i have the truck listed in my sig, it has a pro-comp leveling spring spacers in the front, on the box for the leveling kit it said that the recommended tire size is a 265 however i had 265 on it before i ever leveled it, i am planning to get the 3 inch rough country spindles and a add a leaf or some blocks for the back to get some more lift, what would be a good tire size to put on with 5 inches lift in the front with stock rims? i am thinking about getting 295 since a guy here at my work had the exact same truck with just the 3 inch lift and they just barely rubbed on the front plastic. i am hoping that i dont have to trim but if i do i am not worried about it. what you guys think? also how big of a block can i put in the bak without buying new shocks?
