I would not recomend the BFG's for highway use. I've had them on a couple different trucks. One I switched to Super Swamper SSR's ( highly recomend ) and my current truck I switched to MT Baja MTZ's. Both of these were much quieter. My current MTZ's are even 3" wider and still make less noise. I can't speak for the ATZ's, but would guess they'd be even quieter.
