Refine S3 is a compact SUV under Motors, with 19 models currently on sale, all equipped with 201/55-R16 wheel specifications. Below is relevant information about car tires: 1. Functions of tires: Support the entire weight of the vehicle, bear the load of the car, and transmit forces and moments in other directions; transmit traction and braking torque to ensure good adhesion between the wheels and the road surface, improving the car's power, braking, and passability; work with the car suspension to mitigate impacts during driving. 2. Tire lifespan: The lifespan of tires is related to many factors, such as climate, road conditions, driving habits, installation, maintenance, etc. According to international regulations, if the tires are used normally, they must be replaced when the tread depth wears down to 1.6 mm.

I just got my hands on a Refine S3 and have specifically researched its tire specifications. The base model comes with 205/55 R16 tires, and the 16-inch rims are quite common. If you opt for the higher trim, it upgrades to larger 205/50 R17 rims. In actual driving, the 55 aspect ratio tires provide a more comfortable ride over speed bumps and generate less road noise. A word of caution: don’t randomly change the tire size when replacing them. My neighbor once switched to wider 215 tires and ended up scraping the wheel arches during turns. The tire specifications are directly marked by a series of numbers on the sidewall, so remember to check the tread depth during maintenance. The factory-fitted tires for this car are generally durable all-season tires.

I've seen quite a few Refine S3 models in repair shops, with tires coming in two specifications. Most vehicles come standard with 205/55R16 tires, while the premium version uses 205/50R17. Be careful not to buy the wrong size when replacing tires, especially since there's a 5% difference in the aspect ratio between 50 and 55. Just the other day, an owner bought mismatched tires to save money, resulting in a speedometer error exceeding 5 km/h. It's recommended to stick with the factory specifications, as the tire pressure monitoring system is designed for specific sizes. Regular checks should focus on three key indicators: 205mm width, 55% aspect ratio, and 16-inch wheel diameter.

Essential Tire Knowledge for Refine S3 Owners: The standard tire size is 205/55R16, where 205 indicates the tire width. When selecting tires, pay attention to the load index and speed rating - the factory original usually carries a 91V marking. I've seen some owners upgrade to 17-inch rims, but this requires corresponding suspension adjustments. Tire pressure is crucial; maintain 2.3-2.5 bar during winter. Remember to use identical tread patterns when replacing tires on the same axle, as this directly affects ESP performance. It's recommended to perform wheel alignment every 20,000 km to effectively prevent uneven wear.

Three years of experience with Refine S3: The original 205/55R16 tires balance comfort and fuel efficiency. When I tried switching to 215-width tires, fuel consumption immediately increased by 0.5L. The last number 16 in the tire specification represents the rim diameter. For winter tires, it's more cost-effective to choose a smaller 15-inch size. Remember to check the tire manufacturing date during each maintenance service. Tires older than six years should be replaced even if the tread is deep. Once on the highway, I noticed steering wheel vibration, which turned out to be lost wheel balance weights on the front tires. Now I always keep a portable air pump handy to address abnormal tire pressure promptly.

Compared the tire differences between the high and low configurations of the Refine S3: The low configuration's 205/55R16 is more economical, while the high configuration's 205/50R17 offers slightly better handling. New tires are marked with DOT codes, with the last four digits indicating the production week. Last time I changed tires, I noticed many stones stuck in the drainage grooves, and the mechanic said it was due to excessive tire pressure. For daily use, do not exceed the tire's maximum speed rating; the V-rated tires on this car with a top speed of 240 km/h are sufficient. When repairing tires, prioritize the mushroom plug method, as it is much more durable than patches. Additionally, even though the spare tire is a temporary T-type, its air pressure should be checked regularly.
