Tested: Street vs. Trail vs. Mud Tires

Let’s face it, the taller and more aggressive a tire isthe more truck guys like it. The appeal of an extreme-traction mud tire just suits the image and idealized purpose of a pickup. Even though we all tend to drive our diesels on the streetmore than on the dirtwe all seem to prefer the looks of an aggressive tire.   |   tested Street Vs Trail Vs Mud Tires test Tires While fashion trends suggest mud tires are better than all-terrains, the irony is that you can only see a tire’s looks when the wheels are stationaryand who cares how good a tire is when it’s not doing anything? One could argue that the function of a tire is most important when it’s moving, so we decided to put the good-looking aggressive tires (that we all dream about) up against the more humble appearing ones (that we should all probably be running). We also added in a new, middle-ground tire from Nitto that might split the difference between the two extremes.

Terra Grapplers vs. Trail Grapplers vs. Mud Grapplers


We selected three different Nitto tires and tested them on the same truck with the same air pressure (50 psi) and same style rims. The terrain for the examination included loose sand, hard-packed dirt, rocks, steep hills, and mud. We also tried them on the street in order to give you a real-world case study to help you make your next tire-buying decision. Working with Discount Tire’s Abel Arreol, who manages the company’s America’s Tire store in Glendale, California (818 507-6049), we had all 12 Nitto tires mounted on 12 identical American Outlaw Colt 20x9-inch aluminum wheels. We then tested each tire on an ’05 Dodge Ram 2500 to see how they all worked.
