Shopping online for new tires found some some all season choices with higher wear ratings and lower costs. Hankook Ventus AS, Bridgestone Dueleer H/L Alenza, and Toyo Open County H/T. If I order set, is there any precautions for local garage on how to lift/rack vehicle to mount ties without damaging the air suspension. Manual says to set suspension in 'off road' height and lock before lifting but no instructions on how to lock the suspension in the off road/extended mode?
