I'm looking at buying a 1992 Chevy k1500 extended cab as a project truck. The owner had it pretty much stock, and it currently has the 4.3 liter engine. I know the current tires need to be replaced as was just asking for opinions on tire size for it. I'm not going to do much pulling, just some trails and silver lake, so I was thinking 31s would suffice for now. I plan to swap to a bigger engine eventually, and making it a bogger, but use it as it is as a start.
