Should my spare match my new tire & rim size?

I'm currently bone stock. Going to get a full OME lift with 17" FN FXpro rims and 285/70/17 Cooper tires. My spare rim is whatever size came with the truck, and it has a 265/70/16 stock size tire.

Do most people get a matching spare rim? I don't plan on ever needing to use my spare, but with the new lift and shoes, is it going to be possible to even run it? Considering a brake upgrade as well.

 

Not worth it. The truck has differentials. It won't care if you have different size tire on it for a short while.

Trucks with ABS will throw a code, but won't hurt anything.

 

Great thank you, I did not want to buy an extra rim and tire.

Are people on TW interested in a set of four stock steel rims?

 

I don't think anybody plans on needing to use there spare but it happens. If you are going to be off road especially way out, its a good idea to have a full size spare. If not, you can probably limp down the road without one.

 

Think you meant to say open diff...

I'd suggest a full size wheel, overall.

The matching wheel (not rim) is an aesthetic choice really.

 

There will be many different opinions about this, but one option is to pick up a lightly used 265/75/16 C or E load tire and use it with the factory spare wheel. The thinking being that if you got a flat while off roading with your 285s, you may need something beefier than the stock P rated spare to limp home on.

 

When I'm crawling at the mall and get a flat, I will call AAA. I don't do too much gnarly offroading.

 

That is a full 2" difference in diameter and it could do serious damage to the truck if you put it in 4X4. For temporary use in 4X2 you could get by, but I'd much prefer something a little closer in size. You don't have to buy another rim. If you ask around most any tire store will swap you a used tire for your spare tire that fits on a 16" rim that will come very close to the overall diameter of the 285/70/17's. Very little or no cost to get a spare much closer to the size on your truck.

If the difference was less than 1" in diameter then I'd be OK with it. But still wouldn't operate in 4X4 except in an extreme situation.

 

Truck is 2wd. I will look into having a shop swap it

 

It all comes down to how far or how long you might need to drive on the spare.

 

From what I have read if you were going to keep the vehicle long enough to use up all the tire tread then having the 5th matching tire/ wheel will pay for itself if you were to do a 5 tire rotation. Statistically the added life will more than cover the cost of the 5th tire. This doesn’t factor in with the cost of the wheel though. Most probably wouldn’t do this just because it’s not convenient but I can tell you from experience that it’s not convenient having a spare tire that’s flat because it’s been ignored for the last 5 years.

 

Matching size spare is nice. Found my full size spare on offer up, $75. Not a matching wheel but pretty nice. Add a patch kit and air bottle to your list.

 

Yes get a matching size tire. You may be ok for a little while, but smaller on one side means that side is spinning faster than the other. Axles/diffs were not meant to operate that way. If you have 4wd and decide to use it you can really mess stuff up with mismatched tire sizes.

A used spare in the correct size is cheap enough insurance that you wont have to worry about.

 

I mean, you do you, but with a 33, most are going to tell you to get a full sized spare.

Wheel doesn't really matter, but the overall diameter should closely match.

Trucks are different from those little shoebox cars with donut spare tires. Higher center of gravity, more wheel travel, different steering geometry, etc...

Most 33s you can still fit in the stock location with minor modifications.
