Choosing the Right Tire Brands

Tire Brands to Consider:

Michelin: Known for their performance and durability. Pirelli: Offers a range of tires with good grip and handling. CEAT: Provides good quality tires at a reasonable price. MRF: Popular in India, known for their reliability and performance.

Before purchasing any tires, ensure that they fit within the wheel wells properly and do not rub against the frame or suspension parts. Wider tires can affect the motorcycle's handling characteristics, especially in corners, so it's essential to be aware of these changes.

Installation Considerations

The stock swing arm on the Thunderbird 350 supports tire sizes up to 120/80-18. If you want to install wider tires, you may need to modify the swing arm. Alternatively, you can purchase a swing arm designed for wider tires. These modifications can often be costly and require professional assistance to ensure safety and proper fitment.

For example, installing a 150mm fat tire requires a swing arm that can support this size. The swing arm usually costs around 2000 INR. Without a suitable swing arm, it would be very difficult to install such tires.

Personal Experiences and Tips

Based on real experiences, installing wider tires can indeed enhance the Thunderbird 350's performance:

"One of my friends installed wider tires on his Thunderbird, which resulted in better grip and cornering. The transition was smooth, but he noted that cornering stability was a bit different."

Another rider mentioned:

"The MRF Zapper tire worked great, providing excellent grip, while some others suggested the EuroGrip for long-lasting performance and top-notch safety."

MRF Zapper is a reliable choice, and EuroGrip is highly recommended for its consistent performance over time. Both brands offer optimal grip and longevity, making them suitable for everyday riding.

Care and Maintenance

After installing wider tires, it’s essential to maintain them properly to ensure they last as long as possible. Regularly check for wear, maintain proper tire pressure, and address any issues promptly.

Here are some tips for optimal tire care:

Check the tire pressure regularly and inflate according to the manufacturer's guidelines. Rotate the tires periodically to ensure even wear. Inspect the tires for any cuts or damages during routine checks. Store the motorcycle properly to prevent damage to the tires.
