About the LT275/70R18 size
The dominant HD truck size, load range E (3,640 lb per tire at 80 psi). A/T, highway and commercial tread; most popular LT size in the US.
The numbers mean: 275 mm section width, sidewall height 70 % of that width, and a 18-inch rim. Overall diameter works out to about 33.2 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 LT275/70R18 tires cost?
Expect $152–$199 per tire for a budget brand, $199–$274 for a mid-range tire like the General Grabber X3, and $274–$377 for a premium tire like the Goodyear Wrangler All-Terrain Adventure with Kevlar. A set of four therefore starts at about $608. 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.
