This has to do with it’s more streamlined designed with longitudinally aligned lugs, allowing it to roll better on highways. And although the Grabber X3 is heavier in comparison, it’s still gets to consume less fuel. Rolling resistance, is determined by tire’s weight for the most part. This again has to do with their structure, where BF Goodrich offers better lateral streamlining, and General X3, longitudinal. Though still out of both the BFG KM3 T/A does better on curved aqua tests, where as the Grabber X3 M/T provides better float speeds on straighter paths. Hydroplaningīoth tires have no issues when it comes to hydroplaning resistance, as with wider channels the water gets to evacuate out effortlessly. So with limited number of sipes, the BF Goodrich KM3 lacks overall, whereas on General Grabber X3, at least you get to have some siping on shoulders, which come in to action on corners.Īnd wet cornering is the biggest challenge for mud tires. Most of the water gets channeled out with grooves, and the little bit that’s left is dealt with sipes. Water is not compressible, so in order for a tire to grip, it need to leave out ASAP. That’s because although they offer ample hydroplaning resistance, they are not able to give satisfactory grip. When it comes to wet traction, you can not expect too much out of mud tires. Though the difference is marginal, and it’s safe if you keep these tires under 40 mph (and this goes especially for wet traction). The BF Goodrich KM3 on the other is slightly more vocal, as its less susceptible to understeer as much. Steering response is heavily impacted by the tire’s weight, and here the General Grabber X3 being 10 pounds heavier creates a larger lag between the inputs and the feedback (of the wheels). So if you consider it’s tread again (by scrolling above), you’d note that, it only makes shoulder lugs and the central lugs look like they are divided from these shoulders.Īnd as these sides come in to action when a tire turns, the KM3 provides a much consistent connection with highways. The tire as I explained above does not offer a directionally-streamlined structure, its the opposite. Sideways grip is seen much better on BF Goodrich KM3. It contain two ribs in the middle which are more joined up together, and make 3 longitudinal grooves providing better streamlining with the road.īFG KM3 on the other hand does things the opposite way around. So why is that? Well, because of it’s structure. And that goes for General Grabber X3, as on this tire you get to see shorter stopping distances (a measure of straight grip). Overall, mud tires compromise on this type of grip a lot, though with some tires having better structure are able to still provide better efficacy over the others. Each of these will be discussed in further detail. Three main elements should be considered: traction, steering, and cornering ability. When it comes to analyzing the dry performance of mud-terrain tires, three main dimensions are judged, they include, grip on straight paths, sideways grip, and steering feedback. So, this tire features more tread depth in comparison. Tread depth stands between 18 and 21/32″, where majority of the sizes carry 21/32″. On the other side, Grabber X3 offers 15 to 22″ (rim sizes).Īnd Load ratings of C, D and E only are available, which offers this tire with weight range of 50 to 90 lbs. The tread depth on all KM3 sizes is 18/32″, and these tires do not come with a warranty. The BF Goodrich KM3 is offered in 56 sizes, ranging from 14 to 22 inches in diameter.Įach size has a speed rating of Q and a load rating of C, D, E, or F, with the heaviest size weighing 83 lbs and the lightest size weighing 37 lbs. They are actually made to scoop the ground, and throw back the stuff to create forward momentum.Īnd if you consider how the tire makes wider lateral channels compared to narrower longitudinal grooves, it starts making sense. Though towards the middle there isn’t much going on on these shoulders, as they are seen with minimal tread features (only small notches on consecutive lugs. These shoulder lugs are staggered and extend down to the sidewalls to produce very thick pattern. It has two ribs in the middle, having thick siping slits in between, and outer shoulder ribs, containing two differently shaped “unique” lugs.
