I use Pirelli Snowsport 210 as winter tires for my 2004 CLK320 Coupe. I just replaced both rear tires last year. When I changed my tires this summer, I noticed that the rear right tire was worn quite bad due to a bad alignment. The other 3 tires were very good.
Since I travel to Montreal quite often, I need good winter tires. While I was looking for the Pirelli 210, I was told that this tires had been discontinued. I was suggested to buy the Pirelli 210 Sottozero. I did my research and found that these 210 Sottozero are not too good.
I did call around and some stores said they were able to order the Snowsport 210 for me. In my mind, since these tires have been discontinued, I would be getting some old stock. Do you see any problem?
Because of the sizes (F: 205-55-16, R:225-50-16), I really have not much choices. The other choices are Blizzak WS-60 and Michelin X-Ice. Should I just replace the 2 rear tires and keep the Snowsport 210 in front?
