Define "large" = Diamter and/or width ?

Where will you use the vehivle.

There are two philosophies.

a. Wide tire will float (or not)
b. Narroe tire will cut through the loose ground and reach solid ground

If its about diameter then get the size that matches your gears and the
size that will fit WITHOUT rubbing when flexed.

More aggessive but smaller will be better.
