Just bought an F-150 4X4 with a new set of Ironman All Country ATs. They seem to ride and handle as well as a set of Michelins, at about half the price. Thinking about buying a set of Radial APs for my 4X2. Almost all the reviews look great, but one review stated that a tread separation occurred at 15K. Has anyone here had experience with Ironman tires? That one review out of many gives me some second thoughts. Thanks in advance.
