Many have opted for BF-full. A pressure of 0.5 to 0.7 bar for a nice full-BF versatile. Or beach are hard or soft, with that pressure is always good to drive. But clearly, that BF-full bands on a hard and / or wet beach is not always the best combination. Disc wheels have a hard and / or wet beach is enough proven benefit. Again not working well in combination with a soft and mullet beach. Tires should be interchangeable simply faster. Maybe in a way you have some bicycle wheels 3 seconds can change?
Drive Wheels: on a beach wet and hard very efficient and also aerodynamically sound. The tyre pressure is important for speed and efficiency. The pressure is not only a great influence on the rolling resistance and the suspension, but also the lateral force. Instead of adding more weight to the lateral force to compensate for instance you can think of a slightly lower pressure. Not too low because a high speed if you never get with a low tyre pressure …
