Average miles to expect from OEM tires..

Shawa

I personally got 28k off them, but shouldve changed them around 24. I drive spirited and here and there spin the tires and have fun. My fronts went way before the rears tho because of hard cornering I guess.
As far as the winter goes, they're horrible lol. Got caught in a snow storm one day and slid the whole way home, a 45 min drive took me about 3 hours.
Get some blizzaks or avoid the bad weather haha. In wet they're great no complains, just snow.
