Tire separated from axle

While traveling on I-95 North near the border of Georgia and South Carolina a vehicle pulled next to me and yelled out that I had lost a tire. I pulled to the shoulder and the passenger side first wheel on the triple axle was gone. The rear panel of the camper was damaged and by the grace of God no other damage. The vehicle that stopped us had suffered damage to their rear passenger rear quarter and again the Lord blessed us, no injuries. The lady passenger said when she saw the tire bouncing towards them she thought it was going to go through the windshield. Insurances and warranty will take care of damages. Unknown caused for all bolts to failed. Internet is not good, may not be able respond to comments.
