What is the diameter of an 825r20 tire in centimeters?

20 inches. Below is an introduction about tires: 1. Introduction: A tire is a circular elastic rubber product assembled on various vehicles or machinery to roll on the ground. It is usually mounted on a metal rim, supporting the vehicle body, cushioning external impacts, achieving contact with the road surface, and ensuring the vehicle's driving performance. 2. Performance: Tires are often used under complex and harsh conditions, enduring various deformations, loads, forces, and high and low temperatures during operation. Therefore, they must have high load-bearing performance, traction performance, and cushioning performance. At the same time, they are also required to have high wear resistance and flex resistance, as well as low rolling resistance and heat generation.
I've been driving long distances for several years and always make sure to familiarize myself with tire sizes to avoid trouble. The 825r20 tire has a diameter of approximately 158 cm, which is easy to calculate: multiply the tire width of 825 mm by the standard aspect ratio of 65% to get a sidewall height of about 536 mm, then multiply by 2 and add the rim diameter of 508 mm to get a total length of 1580 mm. In actual driving, this value is crucial as it affects the vehicle's ground clearance and speedometer accuracy. When fitting new tires, I've measured them several times to ensure they don't scrape the chassis—brand variations like Michelin may deviate by 5 mm but generally stay within the 158 cm range. Remember, regular checks on tire pressure and wear can extend tire life and prevent blowouts at high speeds.
