The reason I ask is I just installed a set on my 2000, and the ride is rather lumpy at 45-50 mph. It gets better at 55-60, but especially at 45 it feels like the rear tire is filled with cement. I even broke it down, re-seated it and re-balanced it, no change.
I noticed the tires are four ply tread and sidewalls-the rear nylon and the front polyester. Could that explain the really harsh ride? TIA
