BFGoodrich All-Terrain T/A KO Tires - Tire Test Guide

The Benchmark All-Terrain Tire

In 1972, a race vehicle equipped with a set of BFGoodrich All-Terrain tires crossed the finish line first at the Baja 1000-this legacy carries on today. The BFGoodrich All-Terrain features the most iconic tread block pattern of any tire, although it may not look the flashiest compared to other tires' artistic patterns. This sought after tire was out of reach for many diesel enthusiasts with big, heavy trucks because of load capacity issues-until now. Recently, BFGoodrich released its E-load-range-rated tires just for us diesel guys. So whether you use your diesel to tow, commute, or win the Baja 1000, these venerable and versatile tires should keep you rolling for many trouble-free miles. Furthermore, all BFGoodrich tires have a limited warranty, which covers defects in workmanship and material for the life of the original usable tread, or for six years from date of purchase, whichever occurs first.

A close-up look at the BFGoodrich All-Terrain reveals sipes, which are small slits in the tread blocks of tires. These sipes provide extra gripping edges and allow the tire to conform to the road. On the BFGoodrich tires we tested, each tread block had two sipes. Another thing we liked about these tires was the shoulder blocks (or lugs) found on the outside edge. These come into play in loose terrain, or when the tires are aired down. The space between the tread block design is called the void, and this space allows for water, snow, and mud displacement. The BFGoodrich All-Terrain KOs are said to feature 40 percent more void on the outside lugs compared to the original BFGoodrich All-Terrains. Some of the benefits you can't see include a high-strength, single-strand bead construction, two full-width steel belts, and three polyester plies in the sidewalls. This, along with the dual-compound tread, provides puncture resistance and great traction.
Steel Wheels
We decided to stick with our factory Ford steel wheels because they are cheap, strong, and easy to replace if damaged. We also considered our dry environment and figured we didn't have to worry about them rusting. Our wheels measure 16x6 inches and feature four cooling slots and an 8-on-6.5-inch bolt pattern. Another good thing about steel wheels is they are easy to paint.
Since most of our driving is done on the mean city streets of Los Angeles, we only briefly considered a mud-terrain tire. For us, going from a mud-terrain tire to an all-terrain wasn't much of a stretch, since our commute involves rough surface streets, and our daily grind is very similar to an off-road race. There are potholes that eat fancy rims on low-profile tires for breakfast, and in order to keep up with traffic, we put distance on tailgating vehicles by blasting through the rough stuff. Still, we know that if our truck ever comes across a big mud pit, we'll lack the willpower to stay out of it. Perhaps then we'll wish we went with the aggressive mud-terrains, but besides that scenario, these All-Terrains seem to be ready for anything.
