I have a tire that has failed on my pickup and I would like to know if using my mismatched spare would be ok? I have got a new Good Year Wrangler as my spare and the ones on my truck are all 6yr old Cooper Discoverer HT. I am looking to drive it through a Vermont winter and get 4 new tires next summer.

If I put that oddball on the rear, would that be ok, or just a bad idea to mismatch tires like that? This is on a regular cab, short bed stepside 4x4 pickup.
 
you can IF it's the same size tire and i would also measure the out side diameter some brands run bigger or smaller even thought they are the same size
 
My tire man tells me that the SIZE is very important on a 4X4, mixing tread and brand makes little difference. All four MUST be the same size, or excessive wear and/or not working will occur. Greg
 
If the tires are the same size, you should be OK in a pinch, but the whole winter isn't a pinch. 6 year old tires probably won't hold the road in snow and ice like new ones will either. May want to invest the money you want to spend next summer in some new tires now so you'll have a better chance of being around when summer comes. Good luck,

Actually, that spare has been mounted up underneith my truck and has gotten sprayed with roadsalt all these years, that spare is so rusted in that I couldn't get it out when I tried this last summer. I'm not even sure how good it is. I think it would be better off left as a spare.
 
same size and you'll be fine for a while...run the mis-matched pair on the rear, could create a pull on the front. Keep in mind- you'll be running around without a spare if you hang all winter. Next flat will be a road call!
 
Were the tires good enough that you were going to run them this winter? Take the spare and buy another Goodyear to match and put on front rims, take the poorest tire for the spare. Put the new tires on the front, that way you have best traction on the front when in 4 wheel drive....James
 
I bought a new tire that was different than my old one and it pulled bad to one side. Had to buy another new one like the new one I had and it drove fine.
 
I'd put it on the front. If the tires are 6 years old and showing their age, I'd do like the others are suggesting and atleast buy 3 more new tires to match the one that's a spare now, and keep the other one with the best tread as a spare.

Right now I've kinda got the opposite problem. I had 2 pairs of tires on my truck with good tread. One of the fronts got a slice between the sidewall and tread, so I put my mostly worn spare on. Still have most of that last set so I had one of the old ones put on and now it's my spare. Once the older tire gets worn too far I'll put the other one on.

It's not a 4x4 and it doesn't ride any different that I can tell.
