# FAQ & Trouble Shooting

## Common Questions

<mark style="color:blue;">**Q: What PSI should the wheels be inflated to?**</mark>

A: Inflate the wheels to the achieve the desired hardness. It is recommended that if used in a drive train, the out wheel should be softer than the center wheel or wheels. This helps with achieving the desired drop in the center.

## Common Issues

<mark style="color:blue;">**Issue: Not able to turn with wheels**</mark>

Possible Solutions:

1. This can be caused by having not enough center wheel drop in the drive train. If possible increased the center wheel drop distance.
2. If increasing the center wheel drop is not possible, decrease the air pressure in the outer sets of wheels and increase the pressure in the center wheels. This will do effectively the same as increasing the center wheel drop.

## 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://docs.wcproducts.com/welcome/wheels/pneumatic-wheels/misc/faq-and-trouble-shooting.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.
