Had some km2's 35" installed on Friday. Drive it home and started to shake the steering wheel at 45mph. They were closed so i called them on Saturday to schedule an appointment for today. Since i had the bags installed they are telling me this is the best they can do as far as balancing these tires.

Anyone else have this issue?

Should i just go back to having weights installed?

 

Bags are the easy way out, I've balanced a lot of 35's. it takes along time because you geomatch the rim to the tires then balance them. Basically you take the heavy spot on the rim and match It to a light spot in the tire

 

I mounted 35" KM2's on Hutchinson Rock Monsters about 2 weeks ago and took them to my mechanic for balancing. He used around 12oz of weight on inside of rim on 2 of the 5. That was the max weight that Hutchinson recommended. I have minor shaking at 40-45mph, otherwise it rides very nice. Just spent 10 hours on the interstate and was good at 65-70mph.

 

Just had the tire shop balance the tires with weights instead of the bags and everything feels great at all speeds.

Not sure if I'll ever go with the bags again.
