Spacers on a 95

With a 1" spacer up fron on a 95.5 model, whats the max tire size you can run? And do you need to do anythinf the back?

 

i have 1" spacers up front, and the front of my truck def looked higher in the front. After I did the spacers up front, i went ahead and bought all pro offroad 1.5 shackles that lifted the rear up to match the front.

after the spacer lift, before the rear shackle lift




after the rear shackle lift was added

 

not that much of a difference, but the truck at least sits level
