Can I Change the Rims Without Changing the Tires?
2 Answers
Whether to change the tires after replacing the rims depends on the size of the rims. Reasons: The diameter of the rims: Upgrading to larger rims provides better visual appeal and enhances the subjective driving experience. However, larger rims require the use of larger-sized tires. The width of the rims determines the appropriate tire width. For performance-oriented car owners, wider tires can deliver superior performance. Precautions for Rim Replacement: Avoid blindly increasing rim size for aesthetic purposes, as larger rims can significantly impact ride comfort. Rims are generally categorized into forged and cast types, with varying quality levels, so careful selection is necessary.
It is feasible to change the rims without replacing the tires, provided that the tire size matches the new rims. There are several key parameters for rims, such as the diameter which must be the same as the original, the width (often referred to as the J value) should be within the range specified by the tire, and the offset (ET value) must also be correct. Otherwise, the tires may leak air or slip when installed. If the rims are too large, the tires won’t fit tightly, leading to faster air leakage and accelerated wear. An incorrect offset can affect steering control or even cause the tires to rub against the body. I’ve seen many friends recklessly change rims, resulting in unstable tire pressure and unsafe driving. It’s advisable to carefully check the tire wear condition before changing rims—if the wear is minimal, you can save money by keeping the tires, but be sure to have the repair shop verify the specifications and installation to ensure safety. Driving safety is not something to take lightly; spending extra time on measurements is always better than dealing with accidents.
