What is the rolling radius of a tire?

[AubreeMarie]

The rolling radius of a tire needs to be calculated based on the tire model. For example, the rolling radius of a 185/65-R15 tire is approximately 310.75mm, calculated using the formula (381 + 120.25 × 2) / 2 = 310.75mm. Below is some information about tires: 1. Introduction: A tire is a circular elastic rubber product mounted on various vehicles or machinery to roll on the ground. It is usually installed on a metal rim to support the vehicle body, absorb external shocks, ensure contact with the road surface, and maintain driving performance. 2. Required properties: Tires are often used under complex and demanding conditions, enduring various deformations, loads, forces, and high/low temperatures during operation. Therefore, they must have high load-bearing capacity, traction performance, and shock absorption. Additionally, they need to exhibit high wear resistance, flex resistance, and low rolling resistance with minimal heat generation.
