Tube 16.9/14-30 TR218A
Product.Nr.: 990017141
Manufacturer: Novio
This tube 16.9/14-30 with valve type TR218A is designed for use in agricultural and industrial applications. It is ideal for tractors, work machines and equipment in gardening and municipal services where a robust and reliable tube for 30-inch tyres is required. Thanks to its matched dimensions, it fits several common tyre sizes and ensures a secure fit as well as reliable air tightness.
Technical data
- Tube size: 16.9/14-30
- Inch size: 30 inch
- Also suitable for: 420/85-30, 480/70-30, 540/65-30
- Valve type: TR218A
Valve-specific data TR218A
- Valve type: TR218A (straight version, high-volume valve for agricultural and industrial tyres)
- Typical valve hole drilling: approx. 16 mm (for large-diameter rim valve holes)
- Valve length: approx. 38–45 mm above rim surface (depending on rim design)
- Design: Straight metal valve with replaceable valve core
- Valve base: Rubber-based valve base, vulcanised firmly into the tube
- Operating pressure range: Designed for the operating pressures commonly used in agriculture and industry (low to medium pressure range)
- Inflation/deflation: Large valve cross-section profile for fast inflation and deflation of large volumes
Benefits and application range
This tube is specially designed for high-volume tyres in the 30-inch segment and, with its 16.9/14-30 size and the compatible dimensions 420/85-30, 480/70-30 and 540/65-30, covers a wide range of applications. It is therefore particularly suitable for tractors, implements, agricultural trailers and various industrial machines.
The TR218A valve type is designed to meet the demands of heavy-duty working conditions. The straight metal valve with large cross-section enables quick inflation and deflation, which saves time especially with high-volume tyres. The robust design ensures high stability in daily use, even with frequent pressure adjustments.
Overall, this tube offers a reliable solution for users who value compatibility with multiple tyre sizes, robust valve technology and safe operation in agricultural and industrial environments.
Frequently asked questions about this product
The valve designation describes two things: the stem diameter — which must fit the hole in the rim — and the shape, i.e. straight or angled.
Only the bore matters for a proper fit: a valve fits perfectly only if its stem matches the bore in the rim. Whether it is straight or angled makes no difference — that is a question of accessibility.
An overview of the types:
| Type | Shape | Bore | typically used for |
|---|---|---|---|
| TR13 | straight, rubber | 11.5 mm | Car and trailer wheels |
| TR4 / TR6 | straight, short | 11.5 mm | Small wheels, garden tools |
| TR15 | straight, rubber | 16 mm | Agricultural machinery, tractor rims |
| TR87 | 90° angled | 11.5 mm | Small wheels, solid rims |
| JS8 (DIN 7777) | 90° angled, same as TR87 | 11.5 mm | small wheels, solid rims |
| JS2 | Approx. 70° angled | 11.5 mm | Industrial and small wheels |
| V3-02-7 (TR75) | 100° single-bend metal angle valve with screw-on base | 12.2 mm | Commercial vehicles, lorries, trailers, agricultural and industrial machinery such as forklift trucks |
| V3-06-3 | Triple-bend brass truck screw-on valve (90°/139°/139°) | 9.7 mm | 20-inch truck and trailer tubes (6.00-20 to 9.00-20), also 22.5-inch tube-type tyres |
| TR218A | Straight metal air-water valve, two-piece | 15.9–16 mm | High-volume tubular tyres for agricultural and industrial use, tractors |
V3-02-7 in detail: Also known as ETRTO V3.02.7 and US designation TR75. Dimensions: Horizontal leg length 22.5 mm, vertical leg length 71.5 mm, total height approx. 91 mm. The valve base is screwed on, not pressed in — this makes it significantly more robust than a rubber valve.
V3-06-3 in detail: Also known as ETRTO V3.06.3. Triple-bend brass screw-on truck valve: the first bend is 90°, the other two 139° each — this guides the filling end past the rim flange and keeps it accessible even with twin tyres and deep rim wells. Leg dimensions approx. 20.5 / 46 / 20.5 / 47.5 mm (approx. 135 mm developed length), rim hole 9.7 mm. The valve is fastened to the tube with a sealing washer and nut instead of being vulcanised in. In our range on the 20-inch tubes 6.00/6.50-20, 7.00/7.50-20, 8.25-20 and 9.00-20.
TR218A in detail — the valve for water ballast: What makes this type special is the option for liquid ballasting: the hose is partially filled with water to increase the vehicle’s weight and thus improve traction — a common practice with tractors.
- Design: straight, robust metal valve, usually in two parts. Unscrewing the inner CH3 valve insert creates an extra-large opening — allowing for quick filling with air or liquid.
- Rim bore: 15.9 to 16 mm (0.625 inches).
- Length: typically around 38 to 48 mm total height above the rim.
- Mounting: a rubber base approximately 80 mm in diameter for vulcanising onto the inner tube, plus a lock nut for secure attachment to the rim.
Reducing sleeves: A TR15 valve does not fit into an 11.5 mm bore. Conversely, there are sleeves that allow a TR13 valve to fit into a 16 mm bore.
Whether straight or angled is not a question of fit, but of accessibility: with closed rims or small wheels, it is often impossible to reach the valve with a pump using a straight valve — in which case an angled one is used.
Not sure which valve is fitted? A photo of the old valve is all we need to identify it. Choose from: inner tubes, bead tapes and valves.
