Depends on your intentions with it. Overall, the PSS or PS4's is a much better tire but cost a lot more. My buddy has them and he loves them. Overall a good tire for the price.
Btw, if you or know anyone that need the stock 275/35/20 runflats, let me know I'm selling the two rears for a real good price. 85-90% thread
