When running hards tires (Hoosier D-55, D-70, 1600) or A.R. 56 & 70 or Goodyear G50.

1. What is the best dize blade to use for grooving?

2. We typically do 3 sipes per block on a wrs d55....is there a proven better # per block?

3. Typically on the rears we only go side to side on grooving and siping and on front go the entire circumference of tire.

Just trying to get some input on how others prepare their tires
