I put the Blizzaks on the wife's Fusion tonight, and had a question for the tire experts on here. The tires are about 3 years old, but in pretty good shape. They are WS 70's I believe, and are directional. Looking at the tread, it was fairly obvious which tires were on the front last year, as there was a noticeable difference between the front and rear tread depth. My question is this: Should the tire with more tread go on the front or the back? I know that when you get only two new tires you are supposed to mount them on the back, to prevent fishtailing/oversteer. I also know that tires generally wear faster when they are on the front axle. So, should I put the tires with more tread remaining on the back to give better stability, or on the front to try to even out the tread wear?
