Spare Tire question.

[ctluba]

I just mounted 285s on my H3 and did not get a 5th one for the spare. I still have the 265 mounted on the spare and plan to get the 285 on that next month. If I get a flat tomorrow can I use the 265 to get home or would that cause damage?

How far and how fast do you estimate traveling that way?

Based upon info I gathered I plan to travel 0 miles at 0 miles per hour. I was told it would not be a good idea at all and would cause damage. I will just mount the larger spare. If I get a flat before then I call tow!!!!!

That correct. If you didn't your rig would be unbalanced and could be damaged dependent on variables.

Interesting. I was wondering the same thing if I go to 285's on my next set of tires.

that is interesting... Maybe my Hummer dealer is dumb, but when I was ordering my 285's (33") from them while ago, they suggested to keep the 265 (32") as a spare. I rejected the idea and got all 5 the same size, however I noticed the dealer actually sells some of their H3s with non-matching/smaller tire as a spare. I saw at least one H3 on the lot with four 285's mounted and 265 spare.

My guess is that slightly smaller (let say 1" difference?) spare is OK as long as one doesn't have to drive too far or for extended period of time?
