Spare Tire Size

Got a stupid question - if I have tires larger than stock (275/70R18 or 285/70R18) what should I do regarding the spare? Is it "ok" to drive on a spare that is a different size (stock) for limited miles until I can get the damaged tire fixed/replaced? Thanks and sorry for the stupid question.

 

Hey Sean think I started this thread a while back not sure if u or someone else replied I got 35 1250 20 what's closest that can fit in spare wheel well I don't care about trimming

 

I have a 35" tire on my spare. Well it's like 34.6".

 

I'm a big believer in having a matching spare and doing five tire rotations. The spare tire will eventually dry rot and need to be replaced anyway, so why not get some use out of it? With a matching spare I can get off the trail in relative confidence compared to having a smaller tire that may be a street tire as well and not worry about any weird handling characteristics at normal highway speeds.

 

Are you doing a five tire rotation with tpms? When it’s time to get new tires I’m going to jump up a size and I want to find a matching wheel for a 5 rotation. I’d like tpms to work if possible.

 

Did you have to do anything special to make it fit underneath?

 

The TPMS for 2015 is only for 4 sensors. To do 5 tire rotation I would have to reprogram at every rotation. I’m pretty sure it’s the same for 2016, 17, & 18. I do have a matching rim and identical size tire for the spare.

 

Did this ever get answered and is it under the truck where the normal spare is located?

 

Pretty sure you have to remove one or both of the two tires tabs that are spot welding under there to fit a 35 without deforming it.

I’ll be exploring this option soon myself. After I get my ssbuilt front bumper I’m going up to 35s

 

Would like to find out also. I have a spare 285/70/18 that I haven’t tried putting in the spare wheel well. I still have the original spare there,

 

Too damn big, thats how big. Yeah, I need to get on Keto.

 

Thanks! I should be installing my new bumper this month. I currently have 285/75/17's which is almost a 34. I will end up finding a tear off of 285/70/18 to use as a spare since that will get me real close to what I have on for shoes. Please update us with your findings.

 

I have the same size wheel and tire combo and that’s what I did. I went with a 285/70/18 for the steel spare since it’s roughly the same diameter as 285/75/17. I would’ve liked having the exact same wheel and tire as a spare, but I cheaped out.

Mine’s a 2015. I hadn’t thought about the TPMS issues some have mentioned on here.
