I was wondering if there is any use carrrying around a spare tire that is the wrong size? I have 285's on my truck now and the spare tire is still the stock 265, will it mess up my truck if I use the smaller tire? if so I'm gonna ditch the extra weight. BTW i have a g80 if that matters?

 

Bump, Merry X-Mas

 

It shouldn't matter and won't hurt anything but your pride. My truck came with 20" wheels and a 16" spare. Hopefully I will never need to use it.

 

Thanks, thats reasurring I was worried about the differnent size tires spinning at different speeds and messing up my rear end.

 

yeah you'll be fine. just dont leave it on there forever

 

The scenario in which this would be a problem is when the tire height (not necesarily the width) is a different size.

As for having different size wheels: I plan on ordering 5 20" wheels when I eventually get my wheels because I will be upgrading the brakes that will require larger than a 16" wheel - and I don't want to get stuck. . . anywhere.

 

I like that! That would force me to get rid of that oddball wheel.

 

i got 285s on my 99 z71 and a spare tire of 265

 

you dont want 2 different hieght tires on the rear especially if you have some type of locking or posi device....now to make ur desion harder after i just made it easier, if u have a flat on the back tires move a front to the rear and put ur spare up front.

 

What I do.
