Advice please? Over tightened rear wheel after tyre fitting

[Eunuch]

Can anyone tell me if I'm going to have any issues after the numpty local tyre fitter left my rear tightened up to '90-100' NM?

I've had the rear Tourance replaced (its the first replacement) as I'm on my summer jollies next Fri. As I left the tyre fitters he told me he wasn't sure what the rear torque should be and as other BMW's he'd done were 90-100 NM he decided to set mine to that too. He did that while I was in the office paying for it but to be honest at the time I didn't know what it should be and only now checking realise it should be 60NM and he's over tightened by at least 50%.

That was on Weds and just checking I want to undo and re-tighten correctly (thankfully my Halfords one goes up to 60), but before I touch anything I'm after a bit of advice. The short ride into work that day and back home in the pouring rain with a new tyre is nevere the best experience, and maybe the handling felt weird just because of that, but I'm never normally bothered by the rain. I guess its done about 5 slowish miles since the tyre was fitted.

Advice welcome as I go on my biking hols in 4 days! Is just correcting it enough or could he have caused any rear wheel (bearing) damage?

Thanks

Doubt it would have damaged the bearings, might have started to strip the bolt threads IIWY I'd have a look at the bolts ( because they're easier) to see if there's any metal that's been picked up by them when they were over torqued. Then if possible have a look at the threads in the hub.

I'd guess that the hub uses inserts in it, it would be worth seeing if they're located "properly".

If you're really not sure / not happy with the tyre fitters why not ask the dealer to replace the hub and bolts and claim it on the insurance?

Tricky to see how he is going to claim under the insurance.

if it werent safety critical I would say just put the facts down on paper to the tyre company and then see if anything developed. Probably not.

But since its a wheel you cant really afford to take risks so ask BMW technical for their opinion. I wouldnt trust my neck to the answer on this forum from an unknown person.

My advice would be to tell the tyre company that you will check any potential damage with BMW and make sure they understand that they are liable for any damage they have done.

They have a duty of care to put the wheel on properly and obtain the correct torque settings. They will be fully insured against this sort of thing and if they are a reputable company, they will be more than helpful if they been proved to have have ben at fault.

All of the above but whatever you do replace the bolts anyway before you do any serious riding as they may be stretched (and therefore weakened) and if so will stretch further or shear if put under additional stress.

And you dont want that do you!

I had a new rear fitted to my K12LT yesterday and before the fitter replaced the wheel he referred to a booklet which listed all bikes by make and model and had the torque settings for wheel nuts, brake calipers etc. Surely your tyre fitters will have the same documentation and if so why didn't the ham fisted muppet refer to it; if they haven't got the booklet then that would suggest that they hazard a best guess for all bikes which is unacceptable and unprofessional and of course dangerous. I would question them on this if I were you.

The fitter I used by the way was Robsom Racing at Shipston on Stour, he is well known on this forum as he does very good deals on Tourances.

Where have you got the figure of 60NM from?
The 1150 manual has the bolts being initial tighten to 60 then finally tightened to 105NM. I know from your sig that yours is a 1200 but it might be worth checking your info again.

It is 60Nm, see here.

the reason they are 60nm on the 1200 is because they are now a 5 stud fixing

Thanks for the replies

I spoke to Bahnstromer earlier and they think I might have got away with it. If anything the 'slides' that are in the hub that the bolt screws into could be damaged. Only way is to take it out and have a good look. I'm at the tyre fitter 8am tomorrow so we can have a peek together.

More to come ...

I'd get some new wheel bolts if you want to be really safe.

You really need to check the threads on the hub VERY carefully. As was mentioned above, look for pieces of thread that might have been pulled out.

The bolts may also have strained threads. They are a relatively easy replacement. Get them to pay for new ones.

Talk about arsey staff. The moment I politely (please, thank-you, I'd really like) and accurately (spoken to BMW garage, confirmed torque, need to carefully check) ask the tyre fitter do raise the bike again (no I don't to crawl around on my knees looking at the hub) everything is just soooo much effort. Imagine if I'd gone in arsey.

Bottom line is all the studs looked A1. No metal or mis-shape on any of them. And the hub slides looked good too. So I can happily go to France end of the week.

The best line from the fitter was as I left - "I'd have set these to 100Nm, so if it fails now its BMW's fault".

My advice: give Roadwheel Tyre & Exhaust in Cosham, Portsmouth a wide birth.

Appreciate all the feedback.
