Goodyear's most recent update to the popular Assurance TripleTred design includes an innovative new tread feature - Evolving Traction Grooves - that helps maintain wet traction, even as the tire wears down. These new grooves are featured in the Assurance TripleTred All-Season and generate more rain, slush and snow traction longer into the tire's life.
As most drivers have experienced, a tire's wet traction tends to diminish as the tread wears down and loses the tread depth needed to pump water out from under the contact patch. It's for this reason that we consider a tire's wet traction capability to be compromised when as little as 4/32" of tread depth is remaining. To see why replacing your tires at this tread depth level may be important to your driving needs, read "Measuring Tire Tread Depth with a Coin." To counteract this issue, the Evolving Traction Grooves begin as 1/10" wide sipes to maximize footprint contact when the tire is new and broaden into wider lateral grooves as the tire wears down. The wider grooves can now channel water out from under the contact patch more quickly - which enhances wet and light snow traction.
When it comes time to purchase your new set of Goodyear Assurance tires, be sure to take a look at our results from "Testing the Goodyear Assurance TripleTred All-Season."
