Dangerous Situation

FYI..Had the snow tires mounted on my brother-in-law's 06 LBZ a couple of weeks ago. Took it into the local tire shop where he had bought the tires and they do it for free. Both sets of wheels were after market but the snow tires didn't have the center hubs with them as I didn't see the point of ruining them with all the crap they spray on the roads in the winter to help keep them clear of ice.

Anyway when I picked up the truck, (brother-in-law winters in Arizona) I noted they put the center caps on the wheels from the set that came off. I didn't think too much about it and didn't say anything to them. I drove the truck into our remote cabin to check it out and make sure everything is OK. It's about 40 miles one way and the last 20 are pretty rough. Wasn't too much snow and was a bit sloppy due to melting. On the way out about 15 miles from home I noted a bit of a clunking sound coming from the left front. It sounded like a tire coming apart. It was dark and when I got out to check I couldn't see or feel a thing. I didn't have a flash light with me either. I limped it home at about 15 mph and drive it into the shop. Couldn't see a thing...But I didn't check the lug nuts. My fault. I jacked up each side of the front end and shook the tire and wheel, both were solid. I left it for the night and went to bed.

Next morning I was going to take it to the dealer to see what the hell was going on and when I checked the left front wheel I could see one lug was broken, two others were missing and the rest had back off about half way. Why I couldn't see that the night before is beyond me, but the reason I couldn't move the wheel was due to the ice and snow that had built up behind the wheel and it melted over night.

Took it to the tire shop and they couldn't believe they hadn't torqued that tire as it is the first one they always do and their best tire man had done the job. It ruined the wheel so they put on a stocker till they could find one or are going to replace all the wheels. As I got ready to leave I remembered they hadn't gave me back the center piece so I went back in to get it. The manager brought it out and the edge that seats against the wheel was cracked and chipped in three places. I told the manager that seems odd and that they were not the correct centers for the wheels in the first place.

The old light goes off in his head. Seems not all wheels seat the center caps in the same way, some are beveled and take a flared end on the cap and some are flat like a routed edge. The caps were beveled and the new wheels were flat so the beveled edge would not let the wheel snug up tight to the rotor assembly and there for was able to work loose. It appears at least on this set of wheels it was only the front tires. We pulled the other caps and sure enough the right front cap was also chipped and broken.

So sorry for this long post but if you change wheels and try to use another set of center caps other than the ones that came with the wheels make damn sure the seating edges match.

Glad the wheel never came off on you Ken. that could have made for a heck of a ride. When i worked at discount tire we had a guy do the same thing to a customers car, caused a wheel off and injurys to the driver. next thing we knew, we all had to have a big meeting about it in the store and made sure everyone knew about the differences and to make sure you never mixed caps form other manufacturers or wheel types. This same thing can happen if you leave the little rotor clips on a studs and try to mount a wheel with no recess around the back of the mounting surface. We had a car that kept having loose lugs and once we took those little clips off, they stayed tight

I'm sure he's 'the best' tire guy and there are many others I'm sure but 'I'm' MY OWN best tire guy!

I have tire shops mount and balance tires as I cannot from there I mount the tires myself on vehicles. Have been doing that for years!

The only time is I have a flat on the road obviously but I do check their work asap. Thankfully no one was hurt on a very very simple over look. Easy mistake to make

That is bullshit Ken but glad nobody got hurt. Its funny how the simplest thing can be a huge safety hazard. Like Mack I too do my own tires other than mount and balance. I had discount tire rotate them once while I was out to lunch and I watched them pull it in and jack the front of the truck up by my lifts sub frame edge which is an 1/8" lip that I'm surprised didn't fold over and send my truck careening into the ground.

I am to blame somewhat. I always watch then they mount and torque the tires. I didn't this time due to being in the back of the shop and not allowed to go there. I did note they used the wrong caps but didn't say anything, and I didn't know the edges that contact the wheel are different on different wheels. I drove a very very tough piece of road. Steep winding road next to a reservoir. One turn in less than a 5 mph corner to the right as you come down into the canyon. Weather was totally crappy, 33 degrees and blowing rain and snow and no where to really get off the road. Not my truck so didn't have what I normally have in my trucks, good flash light etc. so I was a little lazy not making sure of this stuff before I left.

If there is one thing I learned in the Navy is if you had a problem with something it was usually whatever you had last worked on. In this case the tire change. I had been in and out of 4x4 so I didn't know if I had screwed an axle or the hub or what, and didn't heed my own advice. Again lazy. Yes I was damn lucky the wheel didn't come off. Hope this thread gets other guys to ck these things too.

I dunno if I'd blame myself as you put the job in their hands and it is their responsibility to insure everything is correct.EVERYTHING including the centercaps fit.

You could have been moving down the highway at 80 MPH. Gratefully it was a non major incident and they will take full responsibility. Make sure the new studs are seated correctly! :)

A buddy of mine got a wicked wobble, by the time he stopped he had only 2 studs left the rest were busted off. He tightened them up and limped it home.

I try to do my own maintenance too, but it can happen to anyone. I recently had a CV come unbolted from the axle side while driving about 50 MPH down a gravel road..... somehow I got it stopped and bolted up with some new hardware and it seems good as new. Stupid me to not have re-torqued it after replacing the CV last summer.

Yup. I've run a bunch of different wheels and tires, from Alcoa to Zenik. Two things about the caps: Some rims are chamfered and some are c'bored to accept the cap lip. They are not interchangeable. Some rims are also hub-centric, in other words, the through hole is the same size hub dia. These cannot run caps that come through the back, they must be snap-on front caps.

Thank goodness nobody was hurt. Wheel failure can be pretty serious.
