Do I Need to Change Tires When Replacing Car Rims?
2 Answers
Whether you need to change tires when replacing car rims depends on the situation: 1. If you replace with rims of the same model, there is no need to change the tires; 2. If you replace with rims of a different model, you need to change the tires to match the new rims. The maintenance methods for rims are: 1. When the vehicle is in a humid area, the rims should be cleaned frequently to prevent salt from corroding the aluminum surface; 2. If necessary, after cleaning, you can wax the rims to maintain their luster; 3. When the rims are at a high temperature, let them cool naturally before cleaning. Do not use cold water to clean them, as it may damage the aluminum rims, deform the brake discs, and affect braking performance. Using detergent to clean the rims may cause chemical reactions on the surface and result in loss of luster.
I've been into car modifications for several years, and changing rims is a common practice. Whether you need to change tires when replacing rims depends on whether the new and old rim sizes are the same. If the rim size remains unchanged—for example, swapping the original 17-inch rims for new 17-inch ones—and the tires are still in good condition, there's no need to replace them, saving you money. However, if you're upgrading the size, such as from 16-inch to 18-inch rims, you must get new tires to match. Otherwise, the tires won't fit properly, or the car may shake severely at high speeds, increasing the risk of losing control. I've seen a friend who only changed the rims without replacing the tires, leading to a serious mismatch that significantly raised the risk of a blowout at high speeds. So, before every rim change, I always measure the bolt pattern and width carefully and consult a professional shop for evaluation. Tire lifespan is also crucial—if the tread is worn down to the wear indicator, it's better to replace them together for safer driving. Never skimp on matching issues to save money, as it could cost you more in the long run.
