The tread of a tire refers to the pattern on the outside of the tire that makes contact with the road. The familiar grooves on the tread allow water to move under the tires, which prevents hydroplaning. Tire tread also improves the vehicle’s ability to maintain traction on the road surface. Tires that have had their tread worn down are sometimes referred to as “bare”, and should be retreaded or replaced.
