Product Information

I've had a couple of torque wrenches. Draper beam type, so not very decent, but still too decent for wheel nuts, which I never ever use a torque wrench on.

A document from AOR Campers online suggests its literally somewhere between those two figures, which seems ludicrous to me. I hate vague information, and you can’t get more vague than that; somewhere between 135 and 200nM! You need to know what the wheel manufacturer recommends as its torque setting for wheel nuts Steel vs alloy wheels OTOH, and to add a bit more complication, I occaisionlly treat the hubs with sunflower oil and aluminium, which will start out slippery but turns into a fairly strong glue. Perhaps I should sprinkle it with fine sand to micro-stake the surfaces together until the oil sets. Torque wrenches allow you to measure and limit the amount of force applied to a fixing. Every nut and bolt in your car will have a torque value. It’s particularly important that you have a torque wrench to hand if you’re working on the engine, gearbox or any crucial components in the drivetrain or suspension system.This is a good habit to get into, particularly after your car’s wheels have been removed and refitted. Grit can get trapped between wheel nuts and the facings where they ‘seat’ on wheels, potentially creating false torque readings that aren’t indicative of actual clamping force.

So if I understand you correctly, friction between the hub and wheel surface prevents excessive sheer loading of the studs, and a suitably high tension on the studs keeps that friction adequate.Wheel nuts that are too loose can cause a wheel to start wobbling as it rotates, creating noises and vibrations which can be easily detected and usually cured by stopping and tightening them. However, if they have been over-tightened, it can create more headaches than just being stranded on the roadside. Damage caused by over-tightening What torque do you do your caravan wheels to? Does it match the wheel, and hub manufacturers recommendations? We torque our Reconn R2 wheel nuts to 160nM This can cause stripped threads on wheel nuts and wheel studs plus stretching of the studs, which makes them weaker and prone to fracturing and eventual failure. This stretching can also cause the wheel nuts to work loose.

I did more research, and found that the torque specifications often come from the wheel manufacturer. Many alloy wheels on big, off road caravans are recommended to have their wheel nuts torqued to 135nM. So, do you do it to 135, or somewhere between that and 200, or the full 200nM? I’ve had my Teng wrench for a few years now. It gets calibrated every year, and I’ve never had a problem. It’s not an ornament. It’s used heavily but still performs and looks good. I’m happy to recommend it. It’s a good kit.

Is it the same thing as a tyre iron?

The only solution then is to remove the dress-cap with a chisel to access the wheel nut, which not only destroys the dress-cap but also increases the risk of alloy wheel damage while doing so. How to avoid over-tightening the idea is use the bolts or nut/stud to compress the wheel to the hub, so the whole lot takes the weight of the car, not just the nut/stud bolts so its not as simple as you think The point is the wheel studs or bolts are being used as sheer bolts, if, assuming as some do put grease between the wheel and the hub, the hub point is meant to be a friction coupling (had to look this up to confirm) I clean mine every use and store it on a shelf where I can grab it real fast. Come winter. I’ll spray it with WD40 and keep it in its hard case to keep moisture off it. You may want to store yours in the trunk. If so, store it securely. Why? Because if you fail to adequately torque a bolt, it could work its way loose. Or, if you tighten it too much, you could cause costly damage. About torque wrenches from Halfords

On our Reconn R2, I’ve been doing the 6 studs up to 160nM, as this was a figure we were told by a Caravan place a long time ago, but perhaps its marginally too high. With Steel wheels I’m less concerned about damaging them, and more concerned about not having nuts come loose!Of course, strictly speaking (which is really the way one should speak about this kind of stuff) grease doesn't alter the torque put on the threads. this is why any type of grease on the hub or threads is not advised, as the grease can allow wheel sheer movement.
