What is the difference in centimeters between 10-inch and 12-inch tires?
2 Answers
10-inch and 12-inch tires have a radius difference of 1.65cm. Below is a detailed introduction to car tire specifications: 1. Specification model representation: Tires are important components of a car, and there are many specification models for tires, with different models suitable for different types of vehicles. The specification model identification is usually on the sidewall of the tire, represented by a series of alphanumeric characters, corresponding to the tire's tread width, aspect ratio, type, rim size, load index, and speed rating. 2. Speed rating: Based on the maximum speed they can withstand, tires can be divided into different speed ratings from A to Z, with the A grade further divided into eight levels from A1 to A8. Generally, the further back the letter representing the tire's speed rating is in the alphabet, the better the tire's performance.
I've been helping a friend choose electric scooter tires recently and noticed the difference between 10-inch and 12-inch sizes. A quick calculation: 12-inch minus 10-inch equals a 2-inch difference. Since 1 inch equals 2.54 cm, 2×2.54=5.08 cm. This seemingly small size difference makes a noticeable impact on the vehicle. If you choose the wrong tire size when replacing, the vehicle's handling will deteriorate. For example, slightly oversized tires on a small electric scooter can make it feel unstable when riding and affect its range. Personally, I've found that 12-inch tires offer better stability on flat surfaces but struggle with hills, while 10-inch tires are lighter but bumpier. I recommend measuring your vehicle's frame compatibility before selecting tires—don't cut corners and regret it later. Similarly, for bicycles or children's bikes, even a slight size mismatch can make the vehicle wobble and feel unstable. Checking specifications before installation is always a good practice.
