What size is a 275/80r22.5 tire?

275/80r22.5 indicates: The tire width is 275 millimeters, the aspect ratio is 80, and it can be mounted on a 22.5-inch rim. The aspect ratio is a tire specification that refers to the percentage of the tire's cross-section height to its maximum cross-section width, which is the height-to-width ratio of the tire. Tires with a high aspect ratio have longer sidewalls and better cushioning capabilities, offering relatively higher comfort but poorer road feel and weaker lateral resistance during turns. Conversely, tires with a low aspect ratio and large inner diameter have shorter sidewalls and wider treads, resulting in a larger contact area. These tires can withstand greater pressure, provide very sensitive road feedback, have strong lateral resistance during turns, and enhance vehicle handling.
The tire size 275/80R22.5 refers to a tread width of 275 millimeters, with an aspect ratio of 80%, meaning the sidewall height is 80% of the width, approximately 220 millimeters high, paired with a 22.5-inch wheel. The total height is about 1012 millimeters, roughly 39.8 inches. I often deal with various vehicle models, and this size is commonly used for medium-duty trucks or buses because it can carry heavy loads, with large wheels providing strong support, ensuring stability and reliability during long-distance transportation. However, it's important to note the larger turning radius can easily scrape the chassis, so extra space should be reserved for parking. Regular tire pressure checks can extend the tire's lifespan and prevent blowout risks, especially when carrying loads—never exceed the weight limits.
I've driven many large vehicles with 275/80R22.5 tires. The 275mm width is about half the length of an adult's arm, while the 220mm sidewall height resembles a short bucket. The 22.5-inch rims are noticeably larger than those on sedans and are commonly used on trucks or heavy-duty vehicles. In practice, the wide tread provides stable grip, better shock absorption on rough terrain, and reduced bumpiness, making the ride relatively comfortable and safe. However, these tires tend to have higher fuel consumption and wear out faster. It's advisable to check wheel balance every six months to prevent vibrations. Opting for durable tire models during selection can save money and ensure peace of mind.
This size features a 275mm tire width, with an 80 aspect ratio calculating to a sidewall height of 220mm, mounted on 22.5-inch rims for a total height of approximately 40 inches. I've commonly seen commercial vehicles like delivery trucks or school buses using such tires - they offer excellent load-bearing capacity suited for heavy-duty high-speed operations, providing stable handling and good maneuverability. However, they require regular maintenance to prevent air leaks, and drivers should slow down when encountering potholes to protect the chassis.
