Yes from a full set... they are all identical and all matching tires. Lightly used on a rear wheel drive BMW, so naturally, 2 (the rears) are worn slightly different then the fronts.

The set is fully square, meaning all identical size, so you could put the 2 with 99% on the rears.. or continue to use them on the front.

By tirerack recommending them to be installed as a full set of 4... they mean you should not run 2 winter tires and 2 summer tires together.
