Goodyear introduced a long-lasting Assurance MaxLife tire and an Eagle tire for police vehicles at its annual dealer conference, held in Nashville this year.

The new Assurance MaxLife is the highest-mileage tire Goodyear has ever made and comes with an 85,000-mile warranty, the Akron tire maker said Friday.

The MaxLife uses what Goodyear calls “TredLife Technology” that provides up to 30 percent more miles compared to the standard all-season tire. The tire also features a treadwear gauge that shows drivers how much tread life remains as the tire wears.

The MaxLife will be available in 45 sizes, from 15 inches to 20 inches, meaning it will fit on approximately 75 percent of the cars, minivans and SUVs now on the road today.

The Assurance line of tires was first introduced in 2004. Goodyear said it has since sold more than 60 million Assurance tires.

Goodyear also showed off the Eagle Enforcer All Weather police tire at the conference.

“This tire is for law enforcement agencies that need the enhanced winter traction of a mountain snowflake tire and the reliability and responsiveness of a pursuit tire,” Andy Traicoff, vice president, North America Sales, said in a statement.

Goodyear said the Eagle tire uses a multi-zoned tread compound to improve grip and cornering stability; a soy-based rubber compound with silica for all weather traction; an asymmetric tread design with sweeping tread grooves for better traction, control, and enhanced steering response; and aggressive shoulder blocks and wide lateral grooves.
