regarding torque, what most people don't realize is that the maximum value is at least as important as the minimum value. And I am not talking about something obvious like breaking or stripping a fastener right away. Here's why:
if you overtorque a fastener, the stud will be overstretched. When that happens, the material can fatigue over time and permanently stretch, causing your fastener to then become UNDER torqued, and come loose. When using a lubricant like anti-seize compound, be sure to REDUCE the max torque value by about 15%, since the lube will allow you to input more torque than you should.
On something as important as a lug nut, especially on a mini who's parts were designed for a pretty low torque value (most cars use twice the amount, at something like 80 Ft Lb), use a torque wrench to do it right.
Maybe all that will go wrong is you'll break a stud, or maybe you'll find a wheel is loose after a few thousand miles, or maybe, worst case scenario, a wheel will fall off.
Please, just use a torque wrench, and do it right.
thx,
Norm "instructions reader" Kerr

I remember tightening the lugnuts on my '71 up to 80 ft/lbs. Hahaha... well, one at least until it snapped off. Even I realized that was just a wee bit too much then.

Others above have provided the values. Along the lines of Mark's first comment... "German Tight" (a.k.a. goodentight). I seldom use a torque wrench on wheels. Doug L.

And check your torque frequently. I was surprised that it took 4 rechecks over several days for some of the nuts to keep torque. dan "I don't know much, but what I do know I know little of "

I really don't think its some thing to stress over. Maybe I'm lucky I haven't snapped a stud or lost a wheel in 40 years. Tight is good but don't go overboard...
Cheers, Ian

Torque is for the stud. Same stud? Same torque.

according to Rover, it is the same for alloys as it is for steelies, 60Nm, or 40 ~ 43Ft Lbs.

45 ft/lbs is what I've used. I believe that's what the manuals call for.

Greetings All! Bought some new tires for the Mini Countryman, just wondering what the correct torque is for the lug nuts on a standard wheel. I'm having them mounted and balanced today. Thanks! Mini Estate "It's a good day when you wake up with a Woody!"
