275/70R18 tires

275/70R18 is the 33-inch tire of the factory off-road half-ton. Ram fits it to the 1500 Rebel, Nissan to the Titan PRO-4X, Ford to the F-150 Tremor and Chevrolet to the 2022 and later Silverado ZR2. Choice is thin: the retailer lists only 21 tires in this size. Below are real prices for 13 tires in stock, our in-stock picks, and what to know before you replace a factory off-road tire.

What 275/70R18 tires cost

Prices are per tire, before mounting and balancing. A set of four in the mid range comes to roughly $824 to $1,224, and a brand rebate can take another $50 to $110 off, see this month's deals.

A narrow market for a capable size

Because the size is used almost only by off-road trims, far fewer tire lines are offered in it than in 275/65R18 or 275/60R20, with fewer budget options; our budget pick is one of the lines missing here today. When you find a tire you want, buy all four at once from the same batch; mixing production dates in a size with thin stock is common and avoidable.

The size is about 33.2 inches tall. If you ever need to buy a single tire after a sidewall cut, match the model and get the new one shaved or worn as close as possible to the others, especially on a truck driven in four-wheel drive.

Standard load or load range E

Our two in-stock picks show the split in this size. The General is a standard-load 116S tire at about 45 pounds; the Goodyear is a load range E, 125S tire at about 54 pounds with an 80 psi maximum. Rebel, Tremor, PRO-4X and ZR2 owners who mostly carry people and gear will find the standard-load tire rides better and steers more crisply; the E-rated tire is for trucks that tow heavy trailers or carry campers.

What the numbers on the sidewall mean

A 275/70R18 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.

In this size our picks are marked 116S on the General Grabber A/T X (2,756 lb per tire, rated to 112 mph) and 125S on the Goodyear Wrangler All-Terrain Adventure with Kevlar (3,638 lb per tire, rated to 112 mph). The first number is the load index, the letter the speed rating; a tire with equal or higher values than your placard is fine, a lower one is not.

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.

Ironman All Country A/T. Our usual budget all-terrain; the retailer is not stocking it in 275/70R18 today.

General Grabber A/T X, $284.99. General's all-terrain, with 14/32 inch of tread, the 3PMSF symbol and tread that can be studded where studs are legal. General's feature list gives a 60,000-mile warranty. In this size it is a standard-load 116S, our pick for most off-road half-tons.

Goodyear Wrangler All-Terrain Adventure with Kevlar, $325.02. The heavy-duty option: a Kevlar-reinforced load range E casing rated 125S, with 15/32 inch of tread, the 3PMSF symbol and a 60,000-mile warranty. Right for a truck that tows; firm for one that does not.

What 275/70R18 tires cost across the whole range

Of the 21 tires listed in this size, 13 are in stock today. The lowest price is the Landspider CityTraxx H/T at $147.96, a 125S tire. The median is $261.99; a third of the tires cost $205.96 or less, and the top five percent start above $428.76. 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.

The same tires in neighboring sizes

The General Grabber A/T X, our mid-range pick here at $284.99, is also stocked in 31x10.50R15 ($228.99) and 33x12.50R15 ($263.96). The Goodyear Wrangler All-Terrain Adventure with Kevlar, our premium pick here at $325.02, is also stocked in LT275/70R18 ($292.96), 265/70R17 ($298.99), 285/70R17 ($312.99) and 245/75R16 ($195.96). 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 Ironman All Country A/T, carries the 3PMSF symbol; for that, look at the all-weather and winter tires.

Frequently asked questions

How much do 275/70R18 tires cost?

Expect $148–$206 per tire for a budget brand, $206–$306 for a mid-range tire like the General Grabber A/T X, and $306–$429 for a premium tire like the Goodyear Wrangler All-Terrain Adventure with Kevlar. A set of four therefore starts at about $592. Add roughly $15 to $45 per tire for mounting and balancing.

What vehicles use 275/70R18 tires?

275/70R18 is original equipment on Ram 1500 Rebel (2019-2024), Nissan Titan PRO-4X (2017-2024), Ford F-150 Tremor (2021-2024), Chevrolet Silverado 1500 ZR2 (2022-2024) and GMC Sierra 1500 AT4X (2022-2024), 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 275/70R18 tire?

For most drivers our mid-range pick, the General Grabber A/T X, 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 Ironman All Country A/T is a sound choice.

Can I replace just one or two 275/70R18 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.
