I don't think you want 30's on a lifted truck and not even a stock truck- way too small.
Try some 7.5r16's (32"), 8.25r16's (33-34"), or 235/85/16's (32"). the 235's are the metric equivalent to the 7.5r16's that are found all over africa and australia, only the 235's are a little bit wider at about 9-9.5 inches.
I agree that the 30's would look somewhat puny on a lifted 60 series. CCOT believes that they're the perfect look for the stock suspension, however, so that's what they use on their restorations. With a 2" lift, I'd go with a 31 or 32 skinny.
