RC crawler enthusiasts, get ready to upgrade your ride with these awesome 2.2 inch mud terrain tires! This 4-pack comes complete with foam inserts already installed, so you can get right to mounting them on your rig. Made from high-quality rubber material, these tires feature aggressive lug patterns and narrow design that's perfect for extreme scale all-terrain crawling. The outer diameter measures 130mm (about 5.12 inches) with a width of 54mm (about 2.13 inches) - ideal proportions for serious crawling performance. The uneven surface texture and knurled tread pattern provide incredible grip and road-holding ability on the toughest terrain. Whether you're tackling rocks, mud, sand, or steep hills, these tires deliver unmatched side-hilling performance and forward/reverse traction. The built-in foam inserts give you strong cushioning performance and help maintain tire shape under load, while the high wear-resistant rubber ensures these tires will last through many crawling sessions. They're compatible with most 1/10 scale crawlers including popular models like Axial SCX10, 90047, D90, D110, Tamiya CC01, TRX4, Gen8, and more. The precise craftsmanship makes installation straightforward, and the fine simulation details make your RC car look incredibly realistic. At 544 grams for all four tires, they've got substantial weight for good ground contact without being too heavy. If you're looking to improve your crawler's performance on challenging courses, these tires are an excellent upgrade that won't break the bank!
