About the LT275/65R18 size
Load range E F-250 size (32.1 in), 3,415 lb per tire. Slightly cheaper than LT275/70R18 with a wide A/T and highway selection.
The numbers mean: 275 mm section width, sidewall height 65 % of that width, and a 18-inch rim. Overall diameter works out to about 32.1 inches. Any replacement has to match all three, and the load index and speed rating on your door sticker must be met or exceeded. Our guide on reading a tire size walks through it.

Frequently asked questions
How much do LT275/65R18 tires cost?
Expect $133–$187 per tire for a budget brand, $187–$260 for a mid-range tire like the Cooper Discoverer AT3 LT, and $260–$351 for a premium tire like the BFGoodrich All-Terrain T/A KO3. A set of four therefore starts at about $532. Add roughly $15 to $45 per tire for mounting and balancing.
What vehicles use LT275/65R18 tires?
LT275/65R18 is original equipment on Ford F-250 (2011-2016, XLT/Lariat 4x4), Ford F-350 SRW (2011-2016) and Chevrolet Silverado 2500HD (2011-2019, LTZ 18 in 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 LT275/65R18 tire?
For most drivers our mid-range pick, the Cooper Discoverer AT3 LT, 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 LT275/65R18 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.
