One Flat Turns to Four

[Steve Mills]

I regularly buy 2 and rotate the leftover to a full size spare without having the new tires shaved, and run the new and old on separate axles, generally with the new in the front because it takes the bulk of the load. Been doing it for the last 15+ years I've been daily driving /S cars and never had a problem.
