Are you keeping the stock wheels? Wheel width and offset are as big of a factor in what fits as the tire size.

You're front springs look like stockers with an add-a-leaf so my guess if 1"~2" lift, 33's should fit on the stock wheels but if you use bigger wheels I'd bet they'll hit in the front.

Fyi, a stock front suspension will measure 8.5" between the bottom of the frame and the top of the axle tube, any difference in measurement is your amount of lift.
