I just installed a new suspension lift, why is my ride harsh, stiff or rough?
Assuming you installed new tires at the same time as your lift, there is a good chance that your tires have been inflated with a PSI that is too high. For optimal comfort and even tire wear. you should not run the recommended PSI listed on the sidewalls of your tires. Typically this will be way too much. On average for a 33″ tire, I would recommend that you run your tires at approximately 28-30 PSI. For a 35″ tire, I would recommend running approximately 26-28 PSI. For a 37″ tire, I would recommend approximately 24-26 PSI.
