  • Recognized for producing reliable, high-quality bicycle and wheelchair tires.

  • Offers robust products suitable for various types of usage, including personal mobility and recreation.

Compatibility

1. Wheel Compatibility:

   • Fits rims with ISO 590 mm diameter.

   • Not compatible with Schwinn ISO 597 mm rims (found on vintage Schwinn bicycles like S-5 and S-6).

2. Applications:

   • Bicycles: Designed for vintage bicycles and some modern hybrid or utility bikes that use ISO 590 rims.

   • Wheelchairs: Suitable for many wheelchairs requiring 26 x 1-3/8 tires, provided they are compatible with ISO 590 mm rims.

3. Usage Environment:

   • Paved roads, urban areas, and smooth indoor surfaces (wheelchairs).

   • Light outdoor use on gravel or dry trails.

4. Frame and Clearance Requirements:

   • Ensure adequate clearance within the wheelchair or bicycle frame for the 26 x 1-3/8 size.

Performance Characteristics

• Rolling Efficiency:

  • The semi-slick tread provides excellent efficiency on smooth, flat surfaces, reducing the effort required for mobility or cycling.

• Traction:

  • Offers sufficient grip on dry and slightly uneven terrain, making it ideal for urban and light outdoor use.

• Durability:

  • The wire bead and reinforced rubber compound enhance wear resistance and provide extended service life.

Wheelchair-Specific Notes

• Mobility Features:

  • The smooth rolling properties and high PSI capacity contribute to easy maneuverability for wheelchair users.

  • Lightweight design ensures minimal impact on overall chair performance.

• Comfort:

  • Higher PSI reduces rolling resistance, allowing for smoother movement over various surfaces.

• Safety:

  • Durable sidewalls reduce the risk of punctures, ensuring consistent performance for mobility needs.
