Spaceman Spiff raises the key question that needs to be answered when deciding on a tire. As for brands it kind of becomes a Dodge/Chevy/Ford thing because everyone is going to have their favorites. Once you define what kind of tire you need for your intended usage, you might go to one of the tire dealer websites which often breakdown the differences between tire manufacturer and sometimes reviews. Personally I tended to go with Goodyear, BF Goodrich, Michelin, Cooper & General brands over the years. My truck is now 2-years old with very low mileage and the original tires (Nexen). They have been ok for our use so far, but I am planning to replace them by the end of the year when we will be going fulltime and plan on doing considerably more boondocking. So I will be looking at all terrain style tires to better handle some off pavement roads, snow etc.
