I don't know, just seems like an unnecessary additional expense. [/B]
It would save me the cost of a tire but thats not big deal . I don't rotate my spare. I still got 48k on my Revos and probably could run them another 5k in summer and not going off road at all. Then they would be cooked. They have wore perfect , so I'm ok with that.
All the tires I'm looking at are all in the ballpark of the same price range , so just got to pick the right one.
