Can the tire aspect ratio be changed from 55 to 60?

Tire aspect ratio can be changed from 55 to 60, which does not have a significant impact on the vehicle. Here are specific details about tire aspect ratio: 1. Aspect ratio is a tire specification, simply referring to the ratio of tire width to height. After changing from 55 to 60, the tire sidewall becomes thicker, increasing vehicle comfort by filtering out minor bumps during driving. However, tire grip may decrease, though this varies by vehicle model. 2. An increased aspect ratio means the height-to-width ratio changes. A smaller aspect ratio indicates a flatter tire, resulting in better stability and stronger grip. With increased contact area, the vehicle can bear greater loads. For improved stability, it's recommended to use tires with lower aspect ratios. 3. There's no absolute good or bad in aspect ratio. For better handling and performance, flatter tires are suggested. For economy and comfort, thicker sidewall tires with stronger cushioning capability are preferable.
From my experience, changing the tire aspect ratio from 55 to 60 is possible, but requires caution. This modification will slightly increase the sidewall height, theoretically improving comfort by absorbing road vibrations better, which might make long-distance driving more comfortable. However, there's a major issue: the overall diameter will increase slightly, potentially causing speedometer and odometer inaccuracies. For instance, when it shows 100 km, you might actually be traveling only about 95 km, leading to risks of speeding or miscalculating maintenance intervals. I've also encountered cases where wheel arch clearance became insufficient, causing tires to rub against the body during high-speed cornering - a dangerous situation. For safety, always verify wheel compatibility, such as checking if the offset values match. It's best to use online tools to calculate the new tire's diameter change, ensuring it doesn't exceed the manufacturer's recommended range, or have a professional mechanic measure it with specialized tools for absolute certainty. Don't compromise safety for cost savings - accidents aren't worth the risk.
