Shop 275/70R18 Tires

Yes. The large diameter (33.2″), wide footprint (275 mm), and tall sidewall (7.6″) provide strong load stability and traction. Many tires in this size are available in higher load ratings such as XL and LT load ranges, making them suitable for towing trailers, hauling payloads, and heavy-duty truck use. The taller sidewall also helps absorb load stress, improving durability under heavy-weight conditions.

The 275/70R18 listings reviewed on NeoTires range from about $276.76 to $361.97 per tire (at research time). Price differences mainly track brand, mileage warranty, and service description (116S, 116T, or 125/122S), so hold your required service description fixed before comparing prices across the 275/70R18 grid.

A 275/70R18 tire has a calculated overall diameter of 33.2 inches, placing it in the 33-inch tire class commonly used on full-size trucks and off-road SUVs. This diameter provides greater ground clearance than smaller factory sizes, such as 265/65R18 (31.6″). The taller height improves approach angle and off-road capability while fitting many stock suspension setups, though a leveling kit may be required on some configurations to avoid rubbing at full steering lock.

A 275/70R18 tire has a calculated overall diameter of about 33.2 inches, so it's commonly called a "33-inch tire" in truck-tire shorthand even though the precise figure is closer to 33.16 inches. This rounding is standard across the tire industry and doesn't affect fitment. When comparing 275/70R18 to true 33x12.50 sizes, note the section width also differs (10.8" vs. 12.5").

Among the 275/70R18 all-terrain listings reviewed on NeoTires, the Falken Wildpeak A/T4W currently shows the most displayed reviews, followed by the Nitto Terra Grappler G3 and the General Grabber A/TX. Reviews do not reflect an independent performance test but rather customer satisfaction with the products used. 

The approved rim width range for 275/70R18 tires is 7.0 to 9.0 inches, with 8.0 to 8.5 inches considered ideal. This range is defined by TRA and confirmed by manufacturer spec tables from Michelin, Goodyear, and Falken. Narrower rims improve sidewall protection and off-road durability, while wider rims improve steering response and handling stability. Most OEM truck wheels in this size range fall between 7.5″ and 8.5″, which provides optimal tire shape and load support.

Most half-ton F-150 and Silverado 1500 trucks ship from the factory with a smaller-diameter tire, so 275/70R18 is typically installed as a plus-size aftermarket upgrade rather than a direct factory match. Fitment without rubbing depends on trim, wheel offset, and whether the truck has a leveling kit, so confirm your exact vehicle's factory size using the VIN lookup guide above before ordering.
