This is for the R12 with inflatable tires all the way around.

Keep in mind, unless they changed it, this cart does NOT have a BRAKE on the Tires. If you load on inclines or hilly venues, stay away from this as the cart will roll all over the place and you'll see your equipment go for an unexpected ride down the hill! lol

Even in Florida, there are hilly areas at loading docks, or walking down to the beach areas so I feel the BRAKE is VERY important for a CART. Otherwise this is a great price. Perhaps some clever member can retrofit a brake for this unit.
