It is possible to install wider tires on a motorcycle, including the Royal Enfield Thunderbird 350, but there are a few considerations to keep in mind.
First, check the motorcycle's owner manual or consult with a trusted mechanic to determine the maximum tire size that can be safely fitted on your Thunderbird 350. The manual should provide the recommended tire sizes and specifications for the front and rear tires.
When choosing wider tires, it's essential to ensure they are compatible with the motorcycle's rims and won't interfere with other components, such as the fenders or swingarm. Installing significantly wider tires may require modifications to the motorcycle, such as adjusting the suspension or modifying the fenders.
As for specific tire brands and dimensions, there are various options available, and the choice depends on your preferences and riding style. Popular tire brands for motorcycles include Michelin, Pirelli, Dunlop, Metzeler, and Bridgestone. When selecting tires, consider factors such as the intended use (street, touring, off-road), grip, tread pattern, durability, and overall performance.
To determine the appropriate tire dimensions, you can refer to the motorcycle's manual or seek advice from a reputable tire dealer or mechanic. They will be able to provide you with suitable options based on your desired wider tire size.
It's worth noting that modifying the tires on your motorcycle may affect its handling characteristics, so it's crucial to ensure any changes you make are within safe limits and are done by professionals with expertise in motorcycle modifications.
