Buy a 12vDC air pump at Walmart for $12.00
Go to beach, air-down to 17-20 psi, get great traction.
Done at beach, re-inflate tires to normal pressure.
Go home smiling.

$12.00 pump? Come on. Those things can't fill up a beach ball let a lone 4 tires. If you plan on off roading often and will need to air down, go buy a portable quick air compressor from 4 wheel parts. They come in a case and are very reliable. They are $200 to $300 but are worth every penny if you plan on getting into the hobby of off roading.
