The beaches in North Carolina aren't as scary as the internet would lead you to believe. Common sense goes a long way.

Honestly with a JK 4H or 4L will both work if you have a 4 to 1 T case I suggest 4H. Airing down to at least 15psi is going to help more. I'v seen a Rubi at Carolina Beach Lock all 4 and Bury itself. But that was Puffy loose sand it had not rained in 3 weeks lots of people were getting stuck. Key is to Keep moving but don't throttle too much.
