Looking for a wheel balancer that will work with mt wheels and tires. One that works with 40 series as well would be a major bonus. All I seem to be able to find are for truggy tires and Im worried that they wont work with mt wheels. Any suggestions would be great, and if you already own one, even better so that I know it'll work.

I use a truck with the driveshaft removed on one wheel. Works quite well. I have an old stub shaft seperated at the outer u-joint for mounting the wheel.
