The 315/70R21 is a large tire size commonly found on heavy-duty trucks and full-size SUVs, particularly the Ram 1500 TRX, which uses this size as standard equipment. It is also popular among off-road enthusiasts who lift and modify trucks like the Ford F-150, Chevrolet Silverado, and GMC Sierra to accommodate larger all-terrain or mud-terrain fitments. Due to its aggressive sizing, this tire is especially common on purpose-built overland and trail vehicles.
At the budget end, Atturo and Crosswind offer 315/70R21 all-terrain options at more accessible price points without sacrificing basic off-road capability. Mid-range shoppers should consider Falken Wildpeak or Cooper Discoverer, which deliver strong tread life and off-road performance at a balanced cost. For premium buyers, Nitto Trail Grappler, BF Goodrich KO2, and Toyo Open Country are top choices known for durability, traction, and long mileage warranties.
The best time to purchase 315/70R21 tires is typically during spring and fall sales events, when retailers discount truck and SUV tires ahead of seasonal changeovers. Buying during Black Friday or end-of-year clearance events can also yield meaningful savings on this premium size.
315/70R21 tires typically range from around $200 to over $500 per tire depending on brand and tread type, with all-terrain and mud-terrain variants commanding higher prices due to the specialized construction required for this large, performance-oriented size.
