I want to put a new set of tires on my 1986 K5. I will do mostly road and beach driving. I was thinking of of getting something really wide like a 14.50 or even a 15.50 cause of the beach driving. Will they fit on my stock K5?? Will they scrub when I make turns?? Am I going to wide ?? Thinking of 33's. Help me out new to this. And thanks for your help.
