I just put on my winter wheels for this year. They're getting near the wear bars, but I think I might be able to get another season out of them.
This will be the forth season for my Pirelli's.
How many seasons should winter tires last?
I think 4 seasons is pretty good, I'm very diligent with making sure I rotate them properly from year to year.
I use these tire storage tags to keep organized. They're from tire-tags.com if anyone is interested.
