Can the original 17-inch wheels be upgraded to 18-inch wheels?
2 Answers
Yes, but you need to pay attention to the following when modifying: Proper matching: If you upgrade the original wheels to a larger size, you must ensure proper matching. If not done correctly, the vehicle's height may visually appear increased, which can look very unnatural and even negatively affect daily driving. Wheel weight: Regardless of the material, larger wheels are heavier. Due to their increased weight and longer circumference, they require more power to rotate. However, a car's power configuration is set at the factory, so upgrading to larger wheels may result in slower acceleration and longer response times. Additionally, heavier wheels increase the load on the braking system, leading to longer braking distances. This is particularly important when driving at high speeds, as emergency braking requires precise control of stopping distance. This consideration is crucial for personal safety.
I usually enjoy tinkering with car modifications. Upgrading from the stock 17-inch wheels to 18-inch ones is completely feasible, but the key is to pair them with appropriate tire sizes to ensure the overall diameter remains close to the factory standard. Otherwise, the speedometer and range calculations will be inaccurate, and it may also affect the functionality of the ABS and ESP systems. 18-inch wheels enhance handling precision and improve stability during turns, but the ride becomes noticeably stiffer, leading to more bumps over speed bumps or rough roads, which reduces comfort. Fuel consumption may increase slightly by around 5%, so long-term driving costs should be considered. Additionally, the suspension system may bear extra stress, and tire wear could accelerate. Before modifying, confirm that the wheel’s ET value matches the brake components to avoid scraping the body or calipers. It’s highly recommended to consult a professional repair shop for evaluation and installation to ensure legality and compliance—DIY attempts might lead to failed inspections and bigger headaches.
