Xiaomi YU7 245/55R19 Tire Specs Explained
Q: What do the numbers 245 and 55 represent in Xiaomi YU7’s 245/55R19 tires? Why wasn’t 255-width chosen?
A: “245mm” indicates the tire’s section width – the straight-line distance between sidewalls at their widest point. “55” is a percentage representing the sidewall height relative to section width. Higher aspect ratios mean thicker-looking tires with better impact resistance, protecting rims while enhancing comfort and cushioning.
The 245mm width also boosts range, helping the standard model achieve up to 835km CLTC range while balancing comfort and efficiency. The 245/55 combination is typical for comfort-oriented models preserving some driving dynamics. Compared to 255/50 tires, this sacrifices some handling for superior comfort and range.
For safety, Xiaomi YU7 features custom tire tuning with ESP stability control and quadruple braking redundancy. Driving stability depends not just on tire width but systemic calibration.
For better handling, rear tires support up to 275/40 R21 (front-narrow/rear-wide configuration). Xiaomi YU7 offers multiple wheel/tire options catering to range, comfort, quietness, and sportiness – details will follow.
