend f/r?

Thanks!

[Mystikal]

would i need anything to mount up borbet type c's 15x7 et +35? or would they be a direct bolt up?

They'll bolt up, but you'll need hubcentric rings. They will be sunken pretty far into the fenders without spacers though.

Everything you guessed is dead-on.

fitment question:

1990 2dr
15x8 +20 TRMotorsport C1 on 225/50
H&R Sports
Bilstein sports
15mm springs pads in rear

will it fit? And will I need any spacers? I'm assuming I would need to roll all 4 fenders

Thanks in advance

Fairly aggressive roll on the rear, nothing needed on the front (it'll look scary though, with around 0.5-0.75 worth of tire poking out).

Fitment question:

89 325i 2dr. HnR sport plus billies. Lookin at the ESM 002.

16x7.5 - 4x100 - 20 offset - 57.1 center bore. How well will these fit? What size tires, 205/45/16? I have no idea what the center bore needs to be for our cars.

Thanks guys.

205/50 215/45 225/45 are all ideal. Those wheels were specifically made for our cars, nothing else is needed.

[Mystikal]

probably n00b question but can someone tell me what size tires this guy is running?

These are 16" i think, however anyone have an estimate on how wide they are? and what size tires hes using? looks to be the perfect amount of meat/stretch for that flush look that I really want to go with for my cabby...

Something like 16x8.5 215/40 front and 16x9.5 225/40 rear.

It is no way shape or form in need of pure performance tires (just an FYI). I do have the HFP suspension and SI sways on it now so it's slightly lowered with better response. I spend about 50 miles a day in the car. So


Wet Traction
Hydroplane Resistance (roads seem to be shitty with water retention)
Dry Traction
Noise
Ride
Steering Reponse
Treadwear (would like them to last longer then the 25k these did)
Snow/Ice Traction (has to have a tad for the 1 or 2 days of icy)
Price

It currently has the bridgestones that came on it. Which have been alright but wore really fast and slip pretty easily on wet pavement.

Thanks for your help!!

Just realized I never got a size from you. In any case look into the Nitto Neo-Gen, it's a fantastic all-season with comparable wet/dry performance to the 912 but with better winter traction and treadwear. I actually use it on my winter beater, as our roads only have snow/ice maybe 5-6 days a year. It may not reach your mileage goal, but it should be close; it also costs very little so that offsets it a bit.

[Mystikal]

If you don't mind also recommending one for my gf's civic. Her list looks like this:

Price
noise
wet traction
hydroplane resistance
treadwear (her's also lasted 25k..she currently has traction TA's)
ride
steering response
dry traction
snow/ice traction

Traction T/As are one of the longest lasting tires made today, might wanna expect a little less from anything else. I actually really like this tire for daily non-enthusiast duties. If you want to save a bit the Hankook H726 (I think that's the number) is great.

You'll need small spacers to clear the front struts, 5mm is enough. You will not need to roll the fenders, even with 225/50/15 tires.

I'd personally go with the 225. Actually I have, as I run that size on my 15x7 +20 BBS RZ378s. Flush look is better suited for wide wheels, IMO.

20mm spacers.
