Yeah, i kinda knew all that. It just seems like it's more of a constant bumpiness regarldess of which road i go on, possibly indicating mishaped wheels or tires. Not saying you're wrong, i was just hoping my new wheels wouldn't make me nausious. I did just decrease the air pressure from 40 psi (they put in) to 34 and it seemed to help a little. I'm going back to see if i can get some 245/35R20's instead. If i'd know a week ago what i know now about this stuff, i wouldn't have trusted an "expert" for anything.
