Yes, it is possible to replace a 90/90-18 tire with a 110/90-18 tire, but there are a few factors to consider:
Fitment: The first thing to ensure is that the larger tire size will fit within the available space on your motorcycle. Check the clearance between the tire and other components such as the swingarm, fender, and frame to ensure there is enough room for the larger tire size. Additionally, confirm that the wider tire will clear any braking or suspension components without interference.
Handling and Performance: Installing a wider tire can impact the handling and performance characteristics of your motorcycle. A wider tire may provide increased stability and grip, especially during cornering, but it can also affect the bike's responsiveness and overall handling characteristics. It's recommended to consult the manufacturer's specifications or seek advice from a reputable motorcycle mechanic or tire specialist to ensure that the larger tire size is suitable for your specific motorcycle model.
Speedometer and Odometer Accuracy: Changing the tire size can affect the accuracy of your motorcycle's speedometer and odometer readings. A larger tire circumference can result in an overestimation of your speed and a lower mileage reading. This is because the speedometer and odometer are calibrated based on the original tire size. If you switch to a larger tire, you may need to recalibrate or adjust the speedometer and odometer to ensure accurate readings.
Insurance and Legal Considerations: Depending on your jurisdiction, modifications to the tire size may have legal implications or affect your motorcycle's insurance coverage. It's important to check local laws and regulations to ensure compliance and verify with your insurance provider if any changes in tire size will impact your coverage.
It's advisable to consult with a knowledgeable motorcycle mechanic or tire specialist who can assess your specific motorcycle model and provide guidance on the suitability and implications of changing the tire size. They can take into account factors such as your riding style, intended usage, and any potential modifications required to accommodate the larger tire size.
