Understanding Tire Sizes
Understanding the information on your vehicle's tire sidewall is crucial for maintaining safety and optimal performance. The series of numbers and letters on the tire provide vital details about its size, type, and capabilities. Below, we'll break down each element of the tire size information, explaining what each component means and why it matters. Whether you're looking to replace your tires or simply want to decode the markings on your current set, this information will empower you with the knowledge needed to make informed decisions about your vehicle's tires.
Tire Type/Metric
The first letter in a tire size represents the tire type or application for which the tire is designed. It provides information about the intended use and performance characteristics of the tire. Here are some common tire type designations indicated by the first letter:
- P: Passenger Car Tire. The "P" indicates that the tire is designed for use on passenger cars, SUVs, and light trucks. These tires are typically optimized for comfort, ride quality, and everyday driving.
- LT: Light Truck Tire. "LT" stands for Light Truck, and these tires are designed for light trucks, SUVs, and other larger vehicles. They often have higher load-carrying capacities and are built to withstand heavier loads and more rugged conditions.
- T: Temporary Spare Tire. The "T" indicates that the tire is a temporary spare tire designed to be used only for short distances at lower speeds. These compact spare tires are not meant for extended use but are intended to get you to a service center to repair or replace a damaged tire.
- ST: Special Trailer Tire. "ST" tires are designed specifically for trailers, such as travel trailers, boat trailers, and utility trailers. They are constructed to handle the unique demands of towing, including higher load capacities and stability requirements.
- C: Commercial Tire. The "C" denotes commercial tires designed for commercial vehicles, vans, and delivery trucks. These tires often have reinforced construction to handle heavier loads associated with commercial use.
- HP/HR/VR/ZR/W/Y: Performance Tires. These letters indicate various high-performance tire categories, often found in performance-oriented cars. For instance, "H" represents high-performance, "V" stands for higher-speed performance, "ZR" indicates a tire with a speed capability above 149 mph, and so on.
These designations help you understand the primary purpose and characteristics of the tire before looking into the rest of the tire size information. Keep in mind that the tire type, along with other specifications like tire size, load index, and speed rating, should be considered when choosing the right tire for your vehicle and its intended use.
Tire Width
Tire width refers to the measurement of the tire's cross-sectional width from one sidewall to the other, expressed in millimeters. It's the distance between the widest points of the tire when viewed from above. The tire width is a critical factor in determining how the tire performs in terms of handling, stability, and grip. Wider tires generally offer better traction and grip, but they can also affect fuel efficiency and ride comfort. The tire width is one of the components specified in the tire size, such as "225/50 R17," where "225" represents the width in millimeters.
Aspect Ratio
A tire's aspect ratio refers to the ratio of the tire's sidewall height to its width, typically expressed as a percentage. It indicates how tall the tire's sidewall is in relation to its width. A lower aspect ratio (e.g., 50) means the sidewall is shorter, resulting in better handling and cornering but potentially a slightly rougher ride. A higher aspect ratio (e.g., 70) indicates a taller sidewall, which can enhance ride comfort and absorb road irregularities. The aspect ratio is the second component in the tire size, such as "225/50 R17," where "50" represents the aspect ratio.
Tire Construction
Tire construction refers to the internal structure and design of the tire. The most common type is radial construction, where the tire's internal layers (ply cords) run radially from the center of the tire. This construction offers improved performance, fuel efficiency, and ride comfort. Other less common types include bias-ply construction, where the ply cords criss-cross diagonally, offering durability but with less modern performance. The tire's construction type is often indicated by a letter in the tire size, such as "R" for radial.
Rim Diameter
Rim diameter refers to the measurement of the inner diameter of the tire, which matches the outer diameter of the rim it's designed to fit on. It's expressed in inches and helps ensure that the tire properly fits the rim. The rim diameter is a critical factor in determining the overall tire size compatibility with a specific vehicle. It's the last component specified in the tire size, such as "225/50 R17," where "17" represents the rim diameter in inches.
Load Index
The load index of a tire is a numerical code that indicates the maximum weight the tire can safely carry when properly inflated. It's a standardized value that corresponds to a specific weight capacity. Higher load index values represent higher weight capacities. Knowing the load index helps ensure that the tires you choose can handle the weight of your vehicle and its load without risking safety or tire damage.
Speed Rating
Speed rating for a tire is a letter code that indicates the maximum speed the tire is designed to handle safely under optimal conditions. It provides information about the tire's performance capabilities at higher speeds. It's important to choose tires with a speed rating that meets or exceeds the speeds you intend to drive, but remember that other factors like load capacity and road conditions also play a role in tire safety and performance.
Factory Tread Depth
The Factory Tread Depth is considered the "new" tread depth reading of a given tire, as specified by the manufacturer.
Minimum Tread Depth
The minimum legal Tread Depth. Review local regulations for more in-depth recommendations.
Life Expectancy
The Life Expectancy or "Warranty" of a tire is the expected meter range, usually measured in miles, of a given tire as specified by the manufacturer.

View, Filter, Bulk Update & VIN Decode from the Vehicle Index
View
On the Vehicle Index, you will see columns for Installed Tires and Axle Configuration.
TIP: If you don't see these columns, click the Manage Columns icon on the right of the index. Here, you can enable these columns and reorder, as needed.
Click the number of Tires Installed to be taken to the Tire Management module where you can view more specifics about the tires.
If you hover over the number of installed tires, you will see the tire types that have been installed.

Clicking the tire types will take you directly to the Part in Fleetio, if the tires were previously added through Parts.
Filter
If you would like to filter the Vehicle Index by vehicles with a specific axle configuration, or by vehicles that are missing an axle configuration, you may do this by clicking filter and choosing Vehicle Axle Configuration.

Bulk Update
After you filter the Vehicle Index, you may want to update the axle configurations for vehicles in bulk. To do this, select the vehicles by clicking the checkboxes on the left, and using the Actions menu to select Update Vehicles.

Select Axle Configuration under the Field Column. Under Value, select Replace with and select the appropriate axle configuration you want to apply to all selected vehicles..
