 1.Low Pressure Polyurethane Beach Wheels for more heavy duty, ambitious use.2. wheels are equipped with unique, pliable, pneumatic tires that will roll, even glide, over soft sand, turf and other challenging terrain. The tire’s low pressure permits rolling heavy loads over unstable/uneven ground with ease. These balloon wheels will not sink or plow into soft ground. They are great for use on delicate surfaces preventing indentations, as well as providing shock-absorbing qualities.3.These low-pressure balloon wheels inflate to only 0.17 bar, which means they’re soft. So soft they glide over sand, flattening it along the way. Normal wheels dig ditches, and that’s hard work.
