(*) - The alpha numeric system is the older method for tire sizing (see right chart above). Back then, tires didn't get much bigger than MV85, which corresponds to a 150mm width.  Newer tires larger than 150mm will only carry the metric sizing designation.


How they work?

  • The beads when added to the inside of the tire will distribute themselves throughout the tire during motion to counter act the heavy spots.

 

Tire compatibility
    Good rule of thumb is to figure 1 ounce per 10-12 lbs of tire weight.
