I replaced Michelin 255/55 R19 11H 4x4 Synchromes with Michelin P255/55R 19XL Tour Latitude 111V HPs and I don't like the ride. They set the pressure @ 36F/44R and the ride is so tight that I feel the road more than I did with my old tires. They also look smaller, but that could just be me. Did I allow them to put on the wrong tires or do I need to adjust the tire pressure? I spent close to 1400.00 to have these tires put on and I'm pretty sure they won't allow me to return them

Any suggestions?
