I was thinking of a all-season set of tires mounted up for trips and etc. I think that I will look at the all-season run-flat tires on some nice 19" GT rims. I think that would make me feel more confortable on trips non-comp driving. I see now why some companys were doing the run-flats.

 

Get a trailer hitch & trailer for your spare tires!!

I have the tire inflator in my Roush hope I never have to use it, the spare tire "WILL NOT" fit over the big brake upgrades from Roush, Shelby, Ford etc

Torsen LSD differentials do NOT have friction type clutches in them just helical cut gears. So running dissimilar dia. tires (temporary spare) is not an issue with this style LSD from what I've read.

As far as a full size spare, read this thread I started a while back ...
https://themustangsource.com/f726/fu...-11-gt-487403/

The 2007-09 18" GT500 wheel should fit over 2012 Boss 302 front brakes (same 14" dia.). These are however 9.5" wide, so I did some searching on TireRack & DiscountTireDirect for narrower rims that will fit GT500/2011 Brembo GT ... well, D-T-D showed various 18x8" Drag DR-34 wheels ($150 each) that supposedly will fit over the Brembos.

A 225/50-18 tire will mount on an 8" wide wheel (no wider though) and it's 26.858" dia. MAY just fit down in the trunk well without deflating ... there are 29 choices in this size on T-R & 14 on D-T-D. This tire is only 0.06% smaller than the Boss/GT500 fronts & Brembo GT F/R (255/40-19 = 27.03" dia) and the SAME basic dia. as the Boss/GT500 rears (285/35-19 = 26.854" dia.), so there should never be a differential issue on cars with a std. T-Lok.

Doug, thanks for the excellent research on potential spare tire/wheel issues. After my car gets here I may take it to Discount Tire and just test fit a plain 225/50-18 into the trunk. If no fit issues, you have done the legwork to handle the spare issue.

 

whoops

 

I found a site that sells 17" x 4" compact spare wheels for 2010 Mustangs. Does anyone know if they will fit over the 2011+ GT rear brakes?

 

An UP-DATE, check out this thread ...

... this guy appears to have taken a chance on my "full-size" spare wheel & tire recommendation from D-T-D (post #24) to fit over the Brembo's.

He has not only found that it fits perfect over both front & rear BUT it even fits down in the spare well fully inflated to 35 PSI and protrudes above the trunk floor only 1.5" !!

Even better yet this 225/50-18 tire is only 0.06% smaller than the Boss/GT500 fronts & Brembo GT F/R (255/40-19 = 27.03" dia vs. 26.858") and the SAME basic dia. as the Boss/GT500 rears (285/35-19 = 26.854" dia.), so there should never be a differential issue on cars with a std. T-Lok when mounting it in back.

My plan:

1. Remove the inflate-a-tire can from the vehicle. Round-file.
2. Call wife and have her bring one of my stock Mustang GT wheels (the 2010's clear Brembos no prob) and the torque wrench to wherever I am with the flat. Smoke, and browse iPad in the meantime to find the best price on a replacement tire.
3. Wife arrives, grumbling. Change tire, head home, take wife to dinner to fix that "issue".

Easy. Lightweight, too!

 

May as well make her change the tire too, while you're at it; because face it, you're not getting any. lol

Seriously, the Torsen isn't an issue as said above it doesn't have any clutches. Personally I'm not getting a Boss but for long trips I'll likely pick up a normal GT spare. It won't clear my Brembos but it will clear the backs -- if I get a flat on the front I'll just put the spare on the back and put the back tire on the front.

 

Thanks for the great info Doug. Looks like a good way to go.

 

Which wheels?

These?

 

Can't tell from the pic there, but if that's the 19"x9" in the nickel finish, then yes.

 

They don't clear the Brembos (at least the 05-09 GT500 Brembos). Tried them on my wife's car and no bueno.

 

Hmm, my 19's are really close spec-wise to what comes on the Boss - I was pretty sure they would. We'll have to find out.

But if not, no worries, for I shall also have track wheels :-)

 

That's basically what I did the last time I had a flat tire. A couple of years ago I hit something in the road on the way to work at 10pm. Since I usually run without a spare tire in several of my cars in the summer and when I'm close to home, I didn't have a spare with me. I called my wife, she loaded an extra wheel/tire, my lightweight jack, cordless impact, torque wrench, and the kids in the car, drove 10 miles to where I was, I had the flat tire (the wheel was bent) changed in about 3 minutes, and I was on my way to work. The thought of no spare in some of the new Mustangs doesn't scare me off, and I have had a flat 200+ miles from home in the past.

I got a flat on my LS within 20 hours of having it. the kit is only good for showing you where the hole is. it was a crazy day on the side of I-75 in southern MI.

I was super lucky. My father in law saw me on the side of the road going the other way. He turned around, stopped to make sure I was ok, then ran and got a patch kit. I inflated the tire tire with the supplied pump.

 

I just purchased a 2013 GT and of course it comes only with the silly inflation kit. I also have 20" custom wheels. I obtained a full sized spare that fits into my well like a glove, and the rim will also fit over the front Brembo brake caliper. In addition, there is room under the rim to stash the inflation kit, plus a scissors jack and a lug wrench! And the floor covering of the trunk does not stick up!

I got a 19X8.5 DRG DR37 FB 73 rim and mounted a 225/45R-19XL tire. It is perfect! I need two different thinwall sockets for the lugs on the custom wheels and the spare rim. I now will not get stuck in the middle of nowhere away from cell reception waiting for someone from "The Hills Have Eyes" to find me and offer a hand.

 

Nice! Now let's see some pics of those yellow calipers!
