seon,
I did a similar install - if I had to do it over again - I would go for larger diameter tires and I would lower the camero clip about 1 inch or so relative to the truck frame to get the whole truck up off the ground a little more.
I ran BF Goodrich 50 series tires on 14 inch rims and had a hard time negotiating grassy fields with ruts at car shows - the front bumper would scrape. Width / tire clearance was no problem however.
