What is the tire size of the GS4?
3 Answers
The GS4 has two tire sizes: 225/60R17 and 225/55R18. In 225/60R17, the first number 225 represents the tire width of 225MM, 60 indicates the aspect ratio of the tire section is 60%, meaning the section height is 60% of the width, 17 stands for the rim diameter of 17 inches, and the letter "R" in the middle denotes a radial tire. In 225/55R18, the first number 225 represents the tire width of 225MM, 55 indicates the aspect ratio of the tire section is 55%, meaning the section height is 55% of the width, 18 stands for the rim diameter of 18 inches, and the letter "R" in the middle denotes a radial tire. The GS4 tires feature a five-spoke wheel rim design, giving a more powerful appearance, and are matched with Giti Comfort-F50 tires. The spare tire is non-full size. If you want to replace the tires yourself, you can follow these steps: Take out the spare tire and jack, place the jack under the vehicle frame near the tire to be replaced, ensuring the jack touches the metal part of the frame; Raise the jack until it supports the car, the jack should be positioned under the vehicle, check and ensure the jack is at a right angle to the ground; Remove the hubcap, loosen the nuts counterclockwise, do not fully loosen them, just enough to eliminate resistance. When loosening the nuts for the first time, keeping the tire on the ground ensures that the nuts turn, not the tire; Turn the nuts counterclockwise until they are loose, repeat this step for all lug nuts, then completely remove the nuts; Place the new tire on the hub, carefully align the tire rim with the wheel bolts, install the lug nuts, and tighten them by hand until all nuts are snug. At this point, the tire replacement is complete. In addition to the model, the tire also has the following common data marked on it: Tire cord material: Indicated 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 a 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 compatible with the tire. For practical use, such as "Standard rim 5.00F".
The tire size of the GAC GS4 SUV is no small matter. I remember my base model came with factory-fitted 225/60R17 tires, featuring 17-inch rims, a width of 225 millimeters, and an aspect ratio of 60%. This size offers a well-balanced drive, combining comfort with solid grip. For higher trims like the Intelligent Connect version, the wheels might be upgraded to 225/55R18, with slightly thinner tires for added stability. After buying my car, I did some research—choosing the wrong size can be frustrating. Low tire pressure on long trips can increase fuel consumption, while high pressure makes the ride bumpy, so I regularly check and maintain my tire pressure at 2.2-2.4 bar. Larger wheels look stylish but must match the factory specifications to avoid higher risks of skidding during turns. In short, it’s best to check the manual or confirm with the dealership based on your model’s configuration. Avoid random modifications to ensure safety.
When it comes to the tires of the GS4, I've seen many examples during car repairs: the standard version uses 225/60R17 tires, while higher-end models like the luxury version come with 225/55R18 sizes. The key point here is that the wheel and tire sizes must match for stability, with a width of 225 millimeters—don’t overlook the aspect ratio data, as even a slight difference can affect braking distance and comfort. Incorrect tire pressure, such as below 2.0 bar, can cause instability during high-speed cornering; if it’s too high, hitting bumps may lead to blowouts. It’s recommended that owners check tire pressure during every maintenance session and inspect tire wear. If the tread depth is less than 1.6 mm, it’s time to replace them—opt for original specifications or reputable brands like Michelin to avoid refurbished products. Getting the wrong size can be troublesome.
