rozapaul, I had this early this year when I put new tires on my truck.. GOSh it was awful to drive, Worried me to death that I had screwed up front end. Took back to tire guy and he lowered the pressure down to 75psi per tire on the back and 70psi on the front. Told me I was good to go! really??? you know what he was right once I drove this set up the truck felt a lot better and handled like I was used to it. He told me the new tire depth allowed the tire to ride and flex on the thread tops making it squirrely feeling.. This past trip I pulled 200 miles one handed on the wheel until i got around others vehicles.The guy sells me all my tires and has for 20 years.. straight shooter when it comes to tires front end work, brakes and shocks, etc.
JMHO
