2008-2013 Cadillac CTS General Discussion Discussion, Spare Donut Tire in Cadillac CTS Second Generation Forum - 2008-2013; I want to get a spare donut tire for my 2011 CTS and the best price ($272) was from "GMPartscenter.net". ...
I want to get a spare donut tire for my 2011 CTS and the best price ($272) was from "GMPartscenter.net". Has anyone ever purchased from them? The tire comes not mounted on the rim. I expect that a tire store can do the mounting. My Cadillac dealer wanted over $430. Any other suggestions on where to get the spare. I tried salvage yards but they had nothing.
My dealer was nice enough to match the gmpartsdirect.com price when I bought my car. You might print the online price and see if your dealer can come close. (Even if their price is still more, it might equal out if you can avoid paying shipping.) Mine came unmounted, as you described, but the dealer didn't have a mounting machine, so they sent me home with it the way it shipped. I had to take all the individual parts out of the huge box as it wouldn't fit in my trunk.
I took everything to a Les Schwab tire shop that's near my house expecting to pay for the mounting, but they kindly took care of it for me at no charge. Their customer service was excellent; if you have one of their shops nearby, I'd recommend going there.
In 1998, I bought a new Jaguar XK8 and to my surprise, it had a full size spare and not just any spare, but an exact copy of the tyres and wheels on the car. The salesperson explained that I was buying a car with a long racing heritage and it simply would not do to be in a race without being ready to change a flat tyre and get back in the race. In 2000, Jaguar changed to a mini-spare. This time the salesperson explained the change was three-fold. One, he said, Jaguar had lost confidence in owners to follow the owner’s manual and rotate out the spare during tyre normal rotations. This left tyres in the trunk for what might be decades. As these are Z rated tyres, neither Pirelli nor Jaguar wanted anyone to "get back in the race" with a tyre that appeared new but in fact was too old to be safe at 175mph. Two, a mini-spare allowed them to put different size tyres on the front and rear, which they did in 2000. And three, it saved weight and lots of it. Besides, how often are you going to need to put on the spare and then still finish the race?
A donut spare tire is a compact spare tire. It takes up less room than the full wheel / tire combination and is intended for limited use and limited speed. I would say that is what you (and many of us) have.
