How many kilograms does an 825 tire weigh?

Brands and ply ratings vary, leading to differences in weight without a unified standard. Below is an introduction to tires: 1. Overview: Tires are circular elastic rubber products mounted on various vehicles or machinery for ground rolling. 2. Usage: Tires are typically installed on metal rims to support the vehicle body, cushion external impacts, ensure contact with the road, and maintain driving performance. 3. Function: Tires often operate under complex and demanding conditions, enduring various deformations, loads, forces, and temperature extremes during use. Therefore, they must possess high load-bearing, traction, and cushioning capabilities. Additionally, they require high wear resistance, flexibility, and low rolling resistance with minimal heat generation.
As a veteran heavy truck driver with years of experience, I often use 825 tires, each weighing around 350 jin (approximately 175 kg). These tires are extremely heavy, requiring two or three people to move them safely. Trying to handle them alone can easily lead to injuries, especially during replacement when specialized tools are necessary to prevent accidents. The weight varies depending on the brand and type. For instance, Michelin tires are heavier, around 380 jin, offering durability but consuming more fuel. Standard brands are lighter, about 320 jin, more economical but with a shorter lifespan. The weight also impacts driving: heavier tires provide better cushioning and less bumpiness but increase the vehicle's weight, leading to a fuel consumption rise of over 5%, which is particularly noticeable on long trips. During maintenance, it's crucial to note that uneven weight distribution can cause faster hub wear. I check tire balance every six months to extend their service life. When selecting tires, always refer to the manual to avoid overweight issues that could compromise safety.
I have worked in an auto repair shop for many years, frequently handling the replacement of 825 tires, with individual weights ranging from 150 to 200 kilograms, or 300 to 400 jin. The specifics depend on the specifications: the standard weight of the 825R20 model is approximately 180 kilograms or 360 jin. The tire structure also affects weight—steel-belted tires are heavier but offer stronger impact resistance, while nylon tires are lighter but more prone to aging. The weight directly impacts installation, requiring the use of pneumatic lifting equipment to prevent damage. Excessive weight can increase the burden on the suspension, shorten the lifespan of the wheel hub, and cause issues like vehicle misalignment or longer braking distances. I recommend that vehicle owners assess tires by measuring tire pressure and checking wear patterns, avoiding the temptation to save money by choosing inferior tires that pose safety risks. In daily maintenance, using professional equipment like hydraulic jacks can reduce manual labor and ensure smooth tire replacement.
