325/50R20 Tire Width
How wide is 325/50R20 tire? Tire width is the measurement of the tire's cross-section at its widest point. 325/50R20 tire is 325 millimeters or 12.8 inches wide.
Tires that are 325 millimeters wide come equipped on a variety of pickup trucks and sport utility vehicles.
Tire width of 325 millimeters falls under extra wide category. For trucks and SUVs, extra wide tires offer enhanced stability and load-carrying capacity. For high-end sports cars and supercars they offer maximum traction and performance at high speeds.
Tire width plays a pivotal role in determining a vehicle's handling, safety, and efficiency. It is crucial to consider the compatibility of tire width with the vehicle's design and the manufacturer's specifications to maintain optimal functionality and ensure safety.
325/50R20 Aspect Ratio
Tire aspect ratio represents the height of the tire's sidewall as a percentage of its width. 325/50R20 tire size has an aspect ratio of 50%.
Tires with an aspect ratio of 50 fall into the category of low profile tires. These are commonly found on sports cars and high-performance luxury vehicles. The low profile (short sidewall height relative to tire width) enhances the vehicle's handling and responsiveness, particularly at high speeds and during sharp cornering. They contribute to a car's aggressive and sporty aesthetic.
Wider contact patch with the road surface allows for better traction, which is crucial for acceleration, braking, and cornering performance. However, it may also lead to increased road noise and a decrease in fuel or energy efficiency compared to tires with higher aspect ratios.
325/50R20 Rim Diameter
Rim diameter refers to the diameter of the wheel on which the tire is mounted, commonly measured in inches. 325/50R20 rim size is 20 inches, meaning that tire can be mounted on 20-inch wheels. Rim diameter directly correlates with the overall diameter of the tire and affects various aspects of vehicle performance and aesthetics.
Tires with rim diameter of 20 inches are equipped on a select crossover, minivan, passenger car, pickup truck, sport utility vehicle and van models.
20-inch rims are often used on high-end SUVs, light trucks, or high-performance sports cars. 20-inch rims are usually chosen for aesthetic reasons, or to accommodate larger, more robust tires needed for off-road or heavy-load conditions.
When selecting a rim diameter, it's crucial to consider the vehicle's design specifications, as altering the rim size can affect the speedometer and odometer calibration, vehicle handling, suspension geometry, and brake clearance.
325/50R20 Tire Diameter
How tall is 325/50R20 tire? Tire diameter represens the total height of a tire, including the rim, when it is fully inflated and not under load. 325/50R20 diameter is 834 millimeters or 32.8 inches.
Tire height affects the clearance between the tire and the vehicle's body or chassis, influences the vehicle's ground clearance, and can impact the accuracy of the vehicle's speedometer and odometer.
For standard passenger cars, tire diameters typically range from about 24 to 30 inches. This includes sedans, hatchbacks, small SUVs, and minivans. Light trucks and larger SUVs might have tires on the higher end of this range or slightly above, often between 29 to 33 inches. Sports cars and high-performance vehicles may have similar diameter ranges as standard passenger cars, but they often feature wider tires with a lower aspect ratio, which can slightly affect the overall diameter. The range for these vehicles is typically between 24 to 30 inches, focusing more on width and profile for performance. Off-road vehicles, including larger SUVs, trucks, and specialized vehicles, often have larger tire diameters to handle rough terrain better. The diameters for these vehicles can range from about 31 to 40 inches or more, depending on the level of off-road capability and customization.
325/50R20 Sidewall Height
Tire sidewall height, determined by the aspect ratio of a tire, represents the height of the tire's sidewall, measured from the edge of the rim to the top of the tread. 325/50R20 tire sidewall is 163 millimeters or 6.4 inches tall.
Sidewall height affects the tire's ability to dissipate heat and impacts its load-bearing capacity. It also plays a role in aesthetic appeal for many drivers, influencing the overall look of the vehicle.
Tires with a sidewall height of 6.4" are considered high profile. Higher sidewall offers better ride comfort and is more forgiving on rough surfaces. These characteristics are desirable in off-road, utility vehicles, and everyday passenger cars, as the increased sidewall height provides better shock absorption and protection against potholes and other road imperfections
325/50R20 Circumference
Tire circumference is the total distance around the outer edge of the tire. 325/50R20 tire has a circumference of 2619 millimeters or 103 inches.
Tires with a circumference of 103 inches are typically used on light trucks and SUVs, sports and performance cars. For trucks, the larger circumference is beneficial for off-road performance, providing greater traction and a smoother ride over rough terrain. The downside is often reduced fuel efficiency and potentially slower acceleration due to the larger size and weight of the tires. For sports and performance vehicls, the benefit here is enhanced grip and handling for high-speed driving, although ride comfort might be compromised due to the lower profile associated with these tires.
Tire circumference directly influences the speedometer and odometer readings of a vehicle. Mismatched tire circumferences, especially on the same axle, can lead to uneven wear, handling issues, and even mechanical damage, particularly in all-wheel or four-wheel-drive vehicles.
325/50R20 Revolutions
Tire revolutions metric reflects the number of times a tire rotates over a fixed distance. This figure is inherently tied to the tire's circumference - the larger the circumference, the fewer the revolutions needed to cover a mile, and vice versa. 325/50R20 tire makes 382 revolutions per kilometer or 615 revolutions per mile.
Number of the revolutions a tire makes affects greatly vehicle's performance, from speed and distance measurement accuracy to handling, fuel efficiency, and wear and tear.

What is LT325/50R20 in inches?
When converted to inches, LT325/50R20 tire size is equivalent to 32.8x12.8R20. 32.8 inches indicate the tire diameter, 12.8 inches represent tread width, and 20 inches is the diameter of a rim the tire can be mounted on.
Conversion of LT325/50R20 to inches involves a series of steps that translate the metric measurements of tire width, aspect ratio, and rim diameter into their inch equivalents. This conversion is crucial for understanding tire sizes in a format that may be more intuitive or necessary for specific applications, allowing for better informed decisions regarding tire selection and compatibility.
First, the width of the tire (325 mm) is converted to inches by dividing by 25.4 (since there are 25.4 millimeters in an inch). Secondly, to determine the sidewall height in inches, calculate the height of the tire's sidewall as a percentage of its width (the aspect ratio), then convert this measurement from millimeters to inches. In the case of a LT325/50R20 tire, the sidewall height is 50% of 325 mm, which converts to approximately 6.4 inches. Lastly, to ascertain the overall diameter of the tire, sum twice the sidewall height with the diameter of the rim (already in inches). Therefore, for a LT325/50R20 tire, the overall diameter is the sum of twice the sidewall height (6.4 x 2) plus the rim diameter (20 inches), culminating in an overall diameter of about 32.8 inches.
