Will a 38x15.5 20 fit on a 20x9 wheel ok?

 

I'd say you're probably going to want at least a 10" wide wheel, if not more.

 

Your tire question is little vague.... What kinda tire?

Its as simple as going to the specifications page of the tire you are looking at and they will list the ideal wheel size for the specific tire... and being that its such a big, wide tire.... id say nothing less than 10

 

I haven't decided for certain yet. But I'd either go with the Toyo open country mud tire or another set of Nittos. Probably the mud grappler this time. (but they are sooooo loud)

 

I ran 37/13.50/20 toyo MT on a 8.5 wheel , on toyo website they list what size wheel width will work with their tires

PS I just looked it up on that tire with toyo's 11" to 13" wheel
