15x11 rears?

[STOCK GT]

Hello,

Has anyone tried to test fit or had any success with fitting a 15x11 rear wheel?

Weld only has 15x10's in our fitment for the 2005-14 mustangs with stock brakes.

i'm guessing a 15x11 with a 8 or 8.5 backspace would clear but would have a slight poke or sit dead flush with the outer fender well?

Any feedback or info on this would be appreciated.

Thanks

I don't think I've ever seen a 15x11 wheel. Is there a reason you need something that big? You're only going to slow yourself down with anything bigger than a 15x8

I've seen 15x11 and 15x12....on a miata.

search psfracer's posts/thread, IIRC he went bigger, however he did move suspension to get it to fit

Not true at all. The fastest small tire guys in the country run 15x10 or 15x12" with 26x8.5 tires and 275's

YEA, but with how much power??? 1500? 1700???

8.5 limited guys make 8-900whp outlaw makes 11-1500 then x275 can make 2k plus, but to say anything bigger than 8" will slow you down is just wrong. A properly sized rim to fit the tire for optimal contact patch is what the user should be after. It will show in the 60' and tire life.

I have 11" on mine looking for pics

this was with a10.5 slick

11" WHEELS????

Not tire size he's asking about

 

[King Dingaling]

Once again these are 11" wheels and I have a set of 12" with 275DR and they are a bit too large for the wheel well. Still some would run those as well.
Looking for that pic as well.

275 on a 12" wheel

the 12 is a bit too wide but then again I like them to squat on launch. This is a closer look at the the 275R+DR on the 12". I no longer run them and just run my 11"

 

[Mr. Q]

Nice setup, what did you have to modify to get the 11" wheels to fit?

 

[BruceH]

An 11" wheel for 275/60/15? Is that right? Why not 15x7 or 8? Do you have to screw them in so they don't spin on the wheel?

You don't use rim screws with radials. Either beadlocks, or Permatex Hi-tack on the bead, when you mount them. We run a 12" wide wheel in x275. That's the correct width for a maximum-effort 275 combo. Anything less than a 10" wheel is giving up contact patch and sidewall control.

So a wide wheel is part of what it takes to make the 275 perform as well as it does? Thanks for the info.

I meant at his power level. A 275 whp car doesn't need a 15x10

I'm sure he could get away with a 26x8.5, or a 235 drag radial. Guys have been 4.70s in the 1/8th on both. But guess what? They run them both on a 15x10" wheel. I don't know why you're so opposed to simply running the correct size wheel, for the given tire, especially when it fits the car without any cutting. There's nothing but benefit to the larger wheel. You get a better contact patch from the tire and better sidewall control. Both are advantages at every portion of a pass.

So the wider the better huh? I'll have to remember that.

Well, to a point, yes. When outlaw 8.5 started, a few guys were trying to stretch them out on a 12" wheel. IF (and it was a big if) you could get them to seat, it just looked ridiculous and didn't show any performance improvement. Likewise, a few people tried stretching a 275 out on 14" wide wheels. Same result: nightmare to mount (even with beadlocks) and no performance improvement. So there is such a thing as "too wide".

 

[King Dingaling]

My rear is narrowed 2.5" on each side but that was because I wanted a deep dish look so you don't need to narrow to fit 11" or even 12" but watch your back spacing.

I have my wheels drilled for wheel studs but that was for slicks. I don't run studs for radials.
And yes the wide rim does help a bunch with contact patch. You will even see wear on tire and they are even.

I don't disagree at all that a 275 on a 15x10 is a better idea for bigger power cars, but for someone like him, why? With a 15x8, he won't have to cut his sway bar bracket, and he'll save himself some money. I'm going to be putting the 275 ET Pro on a 15x10, but its a 700 whp gt500. Much more power and much more weight.
