Good morning everybody.
Got a quick question. I am now running 285/70 17's on Hummer H2 wheels but am kind of curious what others who are running larger tires are doing for a spare. I looked under the rear of my truck to see if a larger tire would fit but not sure whether one would or not. Would it be ok to run my existing spare on the truck, from what I understand that is not a good idea especially with the G80 locker and just the additional wear and tear it puts on the differential by running with 2 different sized tires.
I guess I should have thought about this before I decided to put the larger tires on. One of the big problems is that if you happen to have a blow out with these 285's they are not all that common of a tire and could be hard to find.
I guess I could always mount a 285/75 16 on my spare and be able to run with that. Crowning would not be an issue because it would hardly ever get used.
Any oppinions?
