How much would 18" DiscoII wheels run at the dealer? If I get the wheels, what would be a good tire/size for light offroading ingrassy areas?

 

About $450+ each. You'd be better off on eBay or craigslist. I see them all the time for around$350 for a set of 4. Even with freight to Japan, you'd be money ahead.

Stay with your 16" wheels, the tries cost less, they ride better, last longer and you get a better selection of tread designs.

 

Well, I disagree with the ride better, but the rest is all true. The higher sidewalls do wander more than shorter sidewalls, if you're doing mostly on-road and only dirt roads or other non difficult stuff then the 18's with a BFG A/T tire will do very well for you. If you're doing anything where you're airing down or climbing any kind of obstacle then the 16" option is far far far better. On the highway though the lower profile is much nicer. (IMO)

 

With a decent side wall, 16" tires wander no more then 18's.
That's why most people who wheel look for a reinforced side wall like the full 3 ply BFG MT's.

 

Yeah trust me stay with your stock rims im going down to 16" rims so i can actually put a decent set of mud tires on it.

 

I'd add proper air pressure.
