Stop in for a cup of coffee

Have not seen any whitewall in that size. Also, I think 215 is largest size for the 5.5" wide wheels I am going to use.

I just put these 225/60/14 on the stock 5.5" wheels with no problem. Un-mounted, the bead width was 5.5" so there isn't any tread distortion.

IDK about whitewalls but BFG makes redline tires in that size.

If you jump to the 15" wheel, you will probably have more choices.
