Cavalier uses the following two brands of tires: 1. Goodyear Assurance pattern series, with specifications of 205/55R16. 2. Giti Comfort 228 series, with specifications of 195/65R15. Information about car tires is as follows: 1. Function: Car tires are one of the important components of a vehicle. They directly contact the road surface and, together with the car suspension, help to cushion the impact during driving, ensuring good ride comfort and smoothness. They also ensure good adhesion between the wheels and the road surface, improving the car's traction, braking, and off-road capabilities, while bearing the weight of the car. 2. Common types: (1) Radial tires: The specifications of radial tires include width, aspect ratio, inner diameter, and speed limit symbols. (2) Tubeless tires: Commonly known as "tubeless tires." These tires are less prone to heat buildup during high-speed driving. When punctured by nails or sharp objects, they leak air slowly, allowing the car to continue driving for a certain distance.

Last time when helping my brother change tires for his Cavalier, I did some research and found the factory-fitted tires quite interesting. My 2019 model came with Maxxis WALTZ MS360, while my friend's newer one has Kumho SOLUS HS63. The automaker may switch suppliers for different production batches, so it's best to check the vehicle manual for confirmation. However, in recent years I've noticed many owners switching to Michelin ENERGY XM2+ - the 215/55 R16 size offers good compatibility and significantly improved wet road grip. When changing tires, don't just look at the brand. The load index (91V) and speed rating (V) marked on the tire sidewall are more crucial, especially for those who frequently drive on highways. Once I saw someone buy cheaper H-rated tires to save money, and the car became dangerously unstable at just 110 km/h.

With a decade of car repair experience, I've seen hundreds of Cruze tire configurations. GM's OEM tires prioritize cost control, initially using Hankook KINERGY EX and later switching to Nexen CP672 in subsequent batches—both are entry-level quiet tires. When replacing tires, I recommend prioritizing 205/60 R16 compatible models, which offer about 6% better fuel efficiency compared to the factory 215 tires. Last week, I installed four Dunlop ENASAVE EC300+ tires for a customer; their thickened sidewall design is ideal for damaged roads in urban-rural fringe areas, and the self-cleaning function for gravel in the tread grooves performs well on sandy or rocky terrain.

When I first bought the car, I was also confused about tire brands. Now I've figured it out: checking the tire pressure label on the left front door frame is the most accurate. The Cavalier comes standard with 16-inch rims, and the original tires are commonly Maxxis/Giti/Kumho. New drivers should pay attention to three things: tire age should not exceed 5 years (check the last four digits of DOT), tread depth below 1.6mm must be replaced, and don't use the spare tire as a main tire for long periods. Last time during heavy rain, I personally experienced that aged tires have less than a quarter of the drainage capacity of new tires, and the braking distance increased by over two meters. It's recommended to check for tread cracks every season and stop using the tire immediately if there are sidewall bulges.
