The Goodyear Eagle F1 All Season features carbon fiber reinforced sidewalls for crisp, responsive handling.

We recently had the pleasure of testdriving Goodyear's latest performance tire, the Goodyear Eagle F1 All Season, under various wet and dry conditions at Daytona International Speedway. Goodyear provided several domestic and import models shod in this tire, as well as its direct competitive cross-reference tire, for us to compare on specially prepared courses that were set up by the great folks at the Richard Petty Driving Experience.

The Eagle F1AS uses the latest carbon-fiber technology. Goodyear's Eagle ResponseEdge (the company's first tire to feature carbon fiber) utilized a single carbon-fiber-reinforced sidewall, while the Eagle F1AS has both inner and outer sidewalls reinforced with carbon-fiber materials. The carbon fiber gives crisp response by reducing sidewall flex. The Eagle F1AS also features Tredlock(TM) technology, which is a series of cups and domes built in between the tread blocks. These cups and domes fit together and lock the smaller tread blocks into one larger tread block during cornering to stiffen the tread and keep more rubber on the road.

The Goodyear Eagle F1AS has two different tread zones: the all-season zone and the ultra-high-performance zone. The ultra-high-performance zone consists of aggressive shoulder blocks and a continuous center rib that provides precise handling and steering precision. The all-season zone is the remaining two ribs of tread blocks between the center rib and the shoulder blocks. This zone features Aquachutes(TM) to enhance traction in rain and light-snow conditions. The Eagle F1AS also features a silica tread compound with a DuPont Kevlar layer, directional tread pattern, built-in rim-protector tire edge, and Goodyear's PermaBlack(TM) compound to keep the sidewall looking new throughout the life of the tire.

The Eagle F1AS is available in 22 sizes, from 16- to 18-inch wheel diameters, with more sizes coming soon. They are all backed by the Eagle Performance Package, which includes a 30-day trial period, roadside assistance, online registration, and nationwide warranty service.
