OK, more stupid noob questions. Experience with smaller vehicles, but doed not seem to always be related to these big guys. When replacing wheels, is it necessary to glue the tires to the rim since they are mechanically beadlocked? Is it necessary to glue the foam inserts Do all the foam inserts work for all the different tires and beadlock rims available? Appreciate any help available guys! **** Edit After looking at the tower hobbies site, I have determined that I am confused. The size of the rims vs sizes of the tires do not seem to coincide. How much difference between the OD of the rim and the ID of the tire can be tolerated? I am interested in the badlands tires (cause of the ad here), but I would really hate to purchaes tires and rims and have them not fit each other..... Thanx for helping me in my stupid noobness!
