Installation Details

Installation Tips

Install the head and set the blade to the depth of cut needed before plugging in the groover
Plug the groover in and allow it to warm up for five minutes before you start grooving; our tabletop tire grooving iron stand is suggested for warm up and cool down
Always store tool facing up/handle down in a vertical position while in use to minimize temperature transfer to the handle
Monitor the temperature of the tool and unplug it as needed to regulate the temperature

Tire Grooving Tips

Sanding the mold nubs off the tread before grooving or siping is suggested if the nubs are large; a tire grinder with a 60-grit 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
Complex tread designs can be marked out with a tire marking paint pen or paint stick

Circle Track specific Grooving and Siping Tips

Tire Grooving

Grooves around the circumference of the tire will add side bite and help cool the tire
Grooves across the tread will add forward bite and help warm up the tire
Rear tire grooves and sipes across the tread typically work best when straight across the tread (90 degrees to the circumferential grooves)
Front tire grooves and sipes across the tread typically work better at a slight angle and when viewed from the top of the right front tire the grooves will angle from right front to left rear

Tire Siping

Sipes have a similar effect as grooves and are primarily used to warm up the tire
Sipes around the circumference do not provide much if any cooling effect since they are not open for air to flow through like grooves are
1/8-inch to 3/16-inch sipe depth works well for most tires.
Adding more sipes which are closer together will increase the tire temperature and will add grip as long as the tire is not overheated
If a tire is overheated and blisters the sipes need to be spaced further apart and possibly a shallower depth of cut should be used
More sipes are typically used on front tires to help them heat up and less sipes on rear tires, especially the right rear

Bought this for my speedway tire groover, 2 weeks later the tire groover died. They don't have anyway of replacing the groover it's self. The head it's self broke after only doing about 20 tires.
