Just so we're all on the same page with our +&-", my sling with Accuride air suspension from RevDynamics has tires that are 3/4" taller (radius) than stock. When my shocks are deflated, the frame is 2" off the ground with the plastic buckets only 1" off the ground. When they are fully inflated, the frame is 8" off the ground (take 3/4" off these numbers for stock tires). For driving, they do not recommend you go over 90% or under 10% inflation. Even with my taller tires, 10% inflation is very low and I only do it as a parade mode.
The controller let's you go to any height you want and allows you to save 3 of those as ''presets" and the computer will maintain those heights even if loads change. I've set my 3 as "parade" 2.75" off ground, "freeway" 4.5" off ground and "town" 6.5" off ground. If I need to go higher or lower, I can manually do it at any time. Those heights would be the same if I had stock tires as well. I can go lower if I adjust the shocks to be stiffer too. I currently run at 7 clicks from the softest (17 from stiffest).
