Is a larger spare tire ok?

SoCalChris · April 6, 2006

With less than 1,600 miles on my new truck, I managed to blow one of the tires. It wasn't able to be fixed, so I had the full size spare mounted where the blown tire was at.

Now, I don't have a spare, and all of the tire stores around here don't sell the correct tire size for anything less than $120, plus mounting. One place has an used tire I could buy for $30, but it is slightly larger. Would this be a problem?

Current tire size:

245/70 17

Used tire size

265/70 17

I don't see it being a problem, since most cars come with those ridiculous "donut spares", but I just wanted to make sure I wouldn't hurt anything.

And why doesn't Chevy offer a roadhazard program on the tires that come with new vehicles???

If a 4x4, it is critical to keep the same tire size. Any difference in diameter can cause binding and breakage in 4/4 mode or rear diff locking situations. Different diameters also mess with abs programming and can trigger abs when driving normally. It really depends on the difference between the 2 tires.

I believe the donut spares are the same diameter as the original tires so they don't cause a problem. When I switched from P265/70R16 to LT265/75R16 tires, I replaced the spare for this reason.

Thanks.

The truck is a 2 wheel drive, non-locking differential.

Have you checked with your dealer? They will replace it in first year if there any good. I have had 3 replaced one a runflat.

I agree I believe the tires are covered by the Mfg.

I remember seeing the Bridgestone flyer in my pack of information in the glove box but have not read it yet

*I also had a run flat go out on my C6 and it was replaced at no charge by Goodyear without an issue.

My dealer is a few hours away, so it wouldn't be worth driving there and back for a tire. I checked with the local dealer here in town, they wouldn't do anything about it, except offer to sell me a new tire.

One of the places I called earlier called me back, they found a correct size used tire after I had originally talked to them. I'm going to go get that one.

Thanks for everyone's advice.

You mean there isnt a dealer closer than two hours away? Any dealer can replace it.

It's my belief that the tires are not covered by the GM warranty, but but by the tire manufacturer. I had a Blow-Out on my '06 GMC (245/70/17) and General Tire has no Road Hazard warranty. I took it to Discount Tire, and they wouldn't touch it. I took it to another Discount tire (were I know someone) and they prorated it for me. Cost me a Lot less than a new tire. Guess what kind of tire I will never buy again - You got it - Generals.

As they add goes sooner or later you'll own Generals, well I own them, but never again.

Actually though, they are not a bad handling truck tire, but I will never buy another tire that doesn't have a road hazard warranty.

There's a dealer about 30 minutes from my home, and another one about 5 minutes from my work. Neither of them would replace the tire for free though, since it wasn't under warranty, and I didn't purchase the truck from them. The dealer I purchased from offers road hazard on the tires, but only if you get your oil changed there. I believe that they offer road hazard coverage for 3,500 miles after your oil change. They're pretty far from me though, and I had just changed the oil on my own, 2 days before the blowout, so that wasn't really a good option for me.
