im running 37' goodyear MT on 16.5 wheels with 4.5 backspacing. whatcha wanna know?
the pros of this setup are the tires are CHEAP! and its got a descent tread. so far i like em, but they do tend to dig, which isnt the best on sand. also the sidewall tread is non-existent, but that hasnt been an issue ...yet.
the cons of this setup is the 16.5 wheel. a 16.5 wheel does not have a safety lip like a 15 or 17 inch wheel would have.
iv been reading up this week into beadlocks and recentered hummer wheels seem the best bang for the buck. im still researching but from what i gather
a beadlocked 16.5 is the same diffrence as a 17 wheel with a safety lip. both help you air down but if you still can lose a bead if you push it to far.

you can get a 16.5 beadlock for cheap but if you want a double beadlock he sells pvc inserts which pinches the inner tire aswell. if you get the pvc insert tho, your talking a pretty penny to air down.
