Steel and Alloy Wheel Torque settings please (1 Viewer)

[Bollard]

Any Funsters out there know (1) Torque settings for Fiat Ducato 2010 maxi 16" Steel wheel spare and torque for the existing alloy wheels? Are they the same? If I have to change the wheel in case of a puncture (2) are the studs bolts the same. Any advice would be appreciated rather than scratching my head at the roadside!!

I bet when you go to remove a wheel they are TAF

16" steel is 180nm
I don't know about alloys
I manage to undo mine with the standard fiat toolkit no problem

Wheel nut Torque is governed by stud size NOT wheel size or materialoh:
M14 studs or bolts 140 Nm
M16 studs or bolts 180 Nm

wheel nut/stud tapers can be different between alloy and steel wheels as can the length.....alloys being a far thicker wheel centre than steel and nuts generally being of the 'blind' variety.

I learnt the expensive way with locking wheel nuts.......
Took off the alloy to fit the steel spare.
Tightened the wheel then removed the locking socket....and the end of the locking wheel nut.

The nut would have been fully tightened maybe 15mm before it actually touched the wheel so it cracked the alloy nut around the end and pushed the end off.

It's fair enough to call it 15" and 16" wheels in relation to X250's i.e 14mm and 16mm bolts
but the correct torques are........ 160nm for 14mm/15" 180nm for 16mm/16"

Our van has alloy wheels fitted, but the spare is steel but in the Jack / wheel brace box is a spacer to use with the spare that make it the same thickness as alloy and use the same bolts. Bob.

I must be doing something wrong ! As I’ve never used a torque wrench for wheel nuts in my life

You went to the trouble of typing a long reply then realised the thread is 5 years old... Didn't you, go on... DIDN'T YOU?

Yes you are.
There's a torque wrench setting for a reason or none of the vehicle manufacturers would bother with one.

I’m sure your rite BUT they will have tell all the tyre centres/garages as I’ve never seen them using a torque wrench in my 40 years of motoring

I agree, but if you can’t do up a nut or bolt without a torque wrench, you should get a competent person who can.

Most of the air guns they use will stop at the set torque.

They always torque wrench after the air gun, legal requirement in the UK but I've never seen them adjust the setting on it.
I always carry a torque wrench in the van.

So you can tighten a bolt to a precise torque just by feel.
You're unique in the world.

Peter and Lenny beat me to it.

I used to be quite good at guessing 40ft/lb on my Morris Minor but no chance at 180nm on a Ducato.

Not at all, when I was mechanicing for a living the only time a torque wrench was used was for cylinder heads, bigend bolts/nuts etc...after a while you do get a feel when tightening stuff.

If a torque wrench was used on every nut and bolt, you'd never get anywhere.

 

[olley]

Wheel nut torque is just a best guess, how accurate is the torque wrench? Is the stud and nut clean? Is it lubricanted or dry? So many variables.

To be honest for years I just tightened them up with a bar and socket then went for a run and checked them never lost a well in forty years of driving millions of miles driven
But I must be getting soft in my old ade I use a torque wrench now
I only ever used one on head bolts and big end crank case bolts every thing I fixed semd to work OK and not fall apart
