So I’m tire shopping and Michelin has new names for it’s Pilot Sport tires. This is the first that I’ve learned about a Michelin All Season 4 and a 4S. The All Season is a better value and is a 45K mile tire versus 30K for the 4S, although both will probably go half of that. They are both Y speed rated. Anyone know why the 4S costs more, and is it worth it? Or vice versa for the All Season 4?
