20x10.5 +32. A little over ambitious?

[downedzephyr]

Hey Fellow Coupers!
I know this should be in the suspension forum, but this is a time sensitive issue and the Coupe main section gets more traffic. Anyways...

I'm currently speaking with a wheel company about a sponsorship, and the wheels they are proposing are 20x9 +25 up front, and 20x10.5 +32 in the rear. I was wondering if it would be possible to run the 20x10.5 +32 in the rear with only camber, fender rolling, and stretched tires. If so, I'll go ahead with this deal and make this happen!

[alphapig]

Do it.

[downedzephyr]

can i get it to fit without pulling my fenders though?

Put a 225/35 on the 10.5 and you won't have any issues

No one really knows if it will fit. Based on my calculations though if I were to put a width like that on my setup specifically, (ride height, camber, and probably a 235 wide tire), I wouldn't have any outer clearance issues. It will actually stick out less than my setup. Now I'm not sure about inner wheel well clearance and hitting the struts and all that. But I think that would be an easy issue to clear up (just add spacers).

This is exciting lol. Obviously front will fit. Roll rears, add camber, and stretch tires. I'm debating to go 10 or 10.5 next setup. If I go 10.5 I will use a 235 wide tire to play it safe so that I wouldn't rub. Oh actually with 20's you can go 235/30

I say go for it man. Someone has to experiment with it. Also you're getting sponsored so at least some of the wheel cost is covered. Worst case scenario do a fender pull and they'll look great! But like I said, from the outside it will look pretty close to mine. Mine "fit without issues" but we may have different standards. Good luck and lmk if you need any help.

Oilsink, Loop, and Bundath should have some ideas also. Phenom is running 10 or 10.5 in rear but I think his offset is +45 but you could use that as a reference

Im running 235 30 tires from what I know with a +40 offset If I rolled my fenders I could use a 15mm spacer and be cambered as fuuuuuuuu hahaha. Try it out I'de love to see how this looks keep us updated. My new wheels should be a lot more flush just gotta wait about a month before there ready though. :/

After speaking with the company, the price they've offered me isn't all that fantastic; given the quality of the wheels they've offered me I'd much rather spend a bit more than the price they've quoted me to get some nice multi-piece wheels. However, if the company is willing to come down on the price I may go through with this.

[IBCoupe]

I'd recommend stretched tires. Keep us posted. I think you'd run into issues, but with rolled fenders and the camber, you might be spot on.

I'm actually more worried about your fronts.

[dangeris]

I would have to agree with the stretched tires. Partial sponsorships prices suck at times but it comes down to what you really want

I think the front's would fit no problem.

Yeah man, don't settle, even if it's sponsored. But I bet someone like you already knows this.

[downedzephyr]

Company said they'd be willing to offer me 20x9 +25 all the way around for $300 less. I'll probably pull the trigger on this one

Reviving an old thread instead of starting a new one lol.

I'm getting the same wheels setup as another user on here. This is his car:



20x8.5+32 235/30/20 Front
20x10.5+30 275/30/20 Rear

Trying to get a definitive answer on tires, not knowing too much about sizing. From the pictures he posted, the fronts look like they have a really nice stretch, could maybe even go a bit bigger, but that's just opinion based on looking at the picture. The rears look really meaty though. What's a good tire size to yield a nice looking stretch to match the front? From a full side profile, I'd like the tires to look even, as oppose to the rears looking bigger and meatier than the fronts, which is what his setup looks like to me (hard to tell though since he hasn't posted a full side profile). Thanks in advance.

275 in the rear will probably be too beefy/aggressive and you'll likely have rubbing issues.

^ This. He's lucky he's on springs because with coils.. boooy he gonna rub.

Answering the above question; his fronts aren't that stretched tbh. it's a 235/30 on 8.5 width. I have the same tire size on my fronts but I run a 20x10, also remember different tires stretch differently. So if you buy a hankook v12 it won't be the same stretch as a nankang (yes, even if they're the same tire size).

how did the 20 x10 affect your turning? i wan't to get that size in GTR rim's i found a set ($1,000 for all 4) off a totaled one but didn't jump on it cuz i wasn't sure how it would fit.
I'd be on standard height btw.

In my opinion, a 245/35 would do the job. [ 10.5" rears ]

On stock height, they would fit 100% no problems.

I'm looking at different wheels now.

20x8.5 Front 235/30/20
20x10 Rear ?

Would a 245/30/20 be a good match for the front's stretch?

[SanoSuKe]

I'm not really sure what kind of stretch you're going for so I can't answer that.

[BRicci]

And just go to any tire calc (http://www.discounttiredirect.com/direc ... reMath.jsp)
and put the tire size in there and look at the tire section width, that should help you out a bit. And just google pictures of stretches with those sizes and width you want, there should be some pictures that match exactly.
