I have a vibration at slow speeds 5-25 mph seems to go away from there. It has 20k and I do see a dimple on the sidewall ofa couple of thetires that runsup tothe tread. I am wondering if that could be the cause. The harder you accelerate and into turns at that speed you can feel it. Thanks for any input.

 

is your air presser set at 35 or close check for worn tire on the front too. hit a pot hole bent rim? alan
