OXFORD PSI Alert 28 (1.9-2.07 bar)

OXFORD PSI Alert – The smart valve caps for instant pressure warning

The OXFORD PSI Alert valve caps are the simple and effective solution for keeping an eye on your motorcycle’s tyre pressure at all times – without the need for a gauge. Thanks to the colour-coded warning system, you can see at a glance whether your tyre pressure is correct or if air is being lost.

The caps are made from durable brass and are available for different tyre pressure ranges. Depending on the model, they cover the following pressure intervals:

• Range 29–30 PSI (1,90 bar - 2.07 bar)

• Range 31–34 PSI (2.14 bar - 2.34 bar)

• Range 35–37 PSI (2.41 bar - 2.56 bar)

This allows you to choose exactly the valve cap that matches your motorcycle and its recommended tyre pressure. Under normal conditions, the indicator shows green – if the pressure drops, it changes to yellow or red, allowing you to react immediately.

Ideal for touring, everyday, and commuter riders who value safety and convenience.

Highlights

• Automatic warning in case of pressure loss

• Colour indicator (Green/Yellow/Red) for quick status checks

• Precise pressure ranges available

• Brass construction for high durability

• Easy installation – simply screw on and ride

General Range for Motorcycle Tire Pressures

Motorcycle pressures are usually expressed in Bar (the common unit in Europe) or in PSI (Pounds per Square Inch, the Anglo-Saxon unit).

The majority of pressures recommended by manufacturers are between 1.8 Bar and 2.9 Bar.

Pressure Type: Minimum

Value in Bar: 1.4 Bar to 1.8 Bar

Approximate Value in PSI: 20 PSI to 26 PSI

Typical Use Case: Rear tire of a small/light scooter/bike; Off-Road use (Enduro/Motocross) to maximize traction.

Pressure Type: Standard

Value in Bar: 2.0 Bar to 2.5 Bar

Approximate Value in PSI: 29 PSI to 36 PSI

Typical Use Case: Front tire of a standard road bike; everyday riding without a passenger.

Pressure Type: Maximum (Load / High Speed)

Value in Bar: 2.5 Bar to 2.9 Bar

Approximate Value in PSI: 36 PSI to 42 PSI

Typical Use Case: Rear tire of a heavy or touring bike when fully loaded (with passenger/luggage); high-speed highway cruising.
