TerrainContact A/T LT275/55R20/10 120/117S
The Continental TerrainContact A/T LT275/55R20/10 120/117S (SKU 15578700000) is the heavy-duty workhorse of the 275/55R20 size family. The '/10' designation confirms true ten-ply construction, and the dual 120/117S load rating serves both SRW and DRW configurations at maximum gross vehicle weight. Designed for trucks that tow heavy trailers or operate at their weight rating consistently, this tire brings the same all-terrain tread performance to commercial and fleet applications that the standard version delivers for consumers.
Key Features & Performance
The thick, reinforced carcass maintains shape under elevated inflation pressures and resists the bead unseating that can occur when extreme off-road airing down meets an abrupt rebound load. The all-terrain tread channels maintain grip in mud and gravel, and the heat-resistant compound copes with the thermal demands of extended towing in mountain passes.
Vehicle Compatibility
Vehicle Compatibility: The LT275/55R20 is used on Ford F-250/F-350 Super Duty (2017–2022 with 20-inch rims), Ram 2500 (2019–2022), Chevrolet Silverado 2500HD (2019–2022), and GMC Sierra 2500HD (2019–2022 SLT/Denali). Match load range to your truck's GVWR as specified on the door jamb sticker.
Why Choose This Tire?
The TerrainContact A/T LT275/55R20/10 carries a mileage warranty and stands as Continental's most durable 20-inch solution for demanding commercial towing applications.

Do you have a question about TerrainContact A/T LT275/55R20/10 120/117S?
Yes, if you want an all terrain that behaves like a road tire most of the time. The TerrainContact A/T emphasizes a quiet ride, stable highway handling, and strong wet braking, then adds dependable traction for gravel and light mud. It is a smart choice for daily drivers who occasionally head off pavement. For extreme routes or deep mud, a more aggressive A/T or mud terrain will add bite, but you will trade some on road comfort and noise.
TerrainContact A/T is designed for year round use, with dense siping that helps in cold and wet conditions. Many all terrain tires carry the M+S marking, and some sizes in various product lines may also carry the 3PMSF severe snow symbol. Markings can vary by size and spec, so check the sidewall of the exact tire you plan to buy if severe snow certification matters in your area. For frequent ice and deep snow, a dedicated winter tire remains the safest choice.
Popular sizes include 245/60R18, 255/65R17, 265/60R18, 265/70R17, 265/75R16, 275/55R20, 275/65R18, and 275/70R18. Fitment depends on your original equipment size, load index, and speed rating, so check the driver door jamb label or owner manual, especially if you tow. If you are upsizing, confirm clearance at full steering lock and full suspension compression. A professional installer can recommend ideal sizes, recalibrate TPMS if needed, and perform a road force balance for a smooth ride.
Longevity depends on driving style, rotation intervals, inflation, alignment, and road conditions. With proper care, including rotations every 5,000 to 7,500 miles, correct air pressure, and periodic alignments, drivers typically see strong tread life for a road biased all terrain. The TerrainContact A/T is covered by Continental limited warranty and treadwear coverage on eligible sizes, with terms that vary. Review the warranty booklet for mileage limits and requirements, and keep service records to preserve coverage and maximize total miles.
For an all terrain, the TerrainContact A/T is engineered to be notably quiet thanks to tuned tread block sequencing and a road focused pattern. Any A/T can get louder as it wears or if rotations are delayed. Vibration usually points to balance, alignment, or a damaged wheel or tire. Ask your installer for a road force balance and proper lug torque, then keep rotations on schedule and pressures set to maintain a smooth, quiet ride.
A/T stands for all terrain. It identifies a tire built to handle a mix of on road driving and unpaved surfaces such as gravel, dirt, or light mud. Compared with highway tires, A/T designs use more open tread blocks, extra biting edges, and more robust construction for durability. They add versatility without the noise and rolling resistance of dedicated mud terrain options.
