About the LT265/70R18 size
Load range E GM HD 18 in size (32.6 in). Highway and A/T tread with 124 load index; about 60 lb per tire.
What the numbers on the sidewall mean
A LT265/70R18 tire is 265 millimeters wide, its sidewall is 70 percent of that (about 7.3 inches tall), and it mounts on a 18-inch wheel. That works out to an overall diameter of roughly 32.6 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.

The same tires in neighboring sizes
The Ironman All Country A/T, our budget pick here at $238.96, is also stocked in LT245/75R16 ($197.96), LT265/75R16 ($206.96), 255/70R18 ($209.96) and 265/65R18 ($231.96).

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.
Of our picks in this size, the BFGoodrich All-Terrain T/A KO3 carries the 3PMSF symbol; the Ironman All Country A/T does not.

Frequently asked questions
How much do LT265/70R18 tires cost?
Expect $127–$175 per tire for a budget brand, $175–$258 for a mid-range tire like the Firestone Transforce HT2, and $258–$336 for a premium tire like the BFGoodrich All-Terrain T/A KO3. A set of four therefore starts at about $508. Add roughly $15 to $45 per tire for mounting and balancing.
What vehicles use LT265/70R18 tires?
LT265/70R18 is original equipment on Chevrolet Silverado 2500HD (2011-2019, LT/Z71 18 in), GMC Sierra 2500HD (2011-2019, SLE/SLT 18 in) and Chevrolet Silverado 3500HD SRW (2011-2019, 18 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 LT265/70R18 tire?
For most drivers our mid-range pick, the Firestone Transforce HT2, 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 Ironman All Country A/T is a sound choice.
Can I replace just one or two LT265/70R18 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.
