220/55R390 Tire Width
How wide is 220/55R390 tire? Tire width is the measurement of the tire's cross-section at its widest point. 220/55R390 tire is 220 millimeters or 8.7 inches wide.
Tires with width of 220 millimeters are considered fairly wide. This width offers enhanced traction and stability, which is crucial for handling heavier vehicles or providing better performance and driving dynamics.
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.
220/55R390 Aspect Ratio
Tire aspect ratio represents the height of the tire's sidewall as a percentage of its width. 220/55R390 tire size has an aspect ratio of 55%.
Tires with an aspect ratio of 55 represent a category that balances performance with comfort, making them suitable for a wide range of vehicles. This tire width is particularly common in modern passenger cars, including sedans, coupes, crossovers and SUVs.
Tires with this aspect ratio offer a good compromise between the agile handling of lower profiles and the increased comfort of higher profiles. They are designed to meet the needs of drivers who want a blend of comfort, handling, and aesthetic appeal.
220/55R390 Rim Diameter
Rim diameter refers to the diameter of the wheel on which the tire is mounted, commonly measured in inches. 220/55R390 rim size is 15 inches, meaning that tire can be mounted on 15-inch wheels. Rim diameter directly correlates with the overall diameter of the tire and affects various aspects of vehicle performance and aesthetics.
Rims with a 15-inch diameter are common on mid-size and full-size sedans, as well as some crossovers and SUVs. They offer a balance between ride comfort, handling, and aesthetic appeal.
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.
220/55R390 Tire Diameter
How tall is 220/55R390 tire? Tire diameter represens the total height of a tire, including the rim, when it is fully inflated and not under load. 220/55R390 diameter is 632 millimeters or 24.9 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.
220/55R390 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. 220/55R390 tire sidewall is 121 millimeters or 4.8 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 4.8" offer a balance between performance and comfort, and are common on popular sedans, minivans, light trucks and SUVs.
220/55R390 Circumference
Tire circumference is the total distance around the outer edge of the tire. 220/55R390 tire has a circumference of 1984 millimeters or 78.2 inches.
Tires with a circumference of 78.2 inches are typically found on small cars and compact vehicles. The advantage of smaller circumference tires is that they generally provide better fuel efficiency, enhanced acceleration and more responsive handling for easier maneuverability. However, they may offer less traction and a rougher ride compared to larger 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.
220/55R390 Revolutions
