Product.Nr.: 990017090
Manufacturer: Novio
This high-quality inner tube is designed for tyres of size 135/145 R13 and offers a reliable solution for various industrial and garden applications. It is ideal as a replacement tube or for original equipment and ensures safe and stable air pressure in the tyre. Thanks to the matching dimensions and the standardised TR13 valve type, the tube is easy to install and compatible with several common tyre sizes.
Technical data
- Tube size: 135/145 R13
- Inch size: 13 inch
- Also suitable for: 145/155/70 R13
- Valve type: TR13
Valve type TR13 – technical details:
- Valve hole diameter: approx. 15.7 mm (standard for car/universal valves TR13)
- Valve length: approx. 32–38 mm above rim surface
- Design: Straight rubber valve with metal core
- Application: For rims with cylindrical valve hole, typically on narrow car, trailer and implement rims
- Seal: Integrated rubber seal, seals directly in the rim hole
- Fixing: Push-through valve that is fixed without additional nut (press fit in the hole)
Advantages and application
The 135/145 R13 TR13 tube is particularly versatile and suitable for tyres in sizes 135/145 R13 as well as 145/155/70 R13. This makes it ideal for various applications such as light trailers, garden equipment, small commercial vehicles or other machinery with 13-inch tyres.
The standardised TR13 valve type allows easy inflation with conventional air filling devices and ensures reliable sealing in the rim. Due to its design for 13-inch rims, it provides an optimal fit in the tyre, which increases operational safety and reduces the risk of creasing or leaks.
Whether as a replacement for a defective tube or for building new wheels – this tube offers a durable and practical solution for many industrial and horticultural applications.
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.
