Hey guys; I have a 1994 K1500 1/2 ton Z71 package, and the door sticker says that it came stock with LT tires. I was just wondering if I can replace them with P rated tires or if it is really necessary to get the LTs. I don't do any towing, and at most haul a yard of bark chips or gravel in the bed if working on yard project. I noticed that most newer 1/2 ton trucks come from the factory with P tires. Just need to know before I pull the trigger on some new tires. Thanks!
