To find the low spot on a wheel you should run a dial indicator on the inner and outer beads. But the general rule of thumb seems to be that the red dots are placed where the valve stem goes. Sometimes you'll find other manufacturers will put red dots and yellow dots on the rims. Then the question is which dot do you pick???!!!

Are you having problems with just one or all of the tires when balancing? Of course don't rule out a bent wheel........
