I have 3 fairly new tires on my car (bought at the same time), I've put 5000 miles on them. I have 1 older tire with about 20k miles in the right rear. I was wondering if I should rotate them? The only problem is that the right rear tire is more worn than the 3 new ones of course, so I may have problems with traction in the winter time if I move the older tire up front. (Car is a FWD Buick). Do you guys think I should wait a few months until the snowy months have passed and rotate them then? By that point I'll have probably put 10k miles on the 3 new tires, and I don't want to wear them out prematurely.
