Well i don't read Tenjou Tenge and i am not a fan of bad jokes thrown in my face all the time. I don't mind the jokes here and there, i for example enjoy the fat guy skating on his head and Akito being gay and so on but when they throw in 3 Ringo sexjokes in 3 chapters in a row in the middle of a fight i get a bit pissed.
A good manga needs both char development, story, action and some comedy. It feels like Airgear skips most of all those things and throw in a bunch of crappy sexjokes in some chapters and i am not a fan of that kind of shitty immature humor. "oh my god lol look at her ass, she dressed up in a swimsuit HAHA" yea that's funny eh? Well i don't think so.
