Trying to lug a heavy load over sand can be an exhausting experience, but this revolutionary design makes it easier than ever.  Instead of relying on a wider wheelbase, which often digs into sand and dirt, these wheels replicate the track system used by bulldozers and military tanks to move more easily over uneven surfaces. The outer rim compresses when in use, exponentially increasing its track length. On sand and other soft surfaces, you’ll find that pulling your cart is much easier compared to standard puncture free Kiwi Wheels! In fact, we think this system is even better than balloon wheels for maneuverability. You don’t have to sacrifice performance either though; SandTrakz wheels are designed to handle hard surfaces too. Because they compress like suspension systems on regular roads and trails, you can transit seamlessly from hardpacks to sandy beaches with ease. With its patent pending design, SandTrakz wheels make lugging heavy cargo in outdoor environments as effortless as possible – get yours today!
