Upgrade to 265/70/17, spare tire question

Considering the stock tire size is 265/65/17 and my new tires will be 265/70/17, I'll have to get a new spare tire. Is it necessary to get the same tire for the spare that I'm putting on the other 4 wheels? Or can I get something of the same size in a different (and probably cheaper) brand that will serve as the spare.

My main concern is that 2 different tires (i.e. BFG A/T KOs vs Destination A/T) with 265/70/17 measurements might not be exactly the same diameter. I realize this is just how things are, but I dont know if having a different spare will potentially damage things should I ever need to put it on.

Thanks for any input.

 

It shouldnt be an issue, as long as you dont drive on the spare more than you have to. In my old car the spare was a little shorter than the rest, and thats what the tire place explianed to me.
Worst case, get a used tire for your spare thats comparable in size if you dont want to go that route.

 

Well I'll be getting a new spare with the same tire specs (265/70/17) opposed to using the factor 265/65/17 spare. But the only thing I was concerned about is the overall measurements differences between different tire brand/models that are in the same tire size category.

 

i agree... Look for a used tire that is in good shape for the spare and same size as the new. Save some cash.

Even if you had to use the spare, you arent going to be putting a ton of miles on it before you get the good tire replaced.

What brand you going with? Where you getting them?

 

I'm looking pretty hard at the GoodYear Wrangler Dura Tracs, getting the from a local Firestone shop. I've given them a lot of my business in the past and they are giving me a pretty good deal. They're one Firestone shop I actually somewhat trust (key word being somewhat).

My only hesitation about the Dura Tracs is what kind of wear I'll get out of them. Hopefully they won't be gone in 20,000 miles. My other option was the BFG A/T KO, but I like the look of the Dura Tracs much better.
