The engineers at Consumer Reports (CR) outdid themselves in the December issue. They tested 102 tires in seven categories, including all-season truck. And six different tire brands topped their respective segments. Here is an abbreviated look at the tires CR ranked best-of-class..... 1. Performance Winter/Snow. The Vredestein Wintrac Pro finished first, six points ahead of the runner-up Michelin Pilot Alpin PA4. The Wintrac Pro received top marks in three of the nine test categories: hydroplaning resistance, snow traction and ice braking. It received the second highest marks (based on five degrees from better to worst) in dry braking, handling and ride. The Pilot Alpin PA4 was top ranked in hydroplaning resistance and ice braking. Both were the only tires in the category recommended by CR, with the Wintrac Pro priced $10 less than the Alpin PA4. 2. Ultra-High Performance All-Season. The Goodyear Eagle Exhilarate was first, followed by four lines tied for second: Michelin Pilot Sport A/S 3+, General G-Max AS-05, BFGoodrich g-Force Comp-2 A/S and Vredestein Quatrac Pro. The Eagle (handling, hydroplaning resistance) and Pilot Sport (dry braking, hydroplaning resistance) were at the top of the scale in two testing categories each. CR recommended the Michelin, General (by far the lowest-priced of the top 13 tires) and Vredestein tires. 3. Ultra-High Performance Summer. The Michelin Pilot Sport 4s finished with 76 points, two ahead of the Continental ExtremeContact Sport and General G-Max RS. All three were recommended by CR. 4. All-Season. The General brand broke through with its T-rated Altimax RT43. It not only scored three more points than the Michelin Defender T+H, but also didn't have a bad rating in any test category. CR recommended them both. 5. Performance All-Season. Guess which brand was No. 1? The Michelin CrossClimate+ was first, followed by the Continental PureContact LS (second) and V-rated General Altimax RT43 (third). CR recommended the Michelin and Continental tire lines. 6. Winter/Snow. The 10 tires in this segment were bunched closer than any other, with only seven points separating the first-place tires (Cooper Discoverer True North and Hankook Winter I*cept iZ2) and the last place tire. CR recommended the Cooper, Hankook, Continental WinterContact SI, Michelin X-Ice XI3, and Nokian Hakkapeliitta R3. 7. All-Season Truck. Tied for first were the Continental CrossContact LX20 EcoPlus and the Michelin Premier LTX. There was a three-way tie for third among the Firestone Destination LE2, Pirelli Scorpion Verde All-Season Plus and Michelin Defender LTX M/S. CR recommended all five of these tires.
