The Round Files
Tires-what can we say? They're round, full of air, and, well, we have the cavemen to thank. But nowadays tire technology has graduated with honors from its rocky start to becoming monster meats that can even offer a smooth-handling and silent ride on the street-and with durability built in if there are also daily-driver chores. All-terrain tires have developed a reputation of being able to perform strong in literally all types of terrain-versus that just being a marketing phrase-while some mud tires can be impressively effective at walking over boulders too. Here's a look at the mix of rubber that's out there, including old favorites with new sizes.
