- Altered speedometer readings: The speedometer in your vehicle is calibrated to the original tire size, so installing tires with a different aspect ratio may cause it to give incorrect readings. This could be a safety hazard, as you may be driving faster or slower than you think you are.
- Reduced ground clearance: Tires with a taller aspect ratio will increase the overall height of your vehicle, which could reduce ground clearance and make it more likely to bottom out on bumps or obstacles. This can be especially problematic on vehicles with low ride heights.
- Changes in handling: The handling of your vehicle may be affected by changing the aspect ratio of the tires. Tires with a taller aspect ratio may have a softer ride, but they may also be more prone to sidewall flex and less responsive to steering input.
- Potential warranty issues: Changing the tire size from the original specifications may void the warranty on your tires or other components of your vehicle.
For these reasons, it is generally not recommended to replace tires with a significantly different aspect ratio than the original size specified by the vehicle manufacturer. If you have any doubts or concerns about changing tire sizes, it is best to consult with a professional mechanic or tire dealer.
