I have a chance to do either for my Sliverado 2002 Half-Ton 4x4. Put on new Teflon Predator wheels with new tires or have a Line-x Bedliner and Line-x around the whole truck's Rocker panels (my truck is red and the liner would be installed in black). Which one would you pick to do? Which one do you think would be of more value for the truck or better for the truck? Please provide your opinion. I plan to keep the truck for along time.
