What Does LT Mean on a Tire

The first time most people notice “LT” on a tire, it’s usually while standing in a tire shop or scrolling online for replacements—then the confusion hits. Is this a size? A brand? Some kind of code? You’re not alone.

Tire sidewalls are packed with letters and numbers that feel like a secret language. Once you learn what they mean, though, choosing the right tire becomes way easier (and safer).

Quick Answer:
LT on a tire means “Light Truck.” It indicates the tire is built for trucks, SUVs, and vehicles that carry heavier loads, offering stronger construction than regular passenger tires.

What Does LT Mean on a Tire?

LT stands for Light Truck. When you see it at the beginning of a tire size—like LT265/70R17—it tells you the tire is designed specifically for light trucks, pickups, large SUVs, and commercial vans.

LT tires are built tougher than standard passenger (P) tires. They have stronger sidewalls, higher load-carrying capacity, and are better suited for towing, hauling, or off-road driving.

Simple example:
If your truck regularly tows a trailer or carries heavy equipment, an LT tire helps handle that extra stress safely.

In short:
LT = Light Truck = Tire built for heavier loads and tougher use.
