My 05 HL LTD was great. It was really smooth while driving at high speed. However, the factory installed Goodyear only lasted 25K.
We just had a set of 4 new Bridgestone Dueler H/L Alenza installed at Firestone and they were pushing for alignment. They even showed me the computer read out that the wheels are out of alignment. I eventually said "YES" and now the steering wheel is shaking at high speed.
They have rebalanced the tires twice already. Is this the problem of defect tires or the alignment?
