About the LT275/65R20 size
The premium-trim HD truck size, load range E (3,750 lb per tire). Every A/T and highway line; the Tremor/Power Wagon upsize is 35 in.
The numbers mean: 275 mm section width, sidewall height 65 % of that width, and a 20-inch rim. Overall diameter works out to about 34.1 inches. Any replacement has to match all three, and the load index and speed rating on your door sticker must be met or exceeded. Our guide on reading a tire size walks through it.

Frequently asked questions
How much do LT275/65R20 tires cost?
Expect $139–$206 per tire for a budget brand, $206–$312 for a mid-range tire like the Nexen Roadian ATX, and $312–$453 for a premium tire like the BFGoodrich All-Terrain T/A KO3. A set of four therefore starts at about $556. Add roughly $15 to $45 per tire for mounting and balancing.
What vehicles use LT275/65R20 tires?
LT275/65R20 is original equipment on Ford F-250 (2017-2024, Lariat/Platinum 20 in), Ford F-350 SRW (2017-2024, 20 in), Chevrolet Silverado 2500HD (2020-2024, LTZ/High Country/AT4 20 in), GMC Sierra 2500HD (2020-2024, Denali/AT4 20 in), Ram 2500 (2019-2024, Laramie/Limited 20 in) and Ford F-250 (2011-2016, King Ranch 20 in), among others. Always confirm with the sticker inside your driver's door, because trim levels and wheel packages can change the size.
What is the best LT275/65R20 tire?
For most drivers our mid-range pick, the Nexen Roadian ATX, is the sweet spot of price and tread life. If you keep the vehicle a long time or drive in heavy rain and snow, the BFGoodrich All-Terrain T/A KO3 is worth the extra. On a tight budget the Atturo Trail Blade X/T is a sound choice.
Can I replace just one or two LT275/65R20 tires?
On a front- or rear-wheel-drive car, yes: replace in pairs on the same axle and put the newer pair on the rear. On all-wheel-drive vehicles most makers want all four replaced together, or a new tire shaved to match, because a difference in circumference strains the drivetrain.
