Lots of 'wheelers swear by siping based on personal experience, but Discount Tires offers proof. The company cites tests on ice by the National Safety Council in which siped tires had 64 percent more breakaway traction (starting from still), 28 percent more spinning traction, and 22 percent better braking compared to unsiped tires. Discount also reports a major airline's tests on ramps flooded with Glycol deicer: Siping increased drawbar pull by 25 percent and braking by 33 percent.
