What are the sizes of SUV tires?

[LeRhett]

SUV tires range in tread width from less than 6 inches to more than 10 inches. The selection depends on load rating, speed rating, and performance on slippery surfaces, with significant variations in tread design. Differences between sedan tires and SUV tires: Sedan tires mostly feature small patterns/blocks, with more densely spaced lateral grooves across the tire to enhance handling and reduce noise. SUV tires have deeper and wider tread patterns than sedan tires to maintain optimal traction. SUV tires generally have a higher aspect ratio. Additionally, SUV tires are significantly harder in tread hardness compared to sedan tires. Types of SUV tires: HT tires, AT tires, MT tires. HT tires: Among SUV tires, HT tires are the closest to sedan tires in terms of positioning and performance trade-offs. This type of tire is widely used in urban SUV models. AT tires: AT stands for all-terrain tires, meaning they can adapt to various road conditions. These tires offer more balanced performance, performing well on both paved and unpaved surfaces. MT tires: MT tires are the most niche category among SUV tires, often considered the 'special forces' of SUV tires.

I often modify SUV tires myself, with sizes ranging from the compact Jeep's 225/65R17 to the large seven-seater like the Land Rover Range Rover's 275/55R20. The size differences vary greatly depending on the vehicle model, similar to how the Honda CR-V commonly uses 235/60R18, while the Ford Explorer is often equipped with 265/60R18. The numbers on the tire size label represent width, aspect ratio, and rim diameter. Choosing the wrong size can easily affect stability and fuel consumption, so I always refer to the original manual when changing tires to avoid mistakes. Larger sizes are suitable for off-roading but increase wind resistance, while smaller sizes are more fuel-efficient for city driving. Regular wear checks are crucial, and aging tires should be replaced promptly to maintain driving pleasure and safety.

As a new driver, I was puzzled by the meaning of tire sizes when I first got my SUV. Common sizes like 235/55R18 indicate a width of 235 millimeters, an aspect ratio of 55%, and an 18-inch rim diameter. Different SUVs have standard sizes; for example, the Toyota RAV4 comes with 225/65R17, while the Nissan Pathfinder uses 255/55R20. Oversized tires can make steering heavier, while undersized ones may feel unstable and affect braking distance—I always check the sidewall labels during maintenance. SUV tires are generally larger than those on sedans to enhance grip and comfort, but off-roading requires caution to avoid rim damage from gravel. Regularly checking tire pressure can extend their lifespan, and consulting a repair shop for sizing issues helps avoid unnecessary hassle.

From a safety perspective, tire size is crucial for SUV driving. Size mismatches can lead to accidents, such as using 245/65R17 instead of the factory size, which may cause balance issues or increase the risk of blowouts. Common standards like the 225/65R17 for the Chevrolet Equinox or 285/70R17 for the Jeep Wrangler show how size differences directly affect handling stability and braking performance. I recommend checking tire wear and pressure monthly to ensure compliance with the vehicle manual. Larger sizes can enhance traction in off-road conditions, but for city driving, matching sizes should be chosen to reduce the risk of rollovers. Neglecting size maintenance increases driving hazards, making regular rotation a necessary measure.
