Manufacturer: KINGS TIRE
This 2.50-6 tube from KINGS TIRE is designed for small wheels in industrial, transport and garden applications and provides a reliable, airtight air supply. It is ideal for wheelbarrows, small trailers, garden and municipal equipment as well as various machines with 6-inch tyres. Thanks to the robust rubber material and the angled JS87 valve, the tube is particularly easy to mount and designed for daily use.

Valve type JS87 – properties
The JS87 valve is an angled tube valve specifically developed for smaller wheels and allows convenient inflation even where space is limited.
Typical characteristics of a JS87 valve:
- Design: angled valve (usually 90° angle) for better accessibility
- Valve hole drilling: designed for standard rim bed holes of approx. 8–11 mm (depending on rim design)
- Valve length: compact design, low overall height to minimise damage
- Valve body: metal valve with rubber base for a secure fit in the valve hole
- Valve core: standard car valve core (similar to Schrader principle) for easy inflation and pressure checking
- Seal: integrated rubber seal at the valve base for reliable sealing against the rim
Benefits and application range
The 2.50-6 JS87 tube from KINGS TIRE is a reliable solution for applications where robustness and easy handling are required. The angled JS87 valve makes inflation easier, even when the valve is difficult to access, for example with deep rims or built-in wheels.
Typical applications include:
- Wheelbarrows and hand carts
- Garden and landscaping equipment (e.g. lawn mowers, garden carts)
- Small transport trolleys and sack trucks
- Light industrial and workshop trolleys
The tube is ideal for replacing worn or leaking tubes and extending the service life of existing tyres. With the matching size 2.50-6 and the 6 inch inch size, it is optimally matched to the corresponding tyre and rim combinations and ensures safe, stable running.
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.
