I went with the inflator. Reason: We live in a major metro area and it's suicide to change a tire on the side of the road. If my wife has a problem with a tire, all she has to do is call and I'll bring one of other season wheels, a real jack, and a battery impact and change it after she drives to the next exit. Over the last few years, I have found it impossible to(long term) successfully repair these "modern", ultra low profile tires- no matter where they are damaged, so (to me)- what difference does it make if you drive on it? IMHO, I consider it to be junk anyways. As a bonus, in the mean time she has a truly righteous storage are in the back after I remove the inflator.

 

There is a TV commercial which shows a young lady changing her tire in the rain, finally a man walks into view...her father. He explains that he was teaching his daughter to be self-reliant. I think that everyone should have the choice to wait for help or change the tire and get out of there. My new Mustang will be ordered with the spare.

 

Joey - you gotta get your hands dirty sometimes. I cringe at the thought of having my car hanging from the boom of a tow truck.

 

I recently spoke to customer service at Ford who advises me that none of the Ford spare tire wheels will fit over the Brembo brakes on the 2015 Eco Boost Mustangs with Performance Packs. Further, he says no spare tire wheels for that application will be available from Ford in the near future.

I guess we will need to wait until one of the aftermarket suppliers provides one.

 

Aftermarket wheels are already available....make sure to get the correct wheel nuts as well.

 

I ordered mine with the spare. It was one of the contributing factors to me ordering in the first place; none of the Mustangs on the lot had the spare package.

 

I have Brembos on my '13 GT. No spare and inflator that I hope to never use. I put a jack and plug kit in the trunk to fix punctures, knowing sidewall cuts mean tire is trash. I may get a spare anyway. If the front goes flat, put spare on rear and move the good rear tire to the front. Requires two tire changes, but the tire sensor won't get damaged.

 

I put a jack and breaker bar in my trunk too. I'll pick up a plug kit. Thanks for the great idea. I do have a fifth brembo wheel. I put it in my trunk during long trips.

 

I remember reading about this problem in the past. One suggestion was to have the spare, put it on the rear wheel and put that tire and wheel on the flat front, with the Brembo brakes.

Of course the spare will work as usual on either rear wheel, if they are flat.

A little extra work if the front is involved, but peace of mind if you are driving in rural areas with limited cell service or on a vacation trip in an out of the way area.

EDIT: Sorry, I missed the post above stating the same thing.

 

What about the difference in diameter if you put the spare in back? I looked at the diameter of the p155/60r18 spare and it is 25.3, 2.4 inches less than the pp 275/40r19. Will this cause a problem with the rear end?

 

interesting, my PP convertible will be here soon and I'm going to pick up a spare. So the 18" spare from Ford will fit on either rear wheel even with the brembo brakes?
