1. Wheel Size Compatibility: R15 and R16 refer to the wheel diameters. Replacing R15 tires with R16 tires means installing larger diameter tires on the same wheels. This can lead to clearance issues with brake components and suspension components.
2. Wheel Well Clearance: The larger diameter tires may rub against the inner fender liners or other parts of the wheel well, causing damage or affecting the vehicle's handling and stability.
3. Speedometer Calibration: The speedometer of your car relies on the tire diameter to calculate the vehicle's speed. Changing the tire diameter may affect the accuracy of the speedometer and odometer.
4. Ride Quality: Larger diameter tires tend to have lower sidewalls, which may result in a compromised ride quality. The larger wheels and lower-profile tires may provide less cushioning and result in a stiffer and bumpier ride.
5. Fuel Efficiency: Changing the tire size can affect the vehicle's fuel efficiency. Larger diameter tires may increase the rolling resistance, leading to reduced fuel efficiency.
6. Legal and Safety Considerations: In some countries and regions, it is illegal to operate vehicles with tires of different sizes. It is important to check the local regulations regarding modifications and tire changes.
If you still want to replace R15 tires with R16 tires, it's crucial to consult with an experienced automotive technician or a reputable tire shop. They can assess your vehicle and provide guidance on whether the change can be done safely and properly. Keep in mind that such modifications may require adjustments to suspension components, wheel size, and potential modifications to the wheel wells to ensure proper clearance.
