RennTech Oversized Tire Module

Why do you need a tire module?

By installing a tire larger than a 275, your wheels will turn slower for a given speed (lower wheel RPM), which will, therefore, cause the computer to indicate a problem. The ECU will then disable Adaptive Cruise Control and Emergency Brake Assist.

The good news is that Renntech and Owl finally have a fix. Plugging in the Renntech Tire Module to the OBD2 port on your van will change the acceptable tire size inside the van's ECU, allowing all systems to function as intended. You can then remove the module and you're done.
