Our present van has 15 inch aluminum wheels held on with 6 x 12 mm studs (single axle) . Just wondering if any body can tell me
how much toque the wheel nuts require. Never used a toque wrench on wheel nuts in my life with no problems until the last couple of years
when I have had one stud fail on the Landy and all six at once on the caravan causing the loss of a wheel. Starting to get a bit paranoid so bought a
new toque wrench just for the caravan.
Landy

130 n.m. for 12m.m. stud, or check your van manual.

Dry, clean, unlubricated.
Cheers,
Peter

I have black alloy wheels on my Jayco, six studs per wheel. Its handbook states 150Nm for the wheel nuts.
Label on the van states to retighten the nuts after 100km.

My Landcruiser has 14mm wheel studs and the manual states torque value of 130Nm, so 12mm would be less than this.

Thanks everybody, I had another rake through the vans paperwork this afternoon I could not find it in the caravan hand book but turned up a folder from the axle manufacturer Dexter, they are recommending 120 foot pound which sounds a bit high to me, I have heard aluminum wheels are supposed to be tightened more than steel rims but that seems like a hell of a lot.
Landy

That 120 foot pound looks correct to me. Just don't get confused by unit references.
Same as watsea above, my single axle Jayco's manual (6 studded alloy wheels) states, "150Nm" = "110 foot/pounds".

My van has 12mm studs which are the same size as my Ranger so I tightened both to Fords recommended torque setting which is 135nm or 100ft lbs. Both have alloy wheels. This is dry torque without lube. If you lube the studs the torque figure needs to be reduced otherwise you will end up with stretching your studs. Vehicle manufacturers quote in either lubed or dry torque numbers. Lubing wheel studs is an old idea that you rarely see in modern car manuals these days. The last car I owned that quoted lubed torque figures for wheel nuts was a 69 Triumph. The cause of many stud failures is over tightening, so be wary of doing so. I have never had a stud fail or a wheel come loose from a correctly torqued set of nuts.

Thanks again everybody. The Landy ( steeel wheels )is recommended 95 foot pounds and the studs are about 14 mm (probably not metric ) and I never lube wheel studs. I will probably go 115 foot pounds 155 nm meters on the caravan As I'm still not happy with the recommended 120 foot pound from Dexter
the trailer repair place that I took the hub and broken of studs and nuts to said they could tell that it wasn't due to the wheel coming loose so had probably been over tightened. I will see how it feels when I am pulling them up.

As I mentioned in an earlier post, do not forget to re-tension after 100km.  Alloy wheels can come loose.  My experience was this.

Wheel studs were still there.  Wheel and nuts gone. A three wheeler for a while

In my case it was a one wheeler for a while

Haha, I just went over to the Storage where our Van is to check on tyre size and to make sure the wheel nuts fit another set of mags that I might use. Couldn't get the nuts off with a wheel brace. Guessing they've never been off since new (2020).
