I just got my '72 K5 a couple days ago. It was completely restored with the exception of the wheels and tires. We was looking for original and never found them. I plan on lifting it with a 4" shackle flip in the rear and 4" springs in the front. I have a '75 K5 trail rig already, so this will be mostly paved roads, light trails and mud runs. It will see some occasinal rocks and fairly off-camber situations. I felt the lift componenents were a good fit and it will give it the look I want for the road. It will be a daily driver. I was planning on going with a 15x8 wheel with a 3.75" back spacing. The lift will not be done for a couple months, but I need the tires now. Could I fit tires with a 33" diameter and 12.6" width before the lift is installed? I only want to run 33" or 34" with the 4" lift. I think 35" will be to big. I do NOT want to trim the fenders. Would it make any difference if I went with a 16x8 wheel that had a 4" backspacing?
