Flotation and PSI keep it around 4-6psi (calculated from vehicle weight/tire foot print in square inches) and you can drive where you can walk. In 1999 I built up a zuki with 6" lift and 31x10.50 would drive it out into the bay at South Padre Island fishing out of the back, would get "do you need help" all the time thinking I was stuck 100yds from shore. If I could walk it I could drive it never got it stuck. Zuki 31x10.50 tires were fine even with valve cores removed, 0 psi in tires due to light weight vehicle. But it drove like a golf cart, floor it and see how fast you could go, against wind 55-60 with wind 65-70
60hp motor no top end but plenty of torque in low gears. Brother in law still has it.
