What is the tire specification of Wuling Zhiguang?
3 Answers
There are two tire specifications for Wuling Zhiguang, namely 155R13LT and 165/70R13. In 155R13LT, the first number 155 indicates the tire width is 155MM, the middle letter "R" represents a radial tire, 13 indicates the rim diameter is 13 inches, and LT stands for light load tire. In 165/70R13, the first number 165 indicates the tire width is 165MM, 70 represents the aspect ratio of the tire section is 70%, meaning the section height is 70% of the width, 13 indicates the rim diameter is 13 inches, and the middle letter "R" represents a radial tire. Wuling Zhiguang rims are made of steel, which is economical and cost-effective, featuring a classic design. None of the models come with a spare tire as standard. If you want to replace the tires yourself, you can follow the steps below: Take out the spare tire and jack, place the jack under the vehicle frame of 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 hub cover, loosen the nuts counterclockwise, do not completely loosen the nuts, just enough to eliminate resistance. When loosening the nuts for the first time, keeping the tire on the ground ensures that the nuts turn rather than the tire; Turn the nuts counterclockwise until they come off, repeat this step for all lug nuts, and completely remove the nuts; Place the new tire on the rim, carefully align the tire rim with the wheel bolts, install the lug nuts, tighten the nuts by hand until all nuts are concealed, at this point the tire replacement is complete. In addition to the model, the tire is also marked with the following common data: 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 the tire 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".
I've been driving the Wuling Rongguang for several years, mainly for daily cargo hauling and commuting. The tire size is 165/70 R13, which is suitable for urban roads with stable grip and low fuel consumption. I remember the original factory tires were of good quality when I first bought it, and I always stick to the same size when replacing them because non-standard sizes may affect handling or fuel efficiency. I usually maintain the tire pressure around 2.4 bar, as too high or too low can cause wear or blowouts. Safety-wise, the right tire size ensures good braking performance, giving me peace of mind when driving in rain or snow. I recommend car owners regularly check the tread wear and replace the tires immediately if they are worn out—don’t skimp on small expenses. Economically, replacing tires of the same size is affordable in the market, and each replacement can last 40,000–50,000 km, offering great value for money.
The standard tire specification for the Wuling Zhiguang is 165/70 R13. The 165 represents the width in millimeters, 70 is the aspect ratio, R indicates a radial structure, and 13 inches is the wheel size. This combination offers numerous advantages, such as moderate width for better handling stability, while the 70 aspect ratio provides excellent shock absorption, ensuring a smooth ride on long journeys without excessive bumpiness. For the small-displacement design of this vehicle, the smaller tire size helps reduce wind resistance and improve fuel efficiency, allowing me to travel farther on each tank of fuel. When selecting tires, avoid the temptation to upgrade to larger sizes, as this may lead to overloading and safety risks. Additionally, be mindful to avoid driving on gravel roads to prevent punctures and extend tire lifespan. A related recommendation is to perform a wheel alignment every six months to prevent uneven wear and alignment issues.
