Go with those Nitro Mud Grapplers, with 18s those things would look crazy. That and no one has 18s with 33s yet, it would be cool to see something different.

 

there are a couple of people with 17's and 33's but 18's ...im xcited!

 

You know...you can always go metric on the size.

 

the only 33 inch tire i can find for an 18 inch wheel is a 305-65-18 BFG All Terrain

 

if you decide to get the mud grapplers you will be very pleased with them......i'm running 33x11.50x16's right now and i love 'em! they are amazing offroad and ride suprisingly well on-road (although tread wear isnt the best). and they are the best looking tire period! i almost went with the 33 and 18 but i settled for 16's and im kinda glad i did. although 18's wouldve been hot.

 

heres a pic of my setup.....hope it helps you decide

 

I used to love the mud grapplers, but 7 out of 10 trucks are rolling on them around here. I think I see more nitto's than I see BFG's

 

as another option you may want to look into Toyo M/T's. they are in the same price range as the nitto MG's but they have way better tread life and ride smooth too. they were my plan b but i went with the more aggressive option

 

what is the metric size again for 33's? isn't 325 pretty close to 34's?

 

I believe 33s are 305? But It might be drastically different with 18 inch wheels.

 

325 and 305 both refer to width.....you need to know the rest of the size to figure the height

 

nittos actually get Cheaper as the wheel size goes up, atleast for the MTs
