I have two different pairs of all-season tires: one pair that has been driven for about 20,000 miles, another pair from a different manufacturer that is new and that has been driven for maybe 1,000 miles. The older tires are noticeably more worn than the newer tires.
When my car shop replaced the winter tires by the all-season tires this week, I asked them to mount the newer pair at the rear of the car. The person who took the order said that I shouldn’t worry about it because they would measure the tires and rotate them accordingly. When I got the car, the new and old tires were installed diagonally across from each other: front left old, front right new, rear left new, rear right old.
Is this okay or should I go back to the shop?
