I have a set of 4 Real 16x10 wheels. Excellent condition. They currently have a set of nearly new Truxus STS 33x13.5 tires on them but I will sell them separate. I bought them off a truck pulling friend of mine who had Real make them with specific offsets for sled pulling (or dirt drags). The front wheels have a large positive offset so that half the tire tread width tracks outside that of the rear set (which has a high negative offset). Still meets all applicable rules for track width. If you are interested I can get some pics and price these.
Thanks
John
