as a police officer in ny and very familiar with tints i can tell you that on a sedan 70% light transmittance is the legal limit. Only on the rear window can you have whatever tint you'd like. however on a suburban veh like the cherokee you can have the rear pass and rear drivers side windows tinted, as well as as the rear window. just so everyones aware 70% tint is basically a stock clear window. i know a lot of people with tints and most jurisdictions don't enforce it as much as others. NYC enforces tints heavily, so beware.
