New to this site, so don't know if I'm posting this in the right section, but I need some 16.5x12.5 rims, not looking to spend a whole lot of money, looking for some advice

 

16.5 wheels have kinda gotten phased out, getting harder to find, but you should be able to find some used on Craigslist. Or

^^^not very cheap though, you didn't specify lug pattern. I know you can get some hummer H1 wheels in a 16.5 and they can weld in new centers for what ever lug pattern you want, also do different styles of beadlocks as well, still not cheap though.

 

Gonna take a shot and say you need the 16.5" rims because you want to run the 37" Goodyear Humvee tires because they are cheap.
If that is the case I would recommend you not do it.
I drove humvee's in a few different environment typs.
The tires suck, especially when you put them on a truck that weighshe less than half the truck the tires were designed for.
