Product Description

Perfect for siping tires used in motorsports. Two handle design aids in cutting stability. No power source required or cords to manage. Tough billet aluminum body construction with nylon base. Uses easy to find standard utility knife blades sourced locally. Cuts up to six sipes with each pass of the tool. Depth of cut adjustable by loosening thumb screws and setting to desired depth. Maximize Your Tire’s Traction by Adding Grooves and Sipes If you race on dirt you know that track conditions change throughout race day and many will ask how to increase traction on tires. From a high grip surface that can be wet and slinging mud to a shiny black or even hard and dusty surface as the laps pile up and the sun goes down, tire traction can change dramatically. While there are different tire compounds you can choose from to aid in traction depending upon the track’s bite, one thing many experienced racers do is modify their dirt tires by adding grooves and sipes to the tread blocks. What is tire siping and grooving? Well, grooving is just that, cutting grooves in the tread where you are removing rubber, while siping is where you make a thin cut (like a razor blade) but no material is removed. These cuts can be made in various widths and directions to enhance traction and get the tire up to temperature faster but can also be used to increase a tire’s longevity by helping it run cooler too. It is all in how the tire is cut. Learning how to cut a tire with a tire groover and sipe your own tires is a bit of a black art, but a good racer will keep a logbook of modifications and can reflect on past track conditions to see what size groove and angle worked best previously. The same goes for tire siping. Often you can lean on a fellow racer for grooving and DIY tire siping advice or reach out to the tire manufacturer for suggestions on how its tire products react to certain grooving and siping cuts

5.0 out of 5 stars Does the job

The Speedway tire super basically pays for itself the first time that you use it. Have some extra utility blades on hand. Don't fool yourself, it is a fair amount of work, especially on larger tires.

What a difference. I made 1/8 deep cuts in the lugs on my BF Goodrich rugged terrain TA's on my full size truck and they work good in every type of weather now. They used to slip in rain and slush. Not no more!
