I recently bought my wife a pre owned 2005 RX330. It has the optional 18" wheels with 235x55x18 Michelin MXV s8 tires. I have read terrible reviews of these tires in almost every category. I want to replace them with the best choice for all around capability. It seems the number one choice is the Bridgstone Dueler H/L Alenza,which for the most part has gotten great reviews. I have read a handful of comments though that this tire flat spots after sitting overnight, and the that several sets could not be balanced. I would like to hear some feedback from Lexus only owners that have bought this tire. Your comments will be appreciated. I have found that the choices are limited by this tire size. Other then looks,what is the advantage to these optional 18" wheels and tire on the RX330?
