IRC Motorcycle Tire Inner Tube 4.00/5.10-17 TR4 Valve — Japanese-made butyl blend, standard duty

The IRC Standard Duty inner tube T20052 is a Japanese-made replacement tube for 17" motorcycle wheels, offered in sizes 4.00/5.10-17, 4.60/5.10-17 and 110/100-17 with a TR4 valve stem.

This inner tube combines natural rubber with butyl to deliver a balance of elasticity and air retention typical of higher-grade OEM parts. Manufactured in Japan to meet or exceed factory quality benchmarks, the T20052 is designed for everyday riding where reliability, puncture resistance and consistent inflation are important. It’s a straightforward replacement tube compatible with many street and light off-road motorcycles that use 17-inch rims and require a TR4 (commonly called TR4A/TR4B) valve stem.

Which tire sizes will this IRC tube fit?

The T20052 covers several common 17" tire widths, removing guesswork when replacing a worn tube. Choose the exact size listed on your tire sidewall to ensure proper seating and even inflation.

• Fits 4.00-17 and 5.10-17 tire profiles
• Fits 4.60-17 and 5.10-17 tire profiles
• Fits 110/100-17 metric size commonly used on rear or front wheels

How durable and puncture resistant is the tube?

IRC constructs this tube from a blend of natural rubber and butyl to combine flexibility with superior air-holding qualities. The compound and manufacturing standards give it improved puncture resistance over cheap, thin tubes, making it suitable for regular riding conditions.

• Thicker rubber body for increased resistance to pinches and small punctures
• Butyl content improves long-term air retention versus natural rubber alone
• Made to meet or exceed OEM quality standards for consistent performance

Which valve stem does the T20052 use and why it matters?

The tube is supplied with a TR4 valve stem, a common straight valve that fits standard rim valve holes. Using the correct valve type ensures a secure fit, prevents leaks at the stem base, and allows compatibility with widely available caps and pump adapters.

• TR4 valve stem is standard for many motorcycle rims and accessible pumps
• Firm valve seating reduces the risk of air loss at the rim interface
• Compatible with common tire pressure monitoring and inflator tools

What materials and manufacturing standards are used?

IRC uses a rubber blend—incorporating both natural rubber and butyl—to balance elasticity and airtightness. The tube is produced under Japanese manufacturing practices aimed at meeting or exceeding OEM requirements so riders get dependable inflation stability and consistent wall thickness.

• Blend of natural and butyl rubber for strength and air retention
• Manufactured to Japanese quality standards and OEM-equivalent tolerances
• Designed for standard road and light off-road usage

Who is this for: The IRC T20052 inner tube is intended for riders and mechanics who need a trustworthy, OEM-quality replacement for 17" motorcycle wheels that call for 4.00/5.10-17, 4.60/5.10-17 or 110/100-17 sizes with a TR4 valve. It’s suitable for commuter bikes, standard street motorcycles and light dual-purpose use where a balance of puncture resistance and reliable air retention matters.
