Here's why it's not recommended:
1. Tire Deformation: The 175/65 R15 tire is narrower than the 195/55 rim, which can cause excessive tire deformation when mounted. This deformation can compromise the tire's performance and stability.
2. Reduced Load Capacity: The 175/65 R15 tire has a lower load rating compared to the 195/55 tire, which means it is not designed to carry the same amount of weight as the original tire. This can be dangerous, especially for heavy vehicles or when driving at higher speeds.
3. Altered Handling and Performance: The difference in tire width and aspect ratio will affect the vehicle's handling characteristics. The narrower tire may result in reduced grip and traction, making the vehicle less responsive and potentially more difficult to control.
4. Speedometer and Odometer Discrepancies: The 195/65 R15 tire has a different rolling circumference than the 175/65 R15 tire. This can cause inaccuracies in the vehicle's speedometer and odometer readings, affecting fuel economy calculations and legal compliance.
For safety and optimal performance, it's crucial to use tires that are specifically designed and approved for your vehicle's wheels and load requirements. Consult your vehicle's owner's manual or a reputable tire dealer to determine the correct tire size and specification for your car.
