What is the original tire model of the Beijing BJ40?
3 Answers
The tire model of the Beijing BJ40 is 265/65R17. The first number, 265, indicates that the tire width is 265mm. The number 65 represents the aspect ratio of the tire's cross-section at 65%, meaning the section height is 65% of the width. The letter R stands for radial tire, and 17 indicates the rim diameter is 17 inches. The Beijing BJ40 has a top speed of 160km/h, accelerates from 0-100km/h in 4.2 seconds, and has a fuel consumption of 5.6L per 100km. In addition to the model, the tire also displays the following common data: Tire cord material: Indicated by Chinese pinyin, such as M for cotton cord, R for rayon cord, N for nylon cord, G for steel cord, and ZG for steel radial cord tire. Speed rating: Indicates the maximum speed at which the tire can carry a specified load under defined conditions. Letters from A to Z represent certified speed ratings ranging from 4.8km/h to 300km/h. Common speed ratings include: Q: 160km/h; H: 210km/h; V: 240km/h; W: 270km/h; Y: 300km/h. Rim specification: Indicates the rim size compatible with the tire for practical use, such as standard rim 5.00F.
The standard factory tires for the Beijing BJ40 are generally 265/70 R16 all-terrain tires. Based on my experience with many SUV configurations, this size indicates a tread width of 265 mm, an aspect ratio of 70%, and compatibility with 16-inch rims. The factory usually equips them with brands like Giti, designed to balance on-road and light off-road performance, offering stable fuel consumption but slightly higher noise at high speeds. As an owner, it's essential to regularly check tire pressure (recommended 2.2-2.5 bar) to prevent excessive wear that could affect handling safety. The tire choice for the BJ40 directly impacts vehicle performance—the factory configuration is sufficient for most daily road conditions. However, if frequently driving on mud or rocks, upgrading to more suitable AT tires is advised to extend service life. During maintenance, monitor wear indicators and inspect/replace tires approximately every 60,000 kilometers.
I've been driving the BJ40 for several years, which came with 265/70 R16 tires from the Giti brand. These tires perform well on paved roads with strong grip but are not very wear-resistant. I feel some bumpiness on uneven roads. Maintenance is simple; I make it a habit to check the tire pressure monthly, keeping it around 2.3 bar. For the average car owner, they are sufficient for weekend outings and city commuting, with good fuel efficiency. If considering a replacement, I would recommend high-quality tires of the same size and advise against unnecessary upgrades to avoid wasting money. Over long-term use, the original tires have proven reliable, but don't overlook regular adjustments.
