One of the most realistic, competitive and aggressive tyres on the market just got a lot bigger, scaling up the classic Mud Slingers look with an even more imposing footprint that delivers serious presence and bite.

Frequently Asked Questions

• What size wheels do these Monster Size Mud Slingers fit? — These tyres are specifically engineered for 40 Series narrow wheels with a 3.8-inch inner diameter, including RC4WD BL44, RC4WD BL04N, and Pro-Line 40 Series Cheyenne Narrow Wheel Part No. 2683-01. Due to the specific engineering of RC4WD tyres and wheels working together as a system, we can only guarantee fitment with RC4WD wheels, though in some cases they may work with other manufacturer's 40 Series wheels. RC4WD cannot control other manufacturers' product tolerances, so fitment with competing brands may vary.
• Will these tyres fit my truck? — These Monster Size tyres are designed for large-scale RC trucks including Traxxas Revo, Traxxas T-Maxx, HPI Savage, Tamiya Clod Buster, Tamiya TXT-1 and Tamiya Juggernaut, provided you have compatible 40 Series narrow wheels fitted. If you're unsure about your specific vehicle, we recommend contacting RC Model Shop for expert guidance before purchasing, as you must have appropriate wheels to run these tyres successfully.
• How many tyres do I need to buy? — Each package contains two tyres and two foam inserts, which will cover two wheels on your truck. For a complete set of four tyres (front and rear), you will need to purchase two sets of this product, bringing the total cost to £89.28 at the current price of £44.64 per pack.
• What makes these tyres different from other monster truck tyres? — The Mud Slingers Monster Size represents a scaled-up version of one of the most recognised and respected tyre patterns in RC. RC4WD's advanced X4 medium compound formulation provides excellent balance between grip and durability, whilst the 8mm tread depth and aggressive pattern design offer genuine self-cleaning characteristics and realistic scale proportions that set these tyres apart from standard alternatives.
• Are these suitable for beginners? — Yes, these tyres are suitable for RC enthusiasts of all skill levels, though you do need to already own a compatible large-scale truck and 40 Series wheels. They are straightforward to fit and require no special tools or expertise beyond standard tyre mounting. However, beginners should ensure they have the correct wheel fitment before purchasing.
• What's the difference between the Monster Size and standard Mud Slingers? — The Monster Size represents a scaled-up version of the classic Mud Slingers tread pattern, with a significantly larger outer diameter of 7.55 inches compared to smaller alternatives. This delivers more dramatic visual impact and presence on large-scale builds, making them ideal for collectors and enthusiasts seeking authentic scale proportions.
• Do I need to buy wheels separately? — Yes, these tyres require 40 Series narrow wheels with a 3.8-inch inner diameter. They do not include wheels, so you will need to source compatible wheels such as RC4WD BL44, RC4WD BL04N, or Pro-Line alternatives separately.
• How durable are these tyres? — With 8mm of tread depth and RC4WD's advanced X4 medium compound formulation, these tyres offer excellent durability for both casual bashing and competitive use. The exact lifespan depends on terrain type, driving style and maintenance, but the substantial tread depth provides a long service life before replacement becomes necessary.
