# Installing PD-Tyre

Install your PD-Tyre sensors.

Install PD-Tyre sensors on your vehicle.

## What you need

* **PD-Tyre** receiver box
* One PD-Tyre wheel sensor for each tyre you want to monitor (usually four)
* Compatible wheels and valve holes for clamp‑in sensors
* **Proteus Diagnostics** app (for pairing after install)
* Optional: **PD-Display** on the same vehicle

{% hint style="warning" %}
PD-Tyre wheel sensors are internal clamp‑in sensors. Fitting them requires demounting the tyre. Have the work done by a qualified tyre workshop unless you are trained to do this safely.
{% endhint %}

## Before you install

{% stepper %}
{% step %}

### Record each sensor ID

Every sensor has a **6‑character ID** (hex digits `0–9`, `A–F`) printed on the housing, often with a QR code.

Write down each ID and which wheel it will go on (**FL / FR / RL / RR**) before the tyre is mounted. After install, the ID is hidden inside the wheel.

{% hint style="info" %}
You will use these IDs in the app when pairing sensors to each wheel position.
{% endhint %}
{% endstep %}

{% step %}

### Check seals and parts

Use the gasket, nut, valve core, and cap supplied with the sensor (or a matching service kit). Do not reuse damaged seals or corroded nuts — poor sealing can cause slow leaks.
{% endstep %}

{% step %}

### Plan wheel positions

Decide which sensor goes on Front Left, Front Right, Rear Left, and Rear Right. Keep the same position map for pairing later.
{% endstep %}
{% endstepper %}

## Install the wheel sensors

{% stepper %}
{% step %}

### Demount the tyre

At a tyre workshop, demount the tyre from the rim using a tyre machine. Protect the sensor body from the bead breaker and mounting head.
{% endstep %}

{% step %}

### Fit the sensor to the rim

1. Clean the valve hole so the seal can sit flat.
2. Insert the sensor valve stem from the **inside** of the rim through the valve hole.
3. Seat the rubber gasket firmly against the rim.
4. Fit and tighten the retaining nut so the sensor body sits against the rim drop centre without twisting the stem.
5. Fit a suitable valve core and cap.

{% hint style="warning" %}
Do not overtighten the nut or crush the sensor housing. Follow the torque guidance supplied with your sensor kit or used by the workshop.
{% endhint %}
{% endstep %}

{% step %}

### Remount and inflate

Remount the tyre, inflate to the vehicle’s recommended cold pressure, and check the valve area for leaks (soapy water or a pressure hold test).
{% endstep %}

{% step %}

### Repeat for each wheel

Install the remaining sensors the same way, keeping your FL / FR / RL / RR ID list accurate.
{% endstep %}
{% endstepper %}

## Set up the PD-Tyre receiver box

{% stepper %}
{% step %}

### Power on the box

Turn on the PD-Tyre receiver box and confirm it has power. The app cannot hear sensors if the box is off.
{% endstep %}

{% step %}

### Place it in range

Keep the box in the vehicle (cabin or boot) where it stays powered and within Bluetooth range of your phone — and PD-Display, if you use one.

{% hint style="info" %}
If pairing later fails with a message about box power, check that the receiver is on and close enough to the phone or display.
{% endhint %}
{% endstep %}
{% endstepper %}

## After installation

1. [Connect PD-Tyre](/pd-tyre/getting-started-with-pd-tyre.md) in Proteus Diagnostics.
2. [Pair each sensor](/pd-tyre/pairing-the-sensors.md) to FL / FR / RL / RR.
3. [Confirm live pressure and temperature](/pd-tyre/understanding-tyre-data.md) in Tire Pressure Health or on PD-Display.

{% hint style="info" %}
If you rotate tyres later, update the wheel positions (or re‑pair) so the app still matches FL / FR / RL / RR.
{% endhint %}

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://help.pd1.sg/pd-tyre/installing-pd-tyre.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
