This will be my third winter with Pirelli Sottozero 240. All stock sizes. I'm having the fronts replaced with Blizzaks because I noticed a bulge on the R front last week. The tires came in today and will be put on Tuesday. After driving on the original sotto's for 1 week I inspected all tires carefully again this evening. A second bulge has formed on the R front tire and now there is a noticeable bulge forming on the L front. The rears look fine other than this will be their last winter.
