What 275/70R18 tires means
Reading the code left to right tells you the exact geometry of the tire. The 275 is the section width in millimeters (about 10.83 inches across the tread). The 70 is the aspect ratio, meaning the sidewall height is 70% of that width — roughly 192.5 mm, or 7.58 inches tall. The R means radial construction, and 18 is the wheel diameter in inches this tire mounts to.
Add it up and the overall diameter works out to about 33.16 inches, and the tire turns roughly 608 revolutions per mile. Those numbers matter to you in real ways: overall diameter affects speedometer accuracy and fender/suspension clearance, the tall 7.58-inch sidewall cushions bumps for a more forgiving ride, and revolutions per mile ties into gearing and how your dash reads at speed. If you switch to this size from a different diameter, your speedometer reading will shift accordingly.
Vehicles & uses
This is a light-truck and SUV size. Across the market it shows up most often on full-size pickups, larger crossovers, and body-on-frame SUVs, and it's offered widely in all-season, all-terrain, and mud-terrain builds. That breadth means the same 275/70R18 shopping list can cover a daily-driver highway setup or a weekend off-road rig — check your vehicle's placard or owner's manual for the size and load your truck was designed for before buying.

How to choose
Season: all-season tires handle most year-round driving; all-terrain adds bite on gravel and light mud; mud-terrain maximizes off-road grip at some cost to road manners; and dedicated winter tires are the pick for deep snow and ice.
Treadwear & UTQG: the UTQG treadwear grade printed on the sidewall is a relative durability indicator — higher numbers generally suggest longer tread life, with traction and temperature grades alongside it.
Load index & speed rating: the number-and-letter after the size (for example the 116 and its letter) states how much weight each tire can carry and its rated speed. Never go below what your vehicle's placard calls for — this is especially important on trucks that tow or haul.
Warranty: many all-season and all-terrain models carry a mileage treadwear warranty; confirm the coverage on the individual product page before you buy.
