One thing about those stick-on wheel weights, I have yet to see a tire shop that actually cleans all of the old adhesive material off whenever they balance a tire so unless you’re standing there watching them balance your tire and actually make a mental note of where exactly and how many weights they put on your tire, there’s no way to tell that if you to go out there right now and look at the inside of your wheels and see if the sticky residue you find was from a weight that came off that they just put on or if that was from an old weight that didn’t get cleaned off.
Even though the brand new stock tires rode good and actually had pretty good traction, I knew that wouldn’t last long due to a previous experience so while they were still new, I got rid of them so that I could get a decent return out of them.
But yeah, you could also have an out of balance drive line, too. I would definitely start with the road force balancing because you’re not the only one to have this problem.
