Changing Wheels Size Up To 20 Inch

[opus8844]

So I put Factory 20 in wheels on my suburban that had 17 wheels what do I do about spare under the truck it is still a 17 inch

 

what do the trucks with 20 inch wheels have on them??

[Majorleaguebass]

they usually have a 18" or 17" spare wheel....

[gmcierra]

as long as the O/D of the spare tire is the same as the tires on the 20's.

Yep. My 2006 Sierra came with factory 20" wheels and just has the regular 17" steel-and-rust rim for the spare.

[Zembonez]

Same here. 17 inch steelie on mine.

that's not really all that important either, as long as you have open diffs and don't drive a long way with your spare on.
