I just bought new tires for my 04 pontiac Gr Prix. But i can feel a lot of roughness when i drive it, you can feel the texture of the road even on a new paved and smooth road. Its harsh. The steering wheel dosent vibrate but you can feel is not a smooth ride. It was not like that before.
Just wondering is something wrong with the tires? maybe i got a bad tire, or underinflated. Right now is at 30psi, the recommended pressure.
