Ken, with regard to your question about lifts, I am not sure if this will help, but I think I had a similar question about mine. You might want to check out http://www.quadratec.com/jeep_knowledgebase/.

I am really interested in the airing down issue because my tires are only 30x9.5. I am looking at air compressors because I think one would be a good idea and I was advised to get one in another post, although I hope the law of diminishing returns would not apply here.
