Title: Tires: sipering and grooving
Post by: CrewChief6 on August 02, 2009, 01:16:56 AM
What is the general school of thought on sipering and grooving tires? How are they beneficial to the car's performance? Is one better than the other?

From what I understand, grooving is used for forward or side bite while siping is used to prevent harder compound tires from sealing over. Siping, I think, also allows the tires to generate heat more quickly. I've seen lots of grooving, but not really siping. We race asphalt, so maybe siping is more prevalent with dirt track?

I have only seen and siped my tires for dirt, makes the tires genereate heat quicker or indoor races because the temp is 0-20 degrees.  ;-)
