What is the difference between aspect ratios 50 and 45?

[MicahLynn]

The difference is not significant. A lower aspect ratio means the tire has better grip, clearer road feedback, stronger handling stability, and better acceleration performance. However, low aspect ratio tires have poorer comfort and are more suitable for sports models. They require higher road conditions and have relatively higher fuel consumption. High aspect ratio: Long sidewalls provide good vibration absorption and cushioning effects, offering excellent comfort. However, they have poor road feedback and weak lateral resistance during turns, resulting in poor handling. Do not change the aspect ratio: It is recommended not to alter the tire's aspect ratio, as changing the tire specifications can cause various issues, such as ABS failure, inaccurate odometer readings, transmission problems, and in severe cases, it may affect driving safety.
