why is my steering wheel trembling when I reach 50 mph?

yes we rotated the tires and it was worse. The car also veered hard to the right afterward. The other work was performed at the dealership, sears, cv joints at firstone

To many hands on it............figure out which place you trust most. IF switching tire location CHANGES the symptom/condition , then tires are suspect. What brand & model tire did you get?

Nitto Xtreme..unfortunately I do not have much of a selection bc my celica calls for 205/55/15 in which is considered an "oddball" tire

Check "tirerack.com" , search by tire size not vehicle ,select "all brands" .........Dunlop , Bridgestone , Khumo& Yokohama , have tires listed..........but , yeah , not to many.From my experience , the tire racks ratings are pretty reliable. Good luck.

Thx
