LT275/70R18 tires

LT275/70R18 is the standard 18-inch tire on three-quarter- and one-ton pickups: the 2017-on Ford F-250 and F-350 single-rear-wheel in XLT and Lariat trim, the Ram 2500 and 3500 Big Horn and Laramie, and the 2020-on Chevrolet Silverado and GMC Sierra 2500HD. Below are real prices for 282 tires in stock, three picks with the specifications behind them, and why a heavy-duty truck should not be fitted with a tread pattern chosen for looks.

What LT275/70R18 tires cost

Prices are per tire, before mounting and balancing. A set of four in the mid range comes to roughly $804 to $1,116, and a brand rebate can take another $50 to $110 off, see this month's deals.

Load range E is not optional on these trucks

A diesel F-250 or Ram 2500 is heavy before it carries any payload or tongue weight, and the placard calls for a load range E tire, a 10-ply-rated casing, and in this size that means a dual load index of 125/122: 125 when the tire is fitted singly, 122 on a dual rear axle. All three of our picks are marked 125/122, so the choice between them is about tread and speed rating, not strength. A load range C or D tire in the same size will fit the wheel but does not meet the placard on these trucks.

Keep an eye on the speed symbol as well. Two of our picks are Q-rated (99 mph) and the Goodyear is S-rated (112 mph). For a truck that tows at highway speeds in summer heat, the higher rating is the more comfortable margin.

Mud-terrain on a work truck: think twice

Our mid-range pick in this size is a mud-terrain, the General Grabber X3. It is a capable tire on a ranch or a construction site, but on a truck that spends most of its time on the highway it is louder, wears faster and stops a little longer on wet pavement than an all-terrain. The retailer lists no mileage warranty for it. If your truck tows on the interstate, an all-terrain like the Goodyear, or a highway tread, will cost less per mile and ride more quietly.

Replace tires in sets of four on these trucks, and check the date code when they arrive: a heavy-duty tire that has sat in a warehouse for years is past its best regardless of tread depth.

What the numbers on the sidewall mean

A LT275/70R18 tire is 275 millimeters wide, its sidewall is 70 percent of that (about 7.6 inches tall), and it mounts on a 18-inch wheel. That works out to an overall diameter of roughly 33.2 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, $209.96. A rugged-terrain tire, between an all-terrain and a mud-terrain, with a 45,000-mile tread life warranty and a 460 treadwear grade in a representative size. It is load range E and marked here, so it meets the heavy-duty placard; the Q speed rating is the trade-off for the low price.

General Grabber X3, $366.99. General's mud-terrain, with deep, self-cleaning tread and the company's Duragen casing technology. It is load range E and marked, but the retailer lists no mileage warranty, and on pavement it is the noisiest of the three. Buy it for a truck that works off-road, not for highway towing.

Goodyear Wrangler All-Terrain Adventure with Kevlar, $292.96. An all-terrain reinforced with DuPont Kevlar, with the three-peak mountain snowflake symbol and a 60,000-mile tread life warranty. In this size it is a load range E tire, the only S-rated pick here, and the best all-round answer for a heavy-duty truck that tows.

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.

None of our picks in this size, the Atturo Trail Blade X/T, carries the 3PMSF symbol; for that, look at the all-weather and winter tires.

Frequently asked questions

How much do LT275/70R18 tires cost?

Expect $144–$201 per tire for a budget brand, $201–$279 for a mid-range tire like the General Grabber X3, and $279–$375 for a premium tire like the Goodyear Wrangler All-Terrain Adventure with Kevlar. A set of four therefore starts at about $576. Add roughly $15 to $45 per tire for mounting and balancing.

What vehicles use LT275/70R18 tires?

LT275/70R18 is original equipment on Ford F-250 (2017-2024, XLT/Lariat), Ford F-350 SRW (2017-2024), Ram 2500 (2010-2024, Tradesman/Big Horn), Ram 3500 SRW (2010-2024), Chevrolet Silverado 2500HD (2020-2024, WT/LT) and GMC Sierra 2500HD (2020-2024, SLE), 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 LT275/70R18 tire?

For most drivers our mid-range pick, the General Grabber X3, 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 Goodyear Wrangler All-Terrain Adventure with Kevlar 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 LT275/70R18 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.
