the first four wheel drive at Pikes Peak, check the tire treatment, this is the only time I've seen lateral cuts in tread

I posted about the Four Wheel Drive company before, as they invented the 4x4 and got the contract from the US Army with the famous Nancy Hank

  1. Cutting grooves in a tyre is called siping and the cuts can go in any direction to aid traction. It can give more grip to tyres that have gone hard.
