Tire/rim and train horn recommendations ??

[deathshead67]

I'm looking to get some black rims maybe rockstars, what is the largest tire and rims I can get without a lift.Maybe the leveling kit to bring up the front but thats it. I drive mostly in the city ( in New Jersey) but looking foward to some off-roading (nothing to crazy) !! And I'm looking to get the loudest air/trains horn available for around $500. What should I get? Thanks!!!
