My OEM 275/70R18 tires on the F250 were the same diameter as my 245/70R19.5 tires. I considered buying three so I had one high rated spare or four and use the OEM as spare. I chose the latter and figured I could always put the OEM up front and keep the high capacity in the rear. I never had a flat tire to confirm my thinking, but it gave me piece of mind in my travels.
