An LT tires size is a metric tire designation that is mostly used on European passenger cars.

LT Tires
There are a lot of different LT tires on the market, but what size is an LT tire? The answer to that question depends on the size of your vehicle. LT tires are available in a variety of sizes, so you can find the perfect size for your car or truck.
P-Metric and LT-Metric Tires
P-Metric and LT-Metric tires are designed to offer a longer tread life than Standard tires. P-Metric tires have a higher ply rating than Standard tires to offer increased load-carrying capability. The intended use for P-Metric and LT-Metric tires is passenger cars, vans, and light trucks.
P-Metric tires are identified by the “P” in their size designation, while LT-Metric tires are identified by the “LT” in their size designation. For example, a P215/70R15 tire has a section width of 215 millimeters, aspect ratio of 70%, and is designed to fit a 15″ wheel. An LT235/75R15 tire has a section width of 235 millimeters, aspect ratio of 75%, and is designed to fit a 15″ wheel.
When shopping for new tires you may see reference to “LT Tires.” This generally refers to LT-Metric Tires, which are designed for light trucks.
Load Range
There are two main types of tires on the market today: passenger tires and light truck (LT) tires. Both tire types are designed to provide different levels of performance, comfort, and durability. So, what exactly is the difference between passenger and LT tires?
The biggest difference between passenger and LT tires is their load range. Load range is a measure of a tire’s strength and ability to carry weight. Passenger tires have a lower load range than LT tires, which means that they are not designed to carry as much weight.
If you’re considering purchasing LT tires for your vehicle, it’s important to know that there are three different load ranges: light duty (LD), standard duty (SD), and heavy duty (HD). LD LT tires are designed for vehicles that weigh up to 6,000 pounds. SD LT tires are designed for vehicles that weigh between 6,001 and 8,500 pounds. HD LT tires are designed for vehicles that weigh more than 8,500 pounds.
When choosing an LT tire for your vehicle, it’s important to select a tire with a load range that matches your vehicle’s weight. If you’re not sure what size tire you need, it’s always best to consult with a professional.
How to Read an LT Tire Size
The LT in the tire size stands for Light Truck. That means the tire is meant for trucks, vans, and SUVs. The numbers that come after the LT are important to know because they tell you the tire’s width, height, and diameter.
P-Metric and LT-Metric Tires
Most tires sold in the U.S. today are P-metric or LT-metric. P-metric tires are passenger car tires, while LT-metric tires are designed for light trucks. The letters “LT” in the tire size mean “light truck.” P-metric and LT-metric tires have certain characteristics in common, but there are also some important differences between them.
P-Metric and LT-Metric Tires: What’s the Difference?
Both P-metric and LT-metric tires have load indexes and speed ratings. The load index is a number that corresponds to the maximum weight that the tire can support when properly inflated. The speed rating is a letter that indicates the maximum speed at which the tire can be driven safely under normal conditions.
P-metric and LT-metric tires also share several other features, including tread width, sidewall height, and wheel diameter. But there are some important differences between P-metric and LT-metric tires, too. These include:
Tire construction: P-metric tires typically have radial construction, while LT-metric tires may have radial or bias ply construction. Bias ply construction is less common than it used to be, but it’s still found on some light truck tires.
Tread patterns: P-metric passenger car tires tend to have smooth tread patterns with few tread elements, such as ribs or sipes (slits in the tread). In contrast, LT-metric light truck tires often have more aggressive tread patterns with prominent tread elements that help provide traction in off-road conditions.
Load capacity: In general, LT-metric tires have higher load capacities than Pestle cairns do — meaning they can support heavier weights. This is one reason why light trucks need special tires; their increased weight places greater demands on the tire’s load capacity.
Load Range
The load range of a tire is an indication of how much weight the tire can support. The load range is indicated by a letter, with “A” being the lowest and “E” being the highest.
