And I must say that the Blizzak LM-60s work really well in the snow. HOWEVER, I was going to install them myself in my driveway and I even bought the torque wrench AZ suggested, but after I took off the first wheel I found out that there is a 6th screw that needed to be removed, so I had to bring my car to Nissan to have the job done. They had to grind down all 4 winter wheels so they would fit over the 4th screw, and it ended up costing me an hour's worth of installation ($97). If you take off the sport wheels, you will see that the winter wheels don't fit right, so you either have to grind them down yourself or bring them to the dealership to have it done. Ugh...
