# Wheel Options

{% hint style="success" %}
Regardless of which wheels you choose for your EasySwerve Module, they should be replaced as the tread wears down due to regular use. For more information, check out our [Wheel Evaluation Documentation](https://docs.revrobotics.com/ion-build/help#wheel-wear-evaluation)!

{% hint style="info" %}
To ensure your Traction Wheel - MAXSpline - 4in - Hard is the updated version, look for a star (circled on the image above) on the tread. We do not recommend using older Traction Wheels with EasySwerve because they are significantly more susceptible to [delamination and rapid wheel wear](https://docs.revrobotics.com/ion-build/help#traction-wheel-evaluation).&#x20;

## 4in Spiky Wheel - Aluminum Hub & Tread

### Overview <a href="#overview" id="overview"></a>

The 4in Spiky Wheel and it's associated tread are designed to be used with the 4in EasySwerve Module. The Spiky tread provides superior grip and performance, especially on carpet. The one-piece split tread design allows for quick and seamless replacements without the need to fully remove the wheel. As a consumable component, these treads are built for performance but will naturally wear down over time.
