Widest rear wheel?

[rsporsche]

Wow. Yup. Another great wheel thread I overlooked. There are just so many!

Pretty amazing that Barry is able to get away with 10s. That is 2” wider than what I’m considering. 1” on the outside, 1” on the inside… I guess part of the secret to his success is stretching the narrow tires onto wide wheels? Like @rsporsche says, it’s not recommended but does help the tires clear the fenders

you have to know what kind of suspension Barry has - my guess is one with slimmer springs ... as i remember, he either is running coilovers or air bags. with 17" wheels, you gain a little clearance due to the slopes of struts / suspension. my car has 215/60-15's with carl nelson springs and i can tell you that if the suspension compressed a lot, the rear fender lip and sidewall of the tire would contact. there is a lot more curve to the sidewall so that it wouldn't contact with the tread but i can tell you that its close enough for me.

Interesting thread for sure. My car has 16 X 9 BBS RS with 245/45/16 Michelins on the rear. It has rolled fenders. They fit well, and I could (and will) lower the car a bit more. The only downside is that I am having trouble finding a good UHP summer tire in this size.

Do you know what offset?

Also, did you try without rolling fenders and found that it rubbed, or did you roll the fenders before putting those wheels on?

When your coupe is Turkis, nobody is looking at how fat your tires are......

That's a cool tool to have or have access to. Really simple way of checking.

I'd guess a serious tire/rim shop that's into upselling you into big wheels would have something like this?

you know, its not really that expensive - 100 bucks

100 usd, Indeed, not to much to know what you have, and can.

Beats tearing up a tire, or worse, a fender.

Yeah, this is really cool. Unfortunately it doesn’t let you check dynamically with suspension movement, unless I guess you could put a jack under the hub and compress the springs, then check again with the tool?

yep ... that's what you have to do. and this is only checking the wheel for clearance ... not the tire. i guess you could approximate the middle / edge of the tire
