All-Terrain All-Season Tire

The Royal Black Terra Force AT is an all-season tire built for light trucks and SUVs. It carries a 275/55R20 size with a 117 load index and T speed rating. The XL load range supports heavy-duty use. This tire is not for buyers who need dedicated winter traction or run-flat capability.

Sustained Load Behaviour

The reinforced internal structure maintains the tire's optimal shape under heavy loads during extended driving. A UTQG treadwear rating of 660 indicates durable compound life over long distances. The staggered block placement with optimized grooves preserves grip on soft and uneven terrain without rapid degradation. It suits drivers who regularly carry heavy cargo.

Interface Practical Limits

The tire fits a 20-inch rim and has an overall diameter of 31.9 inches with a section width of 275 mm. Speed is rated up to 118 mph. The UTQG traction rating of A and temperature rating of A define wet braking and heat resistance limits. Buyers needing a different rim diameter or higher speed rating should look elsewhere.

Questions about this item

How much road noise and heat should I expect from the Royal Black Terra Force AT 275/55R20 when driven all day on highways?

The aggressive all-terrain tread blocks and 9/32-inch tread depth typically produce more road hum and heat than highway tires, especially at sustained speeds near the 118 mph T rating.

What wheel width and rim must I already own to mount this 275/55R20 XL tire?

You need a 20-inch diameter rim with a width approved for 275 mm section width and an XL load-range rating to support the 117 load index.

Will the 31.9-inch overall diameter of this Terra Force AT fit my older SUV without rubbing or speedometer error?

At 31.9 inches tall and 275 mm wide, it is larger than many factory P-metric tires; verify your wheel-well clearance and recalibrate the speedometer for the new rolling circumference.
