Introduction
When you own a classic bike like the 1977 Honda 750 CNK, maintaining its performance and aesthetics is critical to ensuring a smooth and enjoyable ride. One common question among owners is finding the largest tires that will fit on 77′ Honda 750 CNK without sacrificing safety, comfort, or performance. This guide will help you understand the best tire sizes, how they affect your ride, and tips on maintaining your bike’s performance.
Understanding Tire Size for the 77′ Honda 750 CNK
When choosing tires for your bike, knowing how tire sizes are measured and how they affect performance is essential. Tire size is typically represented as a series of numbers, such as “110/90-19.” These numbers indicate the tire width, aspect ratio, and wheel diameter. With these factors in mind, the largest tires that will fit on 77′ Honda 750 CNK should be chosen, ensuring the tires fit correctly on the rims and don’t cause issues with the frame or suspension.
- Width: The tyre’s width, measured in millimetres, affects stability and grip. Wider tyres provide more surface area, improving grip on the road, but may only sometimes be the best option for all bikes.
- Aspect Ratio: This represents the height of the tyre’s sidewall as a percentage of its width. A lower ratio means a shorter sidewall and more precise handling, while a higher ratio provides more cushioning.
- Wheel Diameter: This is the wheel size the tyre fits onto, and the tyre must match your wheel’s diameter exactly.

How to Choose the Right Tires
When selecting the largest tires that will fit on 77′ Honda 750 CNK, it’s essential to consider more than just size. You’ll also want to think about:
- Tread Pattern: The tread pattern affects how the bike handles in different conditions. For daily riding, you’ll want tyres with good all-around performance.
- Tyre Compound: Softer compounds offer better grip but wear out faster, while more complex compounds last longer but might not grip as well.
- Tube or Tubeless: The 1977 Honda 750 CNK originally came with tube tyres. If you’re upgrading your wheels, you might want to consider converting to tubeless tires, which are less prone to punctures.

- Adjust Suspension: If upgrading to larger tires, you might need to adjust your suspension settings to accommodate the new size. This guarantees the pleasure and safety of your ride.
- Proper Inflation: Larger tyres require the correct tyre pressure for optimal performance. Ensure you inflate the tires to the recommended PSI to avoid uneven wear or a rough ride.
