With the addition of numerous electronics to modern vehicles, especially our front cameras and radar sensors, lifting your truck isn't quite as easy as it once was. You may now have no issues, intermittent issues or constant debilitating messages and complete deactivation of some features on your truck based on aftermarket modifications. Namely tire size changes and lift height. Without making this a long drawn out blog post we're going to just hose you with information. Below you'll find a chart broken down by the most common aftermarket wheel sizes and their corresponding tire sizes and lift height followed by an annotation of whether the PCS system should be disabled to avoid errors on the dash. If you're one of the people that immediately sees a table of numbers and says, TLDR. This next bit is for you, if you stay below a 37" tire with a 3" lift, you're likely to be problem free. Please see the important considerations at the bottom.

*Important Considerations*
Not every tire manufacturer produces a true to height tire, it is recommended that you confirm the actual tire height with proper air pressure
