When you put your combat rims together you should use a torque wrench and set the bolt to 60-70 ft. lbs. But hey be sure set them ALL to the same torque reading!
Combat wheels are identified by eight bolts holding together the two halves of the tire rim. When removing a tire, first remove the wheel and be sure to deflate the tire before removing the rim nuts. After removing the rim nuts, remove the outer rim nuts, remove the outer rim then remove the tire after which remove the beard locking ring and tube from the tire. Mounting the tire is the reverse procedure. Do not put too much air in the tube when mounting.
