Tyre sizes

I know this has been covered before a couple times, but just to make it clear...

I have refurbished a set of 15'' steel wheels that I plan to use when offroading. Im hoping to put a nice set of MT's on these wheels, What would you recommend for tyre sizes to get? Either stick with the standard 195/80/15, or i believe the biggest that will fit is 215/75/15?

yes

I've got 235/65/15 there huge on a little freebie lol

Got 215/80R15 Kumho KL78 all terrains on mine, 28.5" diameter.

wouldn't put muds on it

You could at least put big ones on!
