Hopefully an easy question: 1987 K5, stock suspension right now, came with 31" tires. Seems to be plenty of clearance available to go to 33's without a lift. Am I right? I'd hate to go through all that trouble if it didn't work. (A lift is coming though, so I guess I can wait if it won't work). Eventually I'm only going to do a 2-3" lift and plan to keep 33's on her, but I'm itchin' to do the tires now, know what I mean?
