Bought a brand new jato. Broke the tiny knubs it comes with so I upgraded to jato specified bandito street tires from duratrax. The back axle is hex and front is circular bearings so the hex rear bandito tires fit perfectly then I tried to fit the front but the circular bearing upfront did not like the bandito hex. So I trade the 2 new banditos for bearing fitting ones and find out the center hole on the tires are to large for even the nut to hold. I try to research if maybe it's a bearing size problem but no luck. I call tower services and they tell me it should have had hex fitting on all four corners of the car, after trading in the two hex I had in the first place. Another advice they had was to get a hex conversion kit for the front and get the hex wheels back. The big deal is that there is no information at all to come with the jato on the specified duraTrax wheels after spending a fortune to get the parts and car for christmas. Converting to all for hex when they should have been that way in the first place is a big waste of money. Doing one thing needs three things to do.
