The first question is, do you want bigger than stock diameter? Or the same size diameter as stock? Jerry's truck is a great example of an oversize tyre. Not sure if there is too much out there for a an off-road tyre in a stock diameter. Unfortunately, I think you'll have to be like the rest of us and do some internet searching. There are many great tyres out there for example: Goodyear, Goodrich, Cooper, Dunlop, Bridgestone to name a few. Mostly its personal preference. Bob
