Question

I am planning to replace my Pulsar 220F rear Tyre from stock 120/80/17 to 140/70/17, does it suits and won't be any decrease in performance or mileage?

Answer 1

Changing the rear tire size of your motorcycle can have an impact on its performance and mileage. When considering such modifications, it's important to keep a few factors in mind:

1. Compatibility: Before changing the tire size, ensure that the new size is compatible with your motorcycle model. Check the owner's manual or consult with a trusted mechanic to verify if the new tire size is suitable for your Pulsar 220F.

2. Performance: Increasing the width of the rear tire from 120/80/17 to 140/70/17 will generally provide a wider contact patch with the road. This can potentially improve stability and traction, especially during cornering. However, it might also slightly affect the agility and handling characteristics of the bike. The impact on performance can vary based on individual preferences and riding style.

3. Mileage: Increasing the width of the tire may lead to a slight decrease in fuel efficiency. A wider tire creates more rolling resistance, which could result in a small reduction in mileage compared to the stock tire size. The impact on mileage is usually marginal, and it might not be noticeable in everyday riding conditions.

4. Speedometer Accuracy: Changing the tire size can affect the accuracy of the speedometer reading. When the rear tire size increases, the speedometer may display a slightly lower speed than the actual speed. It's worth considering this aspect and recalibrating the speedometer if necessary.

5. Suspension Setup: A wider rear tire can potentially affect the suspension setup. It may require adjustments to maintain the desired balance and ride quality. Consulting with a knowledgeable mechanic or suspension specialist can help ensure that the suspension is properly tuned for the new tire size.

It's crucial to understand that any modifications to your motorcycle, including changing tire sizes, may have consequences on its performance, handling, and mileage. It's recommended to consult with experts, such as authorized service centers or experienced mechanics, who can provide specific guidance based on your motorcycle model and riding requirements.
