Capacity and pressure
Use the exact tire’s load-and-inflation table and stay within axle, wheel, and vehicle ratings.

Truck Tire Sizes
Truck tire selection starts with capacity, not appearance. LT construction, load range, load index, inflation tables, tread type, and actual axle loads all matter; a larger size does not automatically carry more weight or suit towing better.

Selection guide
Important Truck tire considerations
Towing stability
Construction stiffness and correct pressure matter alongside tread pattern and nominal size.
Unsprung mass
Heavier LT and off-road tires can reduce acceleration, braking response, and fuel economy.
Gearing
A taller diameter changes effective axle ratio, engine rpm, speedometer reading, and low-speed response.

Fitment limitations
A category label describes intended use, not guaranteed vehicle fitment. Confirm the door placard, approved wheel width, load index, speed rating, wheel offset, suspension clearance, and manufacturer guidance before changing size or construction.
