Haval H8's tire model is 255/50R19. The first number 255 indicates the tire width is 225MM, 50 means the tire's aspect ratio is 50%, that is, the section height is 50% of the width, and 19 represents the rim diameter is 19 inches. The middle letters or symbols have special meanings: "X" indicates high-pressure tires; "R", "Z" indicate radial tires; "-" indicates low-pressure tires. The fuel consumption of Haval H8 is 9.5L per 100 kilometers. In addition to the model, the following common data are also marked on the tire: Tire cord material: represented by Chinese pinyin, such as M-cotton cord, R-rayon cord, N-nylon cord, G-steel cord, ZG-steel radial cord tire. Speed rating: indicates the maximum speed at which the tire can carry the specified load under specified conditions. Letters A to Z represent the certified speed ratings of tires 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 specification matching the tire. For practical use, such as "Standard rim 5.00F".

I've been driving this Haval H8 for three years, and it came with factory-fitted 235/60 R18 tires. Once when I went to change tires, the mechanic mentioned that the higher trim version uses 255/50 R19 tires, which are wider and provide better stability at high speeds. I always pay special attention to tire condition during regular maintenance, as they are the only parts directly in contact with the road. The combination of numbers and letters in the tire model is actually quite interesting - 235 refers to the tread width of 235mm, 60 represents the aspect ratio, and R18 indicates the rim size. If you're replacing tires yourself, it's best to stick with the factory specifications, as using different sizes might affect the accuracy of the speedometer display. By the way, remember to adjust tire pressure seasonally - the manufacturer recommends a cold tire pressure of around 2.3 Bar.

The Haval H8 comes with two tire options depending on the trim: 235/60 R18 for the base model and 255/50 R19 for the high-end version. In these codes, the 'R' stands for radial tires, while the numbers 18/19 indicate the wheel diameter in inches. When selecting tires, don't just focus on the size—also pay attention to the speed rating symbol (like 'H' for 210 km/h) and load index. I recommend checking the tire wear indicators every six months; replace the tires when the tread depth falls below 1.6mm. The factory-fitted tires prioritize comfort and quietness, but if you frequently drive on mountain roads, you might consider switching to all-terrain tires. However, avoid arbitrarily changing the tire size specifications, as oversized wheels may interfere with suspension components.

The sidewall of the tire is engraved with the complete model. My H8's original tire specification is 235/60R18 103H. This type of tire is quite common in the market, with compatible models available from Michelin or Goodyear. When selecting tires, pay attention to the production date (a four-digit number like 0623 indicates the 6th week of 2023), and avoid buying tires that have been in stock for over three years. The tire width affects the contact area; too wide will increase fuel consumption, while too narrow will reduce grip. Once when I was changing tires, the mechanic measured the wheel's ET value with a vernier caliper and said that if the deviation exceeds 5mm, a spacer would be needed. Remember to remove small stones from the tire grooves during regular car washes to extend tire life.
