Thank you for the responses. I've recently learned that Michelin is coming out with a Primacy replacement tire in April called the Premier A/S, so think I'll wait and consider the new tire, as well. Anyone familiar with this one? Also, has anyone had any experience with the Pirelli Cinturato P7 All Season Plus tire and/or Continental PureContact w/EcoPlus Technology 97V on an LS 430? Both are highly rated and ahead of the Primacy on Tire Rack. Thanks, again.
