yep, i had 205's on my sidekick when i bought it and swapped out to some 235's and the guys at the tire shop put them at 35 psi, drove like a rock. checked the door sticker and it was suppose to be down at 23 psi. aired them down and man, rode like silk.
got a family member with a BONE stock kick with 205's on it, they were noticing the ruff ride and i swapped my 235's on to there truck, they said it was night and day, way smoother.
