Prepare Your Tires Prior to Grooving. Sanding the mold nubs off the tread before grooving or siping is suggested if the nubs are large; a tire grinder with a 60grit sanding pad works well for this. Most tires are easier to groove or sipe with the tire mounted and inflated to normal pressures; this is especially true with thin wall racing tires.

Tire Feathering. Tire feathering is a tire wear pattern when the treads on a tire are rounded or lower on one side and higher with shaper edges on the other. This occurs because the tire is worn down at an angle and is an indicator of a misaligned toe angle. Vehicles are very sensitive to even minor changes in toe angle and a good alignment ...

There is a large gap between the tip speed and power intensity of the lowspeed vertical mills and the highspeed horizontal mills. The VXP mill bridges the gap between highspeed and lowspeed mills. The VXPmills are designed for fine and ultra fine grinding applications. In practice, the mill performs best when the feed has a normal distribution.
