Given the price, you can take, at the time of purchase 1 year. Some pros: Quiet. In principle, I don’t hear noise from rubber, bumps, bumps in the road, the pit works out well, grip on wet and dry pavement. Cons below: Cannot be stored at temp. less than -10 deg. Less than +7 degrees dubeyut.
I wanted to add some photos to my review to visually showcase my experience.
