Kumho Road Venture MT71 Mud-Terrain Tire
The Kumho Road Venture MT71 uses increased block stiffness in its tread to enhance both on-road and off-road handling characteristics. This creates a more stable and responsive feel behind the wheel, whether you’re on the highway or navigating a technical trail. The high-void tread pattern is central to its off-road capability.
Featuring a zig-zag and dual pitch design, the tread pattern is optimized to provide maximum traction in loose surfaces like mud, sand, and gravel. Additionally, Kumho has integrated mud and stone ejector bars between the shoulder lugs.

The quality of materials and construction is aimed at serious bashers and racers, offering the durability needed to survive repeated high-impact jumps and high-speed runs.
What to Look For in the Best Tires For Big Rock 6s
Choosing the right tires for your Big Rock 6s isn’t just about looks; it’s about matching the tire to your driving style and the surfaces you hit most. I’ve learned that getting this wrong can mean less fun, more breakages, and a lighter wallet. The first thing I always check is the wheel hex size. The Big Rock uses a 14mm hex, so you need to make sure any tire and wheel combo you pick is built for that, or be ready to use adapters, which can add slop.
Next, consider the terrain. Are you mostly on grass and dirt, or do you find yourself on pavement and hardpack? For loose surfaces, a more aggressive, open tread pattern with taller lugs will dig in and give you awesome traction. If you run a lot on harder surfaces, a tighter, less aggressive tread will last longer and give you more predictable handling. The compound matters too. A softer tire compound grips better but wears out faster on asphalt. A harder compound lasts longer but might slide around more on dirt.
Then there’s the question of belted vs. non-belted tires. Standard, non-belted tires are common and work great, but at the high speeds the Big Rock 6s is capable of, they can balloon dramatically. This looks wild but hurts handling and can lead to blowouts. Belted tires have internal reinforcement to resist this ballooning, giving you more stability at top speed and often longer life. They’re usually heavier and can put more strain on your drivetrain, but for speed runs or high-power setups, they’re often worth it.
Finally, think about weight and durability. Big, heavy tires look tough but will affect your truck’s acceleration, braking, and can stress your steering servo and drivetrain components. Lightweight tires are easier on the truck but might not be as tough. I look for a balance – a tire that’s robust enough for my jumps and crashes without being a boat anchor. Reading reviews and seeing what other Big Rock owners run is the best real-world research you can do for finding the 10 best tires for Big Rock 6s.
Frequently Asked Questions
What size tires fit the Arrma Big Rock 6s?
The stock tires on the Big Rock 6s are 2.8″ in diameter and mount on a 14mm hex. You can go a bit bigger or smaller, but staying close to that 2.8″ to 3.0″ range is generally safe. Going much larger can cause major body rub and put excessive strain on your motor and drivetrain. Always double-check the wheel’s hex size compatibility before buying.
Why do my Big Rock tires balloon so much at high speed?
That wild ballooning effect happens because of centrifugal force. At high RPMs, the force wants to pull the tire outward, and without internal restraint, the soft rubber just stretches. It’s very common with non-belted tires on powerful 6s rigs. While it looks cool, it makes the truck unstable and can lead to a tire coming unglued or exploding. Switching to belted tires is the direct solution to this problem.
Are belted tires always better for the Big Rock 6s?
Not always. Belted tires are fantastic for high-speed stability and reducing ballooning, which is why they’re often in the conversation for the 10 best tires for Big Rock 6s. However, they are heavier, which can slightly reduce acceleration and increase wear on drivetrain parts. They can also be more expensive. If you mostly do bashing and don’t mind some ballooning, standard, high-quality tires can be a more playful and cost-effective choice.
Can I use tires from a different brand like Pro-Line on my Big Rock?
Absolutely! One of the best parts of this hobby is mixing and matching parts. Brands like Pro-Line, Duratrax, and JConcepts make excellent tires. The key is ensuring the wheel has the correct 14mm hex fitting. Many aftermarket tires come as “tires only,” meaning you’ll need to buy compatible wheels separately and glue the tires on yourself, which is a standard RC task.
How do I prevent my tires from coming unglued?
Tires coming unglued is a common headache. First, make sure you’re using a proper CA (cyanoacrylate) tire glue. Before gluing, I rough up the inside edge of the tire and the outer edge of the wheel with sandpaper to give the glue something to grip. Apply a solid bead of glue all the way around, and use clamps or tape to hold the tire tightly to the wheel while it cures. Avoiding excessive water and checking for wear after hard runs helps catch a problem before it ruins a tire.
