The On-/Off-Road All-Terrain class is one that receives much attention from owners of light trucks and SUVs looking for a more aggressive tire than their Original Equipment. With a few exceptions, most of today's trucks and SUVs come shod with standard Highway All-Season tires that put an emphasis on treadlife and a quiet ride.
What is missing from these O.E. tires? It most cases, it's an aggressive biting edge that's capable of light off-road or heavy snow use, while still maintaining acceptable levels of treadwear and road comfort. Tires in this performance category are not to be confused with Off-Road Maximum Traction tires. In many cases, On-/Off-Road All-Terrain tires are available with mileage warranties from the manufacturer.
A fine example of a do-it-all all-terrain is the Firestone Destination A/T. This tire offers a degree more biting edge over most factory tires without becoming too extreme. While tires exist that might perform better in dedicated off-road situations, few tires are as versatile as this one. The well-rounded nature of this tire has translated in a first place ranking in our Tire Survey Results.
Available for a wide range of applications, shop by vehicle to see if this tire is a match for your light truck or SUV.
A couple of months ago I wrote "Get More for Your Money When Replacing Your Corvette's Run-Flat Tires" that covered fitments for the 1997-2004 C5 models of Corvettes. For those of you interested in the newer C6 model Corvettes (2005-2012), the front tire size is 245/40R18 and the rear size is 285/35R19. Although the original tires on the C6 Corvette are a newer design and generally higher regarded than the C5's tires, there's always room for improvement.
Ultra High Performance All-Season
If you need to drive your C6 Corvette in near-freezing conditions or light snow, take a look at an all-season tire. Two of my favorite run-flat all-season tires are made in the C6's sizes, the Michelin Pilot Sport A/S Plus ZP and Bridgestone Potenza RE960AS Pole Position RFT. Even if you don't need the cold weather capability of all-season tires, they're quieter and have a bit longer treadwear than their summer-only counterparts.
Summer Tires
The top summer performance run-flat tires would be the Michelin Pilot Sport PS2 ZP and Firestone Firehawk Wide Oval RFT. Keep in mind that these tires will lose much of their grip as the temperature nears freezing. They're not designed to be used on snow-covered roads or during icy conditions.
