I have replaced the oem tires on 2 x3's with Scopion STR's. The origional equipment tires lasted: Michelins 38K and Pirelli's 45K neither were at or below the wear bars, but as we live in snowy climates we replace the tires for the winter when they are close to the bars 1/2 mm. The scops SUV tires seem to have better winter traction than the Michelins which are passenger car tires. Tire Rack currently has the Pirelli's on sale.
