Size: 27 x 1 1/4 inches
ISO 630 mm bead seat diameter (BSD)
This tire fits standard 27-inch rims typically found on older road bikes and touring bicycles.
Specifically designed to fit Schwinn S5/S6 rims, which are slightly wider than typical 630 rims—this tire has a profile and volume that complements those rims for a better fit and ride.
The steel wire bead ensures a firm and secure fit to the rim, providing durability and resistance to blow-offs at high pressure.
Wire bead tires are generally heavier than folding (Kevlar) bead options but are more budget-friendly and durable.
The HF-112 tread is a smooth central slick with subtle side grooves for controlled water displacement.
Designed to provide low rolling resistance and efficient energy transfer, perfect for pavement and dry roads.
Slight grooves improve traction in light rain and help channel water away from the centerline.
Recommended Pressure: 75 PSI
High-pressure design improves rolling speed and reduces rolling resistance.
At this pressure, the tire maintains a firm profile for better handling on paved roads.
Material: Durable rubber compound optimized for long wear and resistance to urban debris.
Side Wall: Gum sidewall offers extra protection and a clean, modern aesthetic.
Use Case: Built for longevity, this tire is designed to handle daily commuting, light touring, and recreational road cycling.
Perfect for city riders needing a fast-rolling, puncture-resistant, and cost-effective tire.
Handles potholes, sidewalk transitions, and paved roads efficiently.
A direct replacement for vintage 10-speeds and touring bikes from the 1960s–1980s.
Especially suitable for Schwinn Varsity, Continental, Traveler, and World Tourist models using S5/S6 rims.
Ideal for long road rides, rail trails, and fitness cycling on asphalt or hard-packed paths.
