[Beginner]

When I said one shop in a hundred I included all RV dealerships, commercial tire shops, the Firestone dealers at the mall and the local mom and pop tire dealers.
When you say ballance the brake drums they look at you like you are from a different planet. Then you run into this old guy who just gets this all knowing grin and tells you "we havent done that in 30 years or more. Dosen't mean they don't need it, just no body bothers because of the additional cost."
I could not afford the Centramatics last year because of the tire/wheel upgrade so I used the ballancing sand(sand bags). It was installed through the valve stem(all valve stems are the same) with a little machine they had and the special Schrader valves (cost me $1.00 each) were installed. The bags were I think $5.00 each.
