LT275/65R20 tires

LT275/65R20 is the 20-inch size of the premium heavy-duty pickup. Ford fitted it to the F-250 King Ranch from 2011 to 2016 and to the F-250 Lariat and Platinum from 2017, and Chevrolet and GMC use it on the 2020 and later Silverado and Sierra 2500HD in their upper trims. Below are real prices for 225 tires in stock, three load range E picks, and how to set pressures when you tow.

What LT275/65R20 tires cost

Prices are per tire, before mounting and balancing. A set of four in the mid range comes to roughly $828 to $1,324, and a brand rebate can take another $50 to $110 off, see this month's deals.

All three picks are load range E

In this size every pick is a ten-ply-rated, load range E tire with an 80 psi maximum and a 126/123 rating: 3,748 pounds per tire used singly. That is what these trucks need, since a three-quarter-ton with a diesel engine puts a lot of weight on the front axle even before it is loaded. Do not fit a lighter P-metric or load range C tire in the same dimensions, even if a shop has one in stock.

The differences between the picks are speed rating and tread. The Atturo is Q-rated, 99 mph, while the Nexen and BFGoodrich are S-rated, 112 mph; for a truck that tows at highway speed, the S rating is the safer margin.

Setting pressure for the load, not the sidewall

The 80 psi on the sidewall is the maximum, not the target. A heavy-duty truck running empty at 80 psi rides hard and wears the center of the tread. With a fifth-wheel or gooseneck trailer, the rear tires may need close to the maximum. The reliable way is to weigh the truck at a scale, loaded as you will drive it, and look up each axle's weight in the tire maker's load and inflation table. Write the two pressures on a card in the glove box, one for empty and one for towing.

What the numbers on the sidewall mean

A LT275/65R20 tire is 275 millimeters wide, its sidewall is 65 percent of that (about 7.0 inches tall), and it mounts on a 20-inch wheel. That works out to an overall diameter of roughly 34.1 inches. Every replacement has to match all three numbers, and the load index and speed rating on the placard inside the driver's door have to be met or exceeded. The LT prefix marks a light-truck tire built for heavier loads and higher pressures; the load range letter on the sidewall (C, D or E) should match what the placard calls for.

Our guide on reading a tire size walks through the markings, and this one lists every load index and speed code.

Our three picks, side by side

One tire at each price level from what the retailer stocks in this size, with the mileage warranty and UTQG grades as published by the manufacturers and their retailers. Treadwear is the number to compare: it is a relative wear rate, so 700 should last roughly twice as long as 350 on the same car.

Atturo Trail Blade X/T, $225.96. Atturo's hybrid tread with a rim guard and deep 17.5/32 inch tread, in a load range E casing rated 126/123Q. It is warranted for 45,000 miles and graded 540 A B in this size. The Q speed rating, 99 mph, is the lowest of the three.

Nexen Roadian ATX, $311.96. Nexen's all-terrain with a dual sidewall design, here load range E and S-rated, with 16/32 inch of tread, a 60,000-mile warranty for LT sizes and the 3PMSF symbol. Strong value for a heavy-duty truck.

BFGoodrich All-Terrain T/A KO3, $440.96. BFGoodrich's current all-terrain in a load range E, 126/123S construction, with 15/32 inch of tread, the 3PMSF symbol and a 50,000-mile warranty. Slightly lighter than the Nexen at 63.5 pounds.

What LT275/65R20 tires cost across the whole range

Of the 287 tires listed in this size, 225 are in stock today. The median is $248.96; a third of the tires cost $206.96 or less, and the top five percent start above $457. Those are per-tire prices before mounting and balancing, which adds $15 to $45 per tire at most shops, read from the retailer's feed Nov 13, 2026.

Useful if your vehicle came with a different wheel package, or if you are comparing an upsize: the same tire usually costs more per inch of wheel, not per inch of rubber.

Winter on a pickup in this size

Four-wheel-drive pickups satisfy Colorado's Passenger Vehicle Traction Law on the 126 miles of I-70 between Dotsero and Morrison, in force from September 1 to May 31, on the vehicle alone, provided the tires have at least 3/16 inch of tread. A two-wheel-drive truck, still common in work trims, must be on tires marked M+S, 3PMSF or rated all-weather by the manufacturer. Fines start at $130. Nearly every all-terrain tire carries the M+S marking, and the better ones now also carry the 3PMSF symbol, which requires a tested level of snow traction rather than just a tread pattern. An unloaded pickup is light over its rear axle, so on snow the rear tires lose grip first; a few hundred pounds of ballast in the bed over the axle does as much as the tire choice.

Of our picks in this size, the Nexen Roadian ATX and BFGoodrich All-Terrain T/A KO3 carry the 3PMSF symbol; the Atturo Trail Blade X/T does not.

Frequently asked questions

How much do LT275/65R20 tires cost?

Expect $157–$207 per tire for a budget brand, $207–$331 for a mid-range tire like the Nexen Roadian ATX, and $331–$457 for a premium tire like the BFGoodrich All-Terrain T/A KO3. A set of four therefore starts at about $628. 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) 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.
