This tube in size 800/45-30.5 is designed for high-volume tyres in industrial, agricultural and municipal applications. It is particularly suitable for wide low-pressure tyres as used on trailers, slurry tankers, earthmoving machinery or large garden and municipal equipment. The robust material and the specially designed TR218A valve ensure reliable sealing and stable air pressure even under high loads.

Technical data

• Tube size: 800/45-30.5
• Inch size: 30.5 inch
• Valve type: TR218A

Valve TR218A – technical details

The TR218A is a widely used valve for high-volume tube-type tyres in agricultural and industrial applications. It is designed for high air volumes and comparatively low to medium operating pressures and allows fast inflation and deflation of the tyre.

Typical features of the TR218A valve:

• Valve hole diameter: approx. 20.5 mm (0.805")
• Valve length (external): approx. 38–45 mm (depending on tube design)
• Design: Straight, large-dimension valve with metal body and replaceable valve core
• Mounting: Secured with locknut from the outside in the rim hole
• Suitable pressure range: designed for low to medium operating pressures in agricultural and industrial use
• Inflation and deflation characteristics: high air flow for rapid filling of large volumes

Benefits and applications

The 800/45-30.5 tube with TR218A valve is ideal for applications where large tyre dimensions and high load capacities are required. These include, among others, agricultural trailers, slurry tankers, earthmoving machines, municipal and special-purpose vehicles as well as large garden and turf-care machinery.

Thanks to the matched combination of large-volume tube size and TR218A valve, this tube offers:

• reliable pressure stability under high loads
• good adaptation to soft ground and uneven terrain
• fast air exchange during inflation and deflation
• high operational safety in continuous professional use

This makes the tube a suitable solution for users who need a robust, easy-to-service and durable tube solution for high-volume tyres in industrial, agricultural and gardening applications.
