33x12.50R20 tires

33x12.50R20 is the best-selling flotation size in the country: the default 20-inch upsize on a leveled F-150, Ram 1500, Silverado, Sierra or Tundra, the common choice on Jeep Wrangler JL and Gladiator owners who moved to 20-inch wheels, and a no-lift upsize on the F-250. It is an LT size in load range E or F, built for trucks that are asked to look the part and work. Below are real prices for 225 tires in stock, three picks with the specifications behind them, and what changes when you leave the factory size.

What 33x12.50R20 tires cost

Prices are per tire, before mounting and balancing. A set of four in the mid range comes to roughly $908 to $1,084, and a brand rebate can take another $50 to $110 off, see this month's deals.

What a 33 does to a half-ton truck

Nobody's truck came from the factory on 33x12.50R20; it is a replacement for a 275/55R20 or 275/60R20, and the change is about an inch to two inches of diameter and an inch or more of width. Visually that fills the wheel wells, which is the point. Mechanically it raises the gearing, so the truck accelerates a little slower and the speedometer reads about three to six percent under the true speed, it adds ten to fifteen pounds per corner of unsprung weight, and the wider tread usually needs a leveling kit of about two inches, and sometimes trimming, to clear the front bumper and liner at full lock. Fuel economy drops by one or two miles per gallon on most trucks.

Because these are LT tires, run the pressure for the load, not the maximum on the sidewall. A load range E tire inflated to 80 psi on an unloaded half-ton rides like a wheelbarrow and wears the center of the tread; most owners settle between 40 and 50 psi on the street and raise it when towing.

All-terrain, rugged-terrain or mud-terrain in a 33

The size is sold in all three. A modern all-terrain with the three-peak mountain snowflake symbol is the right answer for the truck that is daily-driven and occasionally used hard, and it is what most of the stock in this size is. Rugged-terrain or hybrid tires split the difference with larger shoulder lugs and more noise, and look the most aggressive for the least penalty. Mud-terrains are for trucks that see mud and rock, and at 70 pounds or more per tire in this size they are loud and wear fast on pavement.

One practical point: a 33-inch tire will not fit the factory spare carrier under most half-ton beds, so either carry the old spare, accept a mismatched spare for emergencies, or find somewhere else to mount the fifth tire before you need it.

What the numbers on the sidewall mean

33x12.50R20 is a flotation size, the format used on larger truck tires: the first number is the overall diameter in inches (nominally 33 inches, a little less once mounted and loaded), the second is the section width in inches (12.50) and the last is the wheel diameter, 20 inches. These are LT tires with a load range letter on the sidewall, usually E or F here; a replacement should carry the same letter, because the letter sets the maximum inflation pressure the tire is built for.

In this size our picks are marked 114Q on the Atturo Trail Blade X/T (2,601 lb per tire, rated to 99 mph), 119S on the Falken Wildpeak A/T4W (2,998 lb per tire, rated to 112 mph) and 114S on the BFGoodrich All-Terrain T/A KO3 (2,601 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.

Atturo Trail Blade X/T, $198.96. Our budget pick: the lowest-priced tire in this size with a specification sheet we could actually check. A rugged-terrain tire with a 45,000-mile tread life warranty. The published UTQG grade is 460 A B in a representative size: a treadwear number of 460 is typical for this type of tire. It does not carry the 3PMSF symbol; in the snow belt treat it as a three-season tire or look at the all-weather options. A set of four comes to $795.84 before mounting.

Falken Wildpeak A/T4W, $481. The mid-range pick, and the default for most drivers of the vehicles listed on this page. An all-terrain tire with a 60,000-mile tread life warranty (65,000 mi P-metric; 60,000 mi LT sizes). The published UTQG grade is 660 B B in a representative size: a treadwear number of 660 puts it among the longest-wearing tires in this size. It carries the three-peak mountain snowflake (3PMSF) symbol, so it meets the severe-snow traction standard and satisfies the traction laws on its own. A set of four comes to $1,924 before mounting.

BFGoodrich All-Terrain T/A KO3, $484.99. The premium pick, for the owner who keeps the vehicle a long time and drives it a lot. An all-terrain tire with a 50,000-mile tread life warranty. The manufacturer does not publish a UTQG grade for this model in LT sizes, so compare on warranty and tread depth instead. It carries the three-peak mountain snowflake (3PMSF) symbol, so it meets the severe-snow traction standard and satisfies the traction laws on its own. Extras: 10-ply construction in LT sizes. A set of four comes to $1,939.96 before mounting.

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 Falken Wildpeak A/T4W 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 33x12.50R20 tires cost?

Expect $196–$227 per tire for a budget brand, $227–$271 for a mid-range tire like the Falken Wildpeak A/T4W, and $271–$489 for a premium tire like the BFGoodrich All-Terrain T/A KO3. A set of four therefore starts at about $783. Add roughly $15 to $45 per tire for mounting and balancing.

What vehicles use 33x12.50R20 tires?

33x12.50R20 is original equipment on Ford F-150 (2015-2024, 20 in upsize), Ram 1500 (2009-2024, 20 in upsize), Chevrolet Silverado 1500 (2014-2024, 20 in upsize), GMC Sierra 1500 (2014-2024, upsize), Toyota Tundra (2007-2024, 20 in upsize), Jeep Wrangler JL/Gladiator (2018-2024, 20 in wheels) and Ford F-250 (2005-2024, 20 in no-lift upsize), 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 33x12.50R20 tire?

For most drivers our mid-range pick, the Falken Wildpeak A/T4W, 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 33x12.50R20 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.
