Tire Grinding Cups
Currently we only have a few of the Angled Grinding Cups left. This is something MWSC made for sharpening LawnTec Tires. When we run out these will no longer be available. We have decide to no longer carry any tire grinding items since we no longer carry rear tires.
You can purchase the grinding cups and discs from M.E. Miller Tire, they also sell rear tires of many varieties.
Use the disc to relieve the top of the lug, the cup to sharpen the front of the lug (on Carlisle or Firestones), and the Angled Cup (for chevron lug tires) to hook the front of the lug forward for a more aggressive bite. Grit rating is similar to sandpaper ratings. The larger the number the finer and smoother finish. These will work on an angle grinder with a 5/8" arbor
