What 275/65R18 tires cost

Falken Wildpeak A/T4W
The value sweet spot: long mileage warranty, solid wet grip, sane price.

BFGoodrich All-Terrain T/A KO3
Best wet and snow braking, quietest ride, longest tread life. Worth it if you keep the car.

About the 275/65R18 size
The top half-ton 18 in size (32.1 in), S/T rated in P-metric and load range C/E in LT. Every A/T and highway line; 275/70R18 (33 in) is the usual upsize.
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.

What is the best 275/65R18 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 Ironman All Country A/T is a sound choice.
Can I replace just one or two 275/65R18 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.
