Cosmo has built its reputation for offering a nice blend of quality, aesthetics, and budget-friendly pricing, making it a great option for drivers wanting a stylish yet rugged tire. Conversely, Rolling Big Power (RBP) focuses heavily on the custom truck segment, engineering robust and heavy-duty tires that complement lifted pickups, Jeeps, and extreme 4x4 setups.
Both budget brands have capable off-road tires under their belt. The Mud Kicker from Cosmo and the Repulsor M/T 3 from RBP are the newest additions in their respective manufacturer’s portfolio. While the Cosmo tire is more focused on returning better value with adequate grip and traction, the RBP tire appeals more to drivers wanting mud-terrain tires with heavy-duty construction.
The Cosmo Mud Kicker stands out for its high-value, versatile trail performance. It delivers enhanced grip and traction in deep snow and mud thanks to its aggressive tread pattern and dual-sidewall design. Contrarily, the RBP Repulsor M/T 3 is designed to handle severe off-road environments. It uses massive, alternating tread blocks and an open shoulder design to scoop through loose soil and thick muck. Both are backed by multi-ply sidewall construction for improved internal strength and increased load capacity.

Mud-terrain tires need strong traction as you frequently navigate through loose dirt, sand, rocky trails, and mud. Strong traction helps to maintain the forward momentum and retain control when conditions turn demanding. Let’s see which one performs better in the traction race.
The Cosmo Mud Kicker earns a great traction score of 8.0. It has been designed as the first “Mud Rated” tire in the industry, and features shoulder claws, alternating open scalloped lugs, and deep tread blocks to maximize grip on loose surfaces. The Cosmo mud-terrain tire comes with a reinforced bead area that improves traction when you drive through deep mud and snow, while the tread block divots and stone ejector ridges eliminate debris from the tread, thereby maintaining road contact.
The RBP Repulsor M/T 3 offers a similar traction score of 8.0 and promises solid off-road performance. The RBP tire features large staggered tread elements and an open shoulder design that helps you improve grip on soft surfaces. Additionally, the wide grooves and aggressive tread pattern create numerous biting edges that dig into mud, dirt, and loose terrain. Off-road grip is further improved by the upper sidewall design when the tire tackles ruts and obstacles.

Longevity is one of the vital parameters for you to assess a mud-terrain tire. As aggressive tread patterns can sometimes wear faster, you need a tire with strong durability for long-term value. The Cosmo and RBP mud-terrain tires offer great value, but one tire returns an exceptional tread life. Let’s find out which is that tire.
Securing an incredible score of 9.5 out of 10, the Cosmo Mud Kicker demonstrates its phenomenal ability to provide superior wearability with extended tread life. Thanks to the stone ejector ridges that safeguard it from trapped debris and push them out in a timely manner for increased protection against stone drilling. Lastly, the tire comes with an exceptional 50,000 mile warranty to ensure peace of mind.
Contrarily, the longevity score of 8.3 is decent for the RBP Repulsor M/T 3. Its advanced rubber compound and durable 3-ply sidewall construction help resist damage when it's driven in extreme off-road conditions. While the tire is built for durability, it doesn’t offer the same level of tread life quality as the Cosmo tire.
The Cosmo Mud Kicker emerges as the winner in terms of longevity, which is evident from its higher SimpleScore.
ADVANTAGE: Cosmo Mud Kicker
Mud-terrain tires are suitable for drivers who frequently navigate through mud, dirt, loose gravel, rocks, and other off-road surfaces. These tires offer aggressive traction and higher off-road capability compared to all-terrain tires.
The Cosmo Mud Kicker would be a better choice if you’re looking for a tire capable of handling muddy trails and uneven terrain frequently. The RBP Repulsor M/T 3 is a more suitable option for drivers looking for heavy-duty construction and a confident performer on challenging trails. Serious trail enthusiasts may go for this tire for their lifted trucks, considering the staggered tread blocks and rugged sidewall design.

To sum it up, when you choose between these two mud-terrain tires, consider what matters to you the most. Although the tires perform equally well in terms of traction and handling, the Cosmo Mud Kicker outperforms the RBP Repulsor M/T 3 in service life. However, the heavier-duty construction of the RBP tire makes it a more suitable option in demanding off-road applications.
Considering the 33x12.50R20LT 119Q F tire size, the cost of each Cosmo Mud Kicker tire is around $202 per tire, which means four such tires would cost you around $808. On the other hand, each RBP Repulsor M/T 3 costs about $206 per tire, which brings the cost of four such tires to approximately $824 (a difference of $16).
