This article suggests a method of coping with winter roads and tire traction. The process is called siping and involves slashing tires, that is, making thin cuts across the tire all the way around. Tire engineers have been impressed with test results which show that on snow and ice, siped tires were better performers in terms of traction, braking, and cornering. Also tread life was increased. Siped tires are not only safer on roads that are icy, snow-packed, or filmed with water, they are also cost-effective even on dry roads. Now, molded sipes, a process done during manufacturing, are an almost standard part of tread designs, but are not as effective as siping, an after purchase process. Presently, tire-slashing machines are manufactured by Saf-Tee Siping and Grooving, Inc., the only manufacturer of after-purchase siping equipment.
