Have a 17 longhorn with air suspension. Wanted to change tires from original sra's so have tried nitto, cooper, hankook, Michelin. All in stock size 275/60/20 standard load. Seems when go to a different tire I pick up more road vibration on rough roads except for the Michelin. They are smoother than the sra's and handle all conditions very well so I should just stay with them but they are a bit thinner than I like and keep looking for that tire that will be a little beefier looking but end up not liking how much feel road when change tires. Anyone else experience this with their air suspension or am I being "oversensitive." Never experienced this to this point with regular suspension.
