Do I need to change tires when modifying wheel size?
2 Answers
Modifying wheel size requires changing tires. Tire replacement timing: It is recommended to replace tires every four years, even if the mileage is relatively low during those four years. Tires are rubber products, and rubber products will age over time with prolonged use. Tire selection: When purchasing tires, be sure to check the specifications and model clearly, as well as the production date, speed rating, and load index. Generally, the sidewalls of tires for family cars or SUVs will have markings like 91V. After reinstalling tires, it's essential to perform wheel balancing to prevent abnormal vibrations during high-speed driving.
As an experienced driver who has been behind the wheel for many years, changing the wheel rim size isn't something you can just do on a whim—it usually requires changing the tires as well. When the size of the rim changes, the old tires often won't fit the new rims properly. Forcing them on can lead to a loose fit, increasing the risk of wheel wobbling or even a blowout while driving. I once upgraded my rims from 16 inches to 18 inches and had to replace the tires because the original ones didn't match the new diameter. This not only affected handling—the steering wheel shook noticeably—but also made the car more likely to be flagged by traffic police for fines. My advice is to visit a repair shop to measure and ensure the new tires' width and height are compatible with the rims. Don't cut corners to save a little money only to risk a major accident. Safe driving should always be the top priority.
