I rotated them every 5000 at the dealer with oil changes, they did the pressure 35 psi and my sensor has never gone off, they are at a 6 per the dealer and discount tire, a bit more wear on the outside they said at discount, never had the alignment checked never knew I needed to (maybe dumb on my part) never hit or scraped curbs, was told before that ford put softer tires on these for a better ride and these tires don't have a mileage guarantee at all.
