Can a car with 16-inch rims be fitted with 17-inch rims?
2 Answers
A car with 16-inch rims cannot be fitted with 17-inch rims. According to relevant regulations, vehicles are not allowed to be modified with rims that do not conform to the original model's specifications. The technical parameters of the new and old rims should remain consistent; otherwise, corresponding penalties may be imposed. The rim is the rotating part of the wheel that connects the tire's inner contour to the hub via spokes, which is the metal component mounted on the axle that supports the tire. Rims are also called wheel rims. Depending on the characteristics and requirements of different vehicle models, the surface treatment processes for rims may vary, generally categorized into painting and plating. For ordinary vehicles, rims are less considered for appearance, with good heat dissipation being a basic requirement. The process typically involves painting, i.e., spraying followed by baking, which is economical, offers vibrant colors, and ensures long-lasting durability.
Actually, I upgraded my previous car from 16-inch to 17-inch wheels, and they did fit. When swapping, you need to pay attention to lowering the tire's aspect ratio so that the overall wheel diameter stays close to the factory specs—otherwise, the speedometer will be inaccurate. The braking system also needs to be checked, as larger wheels might require bigger brake discs to function properly. The wheel's bolt pattern and center bore dimensions must match the original car's specs, or installation will be problematic. After the upgrade, the car felt more stable to drive, with noticeably better grip during cornering, though it became noticeably bumpier over speed bumps. It's best to check local regulations first, as some places have restrictions on modifications to avoid issues during annual inspections.
