Tire Balancing Products
So I have some 30x9.5r15 tires that have not been balance friendly lately, but still have 20k+ miles of tread left. So the shakes have been getting to me and I finally decided to try these.
While the shake is not completely gone, it is much less noticeable. Also, when you hit a bump and the tire's balance changes, you can feel it go crazy for a second as the beads try to balance the tire as its profile changes from the bump, and then back to its original shape.
Also, PLEASE NOTE: This will only fix tire imbalance issues, not Death Wobble due to suspension or steering issues.
I used 6oz per tire of the original beads that go down the valve stem. It was a pain in the A$$, but using an electric tooth brush or a dremel to create vibrations helps them flow through the valve stem easier.
