Dunlop K70 Universal Motorcycle Tire 3.50–19 Tube Type
The Dunlop K70 is a modern reproduction of a vintage tire designed for tube-type setups in 3.50–19. It is best for classic restorations that aim to maintain period-correct appearance while relying on contemporary manufacturing standards. This option is especially suitable for riders who want authenticity in the tire’s look and footprint without sacrificing basic reliability. Best for restoration-focused riders. Data and installation should be verified by a tire professional and the owner’s manual before use. A potential limitation is its vintage-tet of design; verify compatibility with your exact model year and frame clearance.
Relibupdater 3.75-19 Inner Tube
Relibupdater’s 3.75-19 inner tube is described as heavy duty, with a focus on easy installation and stable ride quality. It is designed to fit a range of bikes that use 3.50–4.00-19 tubes, including several R71/M72-OS models. It’s a good pick for riders seeking a straightforward swap with robust air retention. Better for simple, quick installs. Caution: confirm the exact valve type and fitment for your wheel/tork setup and ensure the tube’s size compatibility with your rim bed.
RUTU 3.75-19 Inner Tube
RUTU’s inner tube is marketed for wide compatibility, including 3.50-19 and related sizes. The design emphasizes durability, air retention, and a TR4 straight valve with sturdy valve seats, making it a strong choice for riders who want reliable, leak-resistant performance across multiple bikes. Choose this if you need broad compatibility. A note: while the tube is described as durable, user fit and mounting can vary; follow installation guidance carefully to prevent leaks.

The Shinko SR241 is a tube-type, bias-ply trials tire suitable for Husqvarna TC 125 models in the listed generation. Its DOT compliance and bias-ply construction reflect a vintage-trials bias, favoring steady grip in mixed-terrain scenarios. Best for trials or light off-road use. Limitation: not all 3.50-19 street bikes will accept this tire; ensure rim compatibility and intended use align with trials applications.
Shinko SR241 Series 3.50×19 Tube Type (Husqvarna TC 250 2004-2013)
This Shinko SR241 listing also covers Husqvarna TC 250 models from 2004–2013, indicating the tire’s suitability for bikes used in mixed conditions and trials-style riding.

The Kenda tube pack provides premium butyl rubber with a straight TR-6 valve stem in a 3-pack. This is well-suited for riders who want multiple spare tubes with consistent quality for standard 3.50-19 applications. Best for cost-effective spares. Limitation: tubes in packs may include minor variations; verify valve type and correct sizing for your wheel before install.
Buying Guide
What should you check before buying 3.50 x 19 tyres or inner tubes?
- Rim compatibility: Confirm your rim width and bead seatDiameter aligns with the tire size and tube type.
- Tire vs. tube: If you already have a tubeless wheel, ensure you’re selecting a tube-type tire or tube accordingly.
- Riding style: Vintage restorations may prioritize authentic tread patterns; trials or dual-sport use may prioritize grip and durability in mixed terrain.
- Valve type and length: Ensure the valve fits your rim hole and your tire pump or gauge access is convenient.
- Durability and climate: Consider heavy-duty tubes for rough roads or hot climates where air retention matters more.
- Installation ease: Some tubes advertise easy fit; follow manufacturer guidelines to avoid pinch flats.
What is the difference between a tube-type tire and a tube?
A tube-type tire requires an inner tube to hold air, while a tubeless tire does not. Tube-type tires are common on older motorcycles and some classic restorations, offering easier mounting on certain rims but requiring careful installation to prevent leaks.
Which product is best for a restoration project?
The Dunlop K70 stands out for restoration-focused riders due to its vintage look while providing modern manufacturing standards. It aligns with classic bikes that demand period-accurate aesthetics without sacrificing basic reliability.
Are inner tubes compatible across different brands?
Inner tubes with similar sizing (like 3.75-19 or 3.50-19) can fit across multiple brands, but always verify the exact tire fitment, valve type, and rim compatibility for your specific bike model.
How many spare tubes should a rider keep?
Having two or three spare tubes is practical for riders who regularly travel long distances or ride on rough terrain. This minimizes downtime in case of a puncture and can be essential for older bikes with limited service options nearby.
What are common installation cautions?
Avoid pinching the tube between tire bead and rim, examine the tube for puncture risks during mounting, and use appropriate lubricants or soapy water to ease bead seating. Always inflate gradually and check for leaks after installation.
