So finally got new tires ended up with yokohama g015 AT and they ride well. A lot of my vibration went away however at 70 to 75bmph I am getting a slight vibration through the body and into my seat. At 65 to 70 I feel it in the wheel abut around 75 it leaves the steering wheel and I feel the vibration in my seat. I'm thinking ujoints maybe?? Any recommendations would be helpful.
