Being MT, both tires have properties such as wide grooves, aggressive block design with deep biting ability to provide enhanced handling off-road.
The Nitto Trail Grappler provides good traction on mud/snow terrains while KM3 is the best while moving on rocks.
Symmetrical tread design of Grappler provides it directional stability and better traction on road, its deep grooves evacuate the debris and make the tire a good option for driving off road through mud and snow.
BFGoodrich KM3 tread pattern is incredible in managing the gravel effectively, its stone ejector technology tosses off the bombarding rocks, stones and pebbles, while keeping the grooves clean.

Design of These MTs:
Nitto Trail Grappler has a symmetrical tread design of aggressive blocks, off set shoulder lugs and deep grooves.
Central siping of tread blocks wipes off the water very efficiently and make it resistant to hydroplaning.
This tire performs very good while moving on mud or snow due to its deep grooves.
As the snow/mud particles are thrown backwards by the help of grooves, clearing the path of the tire so as a result the traction of tire gets improved.
Although it is good on light snow but it cannot move on deep snow as its grooves aren’t as wide as of KM3.
It also has stone ejectors placed in between the shoulder blocks but as they aren’t bold enough so they are unable to emit big pebbles or stones from getting into the grooves resulting in bad traction on rocky surfaces.
Compare Nitto Trail with other Tires:
BFGoodrich KM3 exhibits a tread pattern of angled blocks with wider grooves in between, edged shoulders and anti-stone groove design.
KM3 is incredible for off roading over the rocky trails due to its open tread design characterizing wider grooves and stone ejectors. It is embarked by a number of rectilinear stone ejectors among shoulder lugs and triangular blocky stone ejectors among central tread ribs.
Grooves with stone ejectors toss the pebbles and stony fragments off the tread and prevent the rocky particles from getting struck into the tire.
These ejectors are effective in preventing the rocks drilling punctures into tread rubber.
The tread blocks of central ribs are marked by sipes, these angled slits wipe off water and fluids quickly and provide grip on wet surfaces.
But the number of sipes is much less as they are only present on blocks of central ribs.
Shoulder lugs are enlarged and edged with large grooves and stone ejectors among them resulting in good traction while cornering and steering through off road surfaces as wide grooves evacuate mud and slush. High void ratio optimizes self-cleaning capacity as dirt, clay and mud is removed out quickly.
On Road Traction is Compromised:
Closely placed tread blocks provide more contact patch enabling Trail Grappler to perform well while moving on road.
As more surface of the tire is in contact with the road so it improves the grip resulting in good overall traction.
High void ratio and open groove pattern of tread play against KM3 on paved surfaces.
It has very less surface area in contact with the road as grooves are wide, this characteristic decreases it’s on road traction.
Trail Grappler performs much better than BFG KM3 in terms of on road traction.
They Have great off road Traction:
Nitto Trail Grappler is a great mud tire because it has deep grooves.
Its tread depth range is 18.9-21 in 32″, the deep tread provides excellent off-road traction as the vehicle cuts through rough surfaces due to its effective evacuation capacity.
This tire has amazing traction on muddy or snowy grounds because its deep grooves throw the snow/mud backwards as the tire accelerates, enabling the vehicle to move forward but still as its grooves aren’t as wide as KM3 so it is unable to perform well in deep snow.
In terms of dealing with gravel Trail Grappler is not as good as its competitor because it has fewer stone ejectors so the pebbles/stones can get stuck into the grooves.
KM3 is excellent for rugged off roading ventures both over the rocky trails and in the muddy bogs because it has wide grooves with superior stone ejectors.
BFGoodrich KM3 possess wonderful self-cleaning properties due to its high void ratio.
It treads depth is within range of 18 in32’’.
Grooves among the blocks provide space to mud, dirt, slush and gravel to escape as the tire moves over rough surfaces, making it highly suitable for tough off-road adventures.
The wide grooves capture the mud/snow particles and throw them backwards as the tire accelerates, enabling the tire to maintain good traction.
These tires perform better on rocky surfaces due to its anti-stone technology as compared with its competitors, it has stone ejectors which emit the stone/pebbles from getting stuck into the tread.
Strengthened notched shoulders exhibit deep biting lugs with edges to enhance off road traction.
This character provides a remarkable handling as edged blocks and wide grooves offer space for the evacuation of mud, clay and gravel.
They are very noisy on road:
Trail Grappler is much quieter as compared to KM3 because its tread blocks are symmetrically designed and are relatively closer.
Aligned Block arrangement over the tread offers a mechanical flow to wind and the tire produces much less noise.
BFGoodrich KM3 produces much noise as most of MT tires due to its wide channels among tread pattern.
As more air particles are trapped in its wide grooves so they collide with the walls back and forth creating more noise.
This resonating effect of sound increases gradually as the tire wears with time.
These tires are Durable:
The 3-ply sidewall and thick rubber construction provide puncture resistance to Trail Grappler.
Thick side walls sustain through harsh off-road conditions.
Symmetrical tread faces less rolling friction and thus prove to be long lasting.
Composition, thickness and pattern of tread makes Nitto Trail Grappler more durable than its competitors.
The average tread wear of KM3 is estimated 60,000 to 80,000 miles.
Stone ejectors and increased width of grooves protect the tread from stony hazards of off-road environment.
Ejectors prevent clogging of grooves with stones which may puncture the tire after sometime.
This unique tread pattern with thicker 3 ply sidewalls, chip and tear resistivity and pinch shock resistance make KM3 a dependable mud terrain tire.
- Trail Grappler is a good off-road tire and provides satisfactory on road experience as well. Its deep tread design performs well through mud and slush as they evacuate from its deep and wide grooves.
- BFGoodrich KM3 is the conqueror of rocks due to its supreme stone ejector tread design. Its wider grooves perform efficiently in evacuating out mud, snow and gravels.
- Trail Grappler has a symmetrical tread pattern which gives it good on-road traction and directional stability. Its closely located lugs make it a quiet tire as compared to most mud terrain tires.
