On the street do they spin a little then grab and go or is it more like I can roast them if I want. Did you drive any in the rain? I only drive 5-10k a year. I swap all seasons in the winter and summer tires obviously in the summer. My work issues me a car I drive everyday so the GP doesn't get a lot of miles. Im not too concerned about lifespan. My tires rot out before wear out. But I hate to spend a bunch on tires to swap out and get only a little improvement in traction.
