How tight are your nuts.....?
Discussion
Very simple and probably very dumb question, but do you guys torque your wheel nuts to a prescribed level??
Been helping UKKID35 a couple of times on his re-build and he mentioned he torques his nuts up to 130lbs/ft.
I did that to mine last night after taking a couple of wheels off to adjust suspension settings, but 130 really didn't seem very tight, so went up to 144. Do I risk snapping the threads at 144, or do you just do them up as tight as possible?
Thanks

When I was doing my apprenticeship the wise old mechanic would say to me "Tights tight, too tights broke". Really useful 
With the wheel off the ground I do mine up finger tight to start, drop drop it to the ground, then pinch up. Never lost a wheel yet.
Well, except for the time I was overtaken by the NSR that came off my old BMW - but that was sabotaged.

I was told this by someone too. A very old chap at a hillclimb once. He set up someones carbs by ear in a couple of minutes. They later turned out to be set pretty much perfectly, the owner couldn't believe it was done so well, nor could the specialist he used at the time. I asked why he was so surprised - I've never played with Carbs, I am relatively young - he said "its tricky enough to get them that close normally, let alone quickly by ear, but the thing that really gets me, is that the guy is deaf as a post." 
Wise old mechanics, I have alot of time for them.
Always torqued up to the settings mentions on the sticky, when i was rebuilding and rebushing my suspension i found a Tuscan site that had some of the missing settings and used them as most of the parts are carried across,
I have a grand cherokee with the same wheel flange and stud set up and 90-120 ft lbs is recommended.

80 MAX.
The studs/ nuts set up never feel 'tight'. I would not go anywhere near the figures mentioned... I've seen a wheel come off another car due to this (non TVR), at 70 - he was lucky to get away with as much damage as he did...
80? Really? Wow. Time to loosen my nuts asap....and there's no chance of them coming off at 80?The studs/ nuts set up never feel 'tight'. I would not go anywhere near the figures mentioned...

I checked with the garage when I needed to do mine - I can't find the figure now, but it was something like 90lbs/ft, way more than the sticky on here. I questioned them about it and they were sure.
Still, six years later and I've not lost one yet, nor damaged the threads.
If in doubt, check with the guys who maintain it.
Sorry to have no clear answer!

I can't guarantee anything, we only tested them at 80 for about 90k miles... 
80 is fine as long as the studs/ nuts are fine, I'd recommend checking them over occasionally, but I'd do that on any car and at any torque. I'd keep sub 100 personally, I would be very wary of any damage caused by overtightening beyond that.BCA said:

It didn't feel like much effort to get to 130....either 6 months out of the gym hasn't affected me very much or my torque wrench is utterly knacked....I'll de-torque to 90 and take it from there. 80 is fine as long as the studs/ nuts are fine, I'd recommend checking them over occasionally, but I'd do that on any car and at any torque.

Same front and back, the point about the torque wrench may actually be worth looking at though I guess??No difference between front and back....all same torque?

I certainly do use 130ft/lbs for my other car, but it has alloy wheel nuts unlike the steel nuts on the Cerb.The Cerb Service Manual says 50-55ft/lbs, which is lower than anyone else has mentioned on this thread. I think I'll be checking them regularly if I ever get to drive it again!

That's the trouble these days, plug em in to a bloody computer and have it all done, no skill involved, mutter mutter
Not that i know the official figure but, i'd be pretty sure that the 75ft/lb or 101Nm is more than plenty for the car mate - I've never lost a wheel as yet. In fact i'd even go so far as to say that you could, if you wish, go lower on this setting.
