I have been experiencing some high speed front end shake or wobble lately that I did not have before. It is fine up to about 100 mph then I notice the shake or wobble. The front tire looks fine with no visible damage or wear. I am currently running the Avon Venoms front and back. The back is starting to show signs of wear but not the front. Has anyone else experienced this? I wouldn't think that I need to get my front tire re-balanced but ??? Does anyone else have their tires re-balanced during the life of your tires??? My other option is just replace both tires and be done with it.
