Wheel fell off while on cruise control

we were traveling in route from Reno to Palm Springs at the end of last week for our winter season and coming down 395. The right rear wheel flew off of the rig and bounced across the highway. Fortunately did not hit or hurt anyone. All eight lugs were sheared off. although I do not have TPMS, I do have pressure, sensitive valve stem caps, and they were all good. The tire is still fine but the end set inside the wheel are mostly ruined and the tire shop says the wheel needs to be replaced.

My rig is a 23 ambition triple axle. Although I had not personally checked the lug nuts for torque, I had the suspension upgraded at Quartzsite in January to the roadmaster slipper spring system. When they did the install, I was very clear with them about being careful with my lugs and the torque.Fortunately, I was able to recover the wheel, and the tire is still in good shape. We were 50 miles north of Bishop and the only TOW company that could handle an ambition with a low Boy quoted me $2600 and we’re not an approve.

We were 50 miles north of Bishop and the only TOW company that could handle an ambition with a low Boy quoted me $2600 and we’re not AAA approved. As it was mid afternoon on a Friday I opted to risk it and drove the rig on five tires at 20 miles an hour for the last 50 miles and managed to get to a tire shop in Bishop. They were very helpful and let me overnight in their parking lot And then first thing the next morning the owner of the shop went to Napa and fortunately they had a new studs and he had matching lug nuts at the shop. They had me back on the road by 10:30 in the morning. We were on good road, doing our typical 58 mile an hour cruise control drive down the freeway when this occurred. It did chew up my center cap in addition to the lug nuts and studs. The only other damage was the tire shop said he felt as if there was a little bit of play in the disc brake and that I should have all six wheels gone through now that this has happened to make sure there isn’t fatigue or stress on the other wheels.

Has anyone else had an experience like this or can offer advice? Does anyone know where I can get a replacement center cap?

One cause of this is improper torque. With loose lug nuts the wheel studs will break. Excessive torque would cause stud fatigue and subsequent failure. It is for these reasons I verify torque prior to long trips and periodically throughout the year.
