lets say that you put calamini front and rear tube bumpers on you rig and some AT tires,,,,,        is there any problems with street legalities...  as far as you all know....      i live in pennsylvania..   thanks

How tall are the AT tires

Most likely not... in a lot of states, the max bumper height (at the lowest point on the bumper) is like 24"

I live in PA also. You'll be fine with the tube bumpers. The AT's will also be good as long as they don't stick out past the fenders. About the only other thing that PA is a pain about is auxilary lights or off road lights mounted above the level of the headlights. Anything above the headlights needs to be covered while driving on the road. Of course that depends greatly on just how cranky the cop is. I have a pair of small clear driving lights mounted at the top of my windshield and have been driving around for over a month with them uncovered and have yet to have any law enforcement say anything about them. Of course I don't use them on the road, but they are still functional...
