Tuff Country recommends a 33” x 12.50” tire with this system. The stock tires and wheels can be used in conjunction with this lift kit. Our tire and wheel fitments are only a guideline. Different production times or tolerances will vary and this size should only be used as a starting point. Each vehicle is different and will need to be treated as such.
Before installation begins, Tuff Country EZ-Ride
Suspension highly recommends that the installer performs a test drive on the vehicle. During the test drive, check to see if there are any uncommon sounds or vibrations. If uncommon sounds or vibrations occur on the test drive, uncommon sounds or vibrations will be enhanced once the suspension system has been installed. Tuff Country EZ-Ride Suspension highly recommends notifying the customer prior to installation to inform the customer of these issues if they exist.
Make sure to use loctite on all new and stock hardware associated with the installation of this suspension system.
