What wheel bolt torque setting? 2001 Sterling Eccles Onyx

[EcclesAsh]

As per the title, does anyone know what the wheel bolts on my 2001 Sterling Eccles Onyx should be torqued to?
I don't have a handbook and can't find any specific info on the web.
The caravan has 14in alloy wheels.
Thanks in advance!

Alloys will always be higher torque than steel wheels, and I can only guess that you will be between 100-120 nM. My own Sterling is 130nM but not same age or model.

You could always ring Swift Customer Servives or Technical Services on Monday morning.

Alloy: 120nM
Steel: 88nM

Check first they are M12 bolts. If mine, where possibly I don't know if the wheels are original, I would check to make sure it had at least 10.9 rather than 8.8 grade bolts, and torque up to 130 Nm.

The bolt grade ought to be moulded on the top of the head, visibly.

They must be at least 10.9 Grade to use at this value; also if they are not, then there is every chance along the way in the past they have already been over torqued.
