1. Introduction
Thank you for choosing the KENDA K191 700C Road Bicycle Tire. This manual provides essential information for the safe and effective use, installation, and maintenance of your new tire. Please read it thoroughly before installation and keep it for future reference.
2. Safety & Warnings
- Tire Pressure: Always check tire pressure before each ride. Incorrect pressure can lead to poor handling, increased risk of punctures, or tire failure. Refer to the specifications section for recommended pressure ranges.
- Inspection: Regularly inspect your tires for cuts, cracks, bulges, or embedded debris. Replace worn or damaged tires immediately. Never use damaged cycling equipment.
- Compatibility: Ensure the tire size (e.g., 700C) and width (e.g., 23C, 25C) are compatible with your bicycle's rims and frame clearance.
- Brakes: Always check your bicycle's brakes before each ride to ensure they are functioning correctly.
3. Setup and Installation
Proper tire selection and installation are crucial for safety and performance. If you are unsure about installation, please consult a professional bicycle mechanic.
3.1 Choosing the Correct Tire
Your KENDA K191 tire is available in various widths for 700C rims. Ensure you select the correct size for your riding style and rim width.
This diagram illustrates the importance of matching the tire's model number (size) to your rim and selecting a tread pattern suitable for your intended use (off-road, urban, racing, wear-resistant).
3.2 Installation Steps (General Guide)
- Remove Old Tire: Deflate the old tire completely, use tire levers to unseat one bead from the rim, then remove the inner tube and the tire.
- Inspect Rim: Check the rim strip for proper placement and condition. Ensure the rim is clean and free of sharp edges.
- Mount First Bead: Place one bead of the new KENDA K191 tire onto the rim.
- Install Inner Tube: Lightly inflate the inner tube (just enough to give it shape) and insert it into the tire, ensuring the valve stem passes through the rim's valve hole.
- Mount Second Bead: Starting opposite the valve, work the second bead of the tire onto the rim. Use your thumbs or tire levers carefully to avoid pinching the inner tube.
- Seat Tire: Before fully inflating, push the valve stem up into the tire to ensure the tube base is not trapped under the tire bead. Work your way around the tire, pushing the beads towards the center of the rim to ensure they are evenly seated.
- Inflate: Inflate the tire slowly, checking that the beads seat evenly on both sides of the rim. Inflate to the recommended pressure (see Specifications).
4. Operating Guidelines
4.1 Tire Pressure
Maintaining correct tire pressure is vital for performance, comfort, and puncture resistance. Refer to the table below for recommended pressure ranges for different tire sizes. Always check the sidewall of your specific tire for exact pressure limits.
This image details the tire's high-quality material, TPI braid inside, and provides a table for recommended tire pressures based on tire size (e.g., 700*25C at 770KPA, 700*28C/35C/38C at 350-600KPA).
4.2 Performance Features
- Optimized Tread Profile: The KENDA K191 features an optimized tread profile designed to moderate road shock and suppress vibrations, providing a smoother ride.

5. Maintenance
- Regular Cleaning: After riding, especially in wet or dirty conditions, clean your tires to remove mud, grit, and debris. This prevents premature wear and helps identify potential damage.
- Storage: Store your bicycle in a dry place, away from direct sunlight and extreme temperatures, which can degrade rubber over time.
- Pressure Checks: Regularly check and maintain the recommended tire pressure, even when the bicycle is not in use for extended periods.
- Wear Inspection: Periodically inspect the tire tread and sidewalls for signs of wear, cuts, cracks, or embedded sharp objects. Replace tires when the tread is worn down or if significant damage is present.
6. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Frequent flat tires | Underinflation, sharp objects embedded in tire, damaged rim strip, pinched inner tube | Maintain correct pressure, inspect tire for debris, check rim strip, ensure tube is not pinched during installation. |
| Tire not seating evenly on rim | Beads not fully engaged, tube trapped under bead | Deflate slightly, push beads towards rim center, ensure tube is clear, reinflate slowly while checking seating. |
| Tire wobbles or feels unstable | Improper installation, damaged tire, bent rim | Re-install tire carefully, inspect tire for defects, check rim for true. Consult a mechanic if issues persist. |
| Poor grip in wet conditions | Worn tread, incorrect tire pressure | Replace worn tires, ensure correct tire pressure. |
