16.5 tire options?

Interco tires still makes some tires in 16.5", but they're all mud terrains. I agree with mopardug and 17" wheels are probably the best solution. 16" truck wheels are going extinct pretty fast so the 17"s should give plenty of reasonable options for years to come. I typically prefer take-off wheels from stock trucks. They are American made and much higher quality than most aftermarket wheels. Plus FB Marketplace are full of good 8 lug options in the 8x6.5" bolt pattern.
