8:00 x 4" tires

I have the factory tires on my supercruiser. How well do these seamingly wide tires do on sand bars?

I own a PA-12, unless you are completely certain of the beach you are landing on (i.e. you have walked the landing are, you need at least a 8.50-6 tire if not bigger) any off the field landings should have been you walking the landing area so that you know exactly what you are getting into.
