The G10 wheel is made exclusively for Mercedes G-wagen trucks. This is a forged alloy wheel that is incredibly strong because its forged and specially machined for the uncommon bolt pattern of the G series trucks. since they are forged one piece alloy wheels they are very light which is important to keep rotational weight down. A unique feature of this wheel is that it has a specially designed inner bead lip that virtually guarantees the tires not to pop off the bead when aired down for off road use. It is safe to run these tires at 10 lbs air offroad and in sand without having to worry about lossing a bead.
