Hi all, going to be fitting some winter wheels (nice ones off a top bloke, forum member) 18" to my F15 3.0D sport this weekend with help from my friend who is a mechanic. He has asked me to find out what size the wheels nuts/bolts are and what torque you tighten them up to please. I checked nuts/bolts size which is 17 but no idea on torque ?? guess its ok to use the ones coming off my 20" staggered set up is ok for the 18" non staggered.
Thanks in advance

i torque my wheelnuts upto 160nm on my e53

Mark,

I found what purports to be a definitive answer that states 140 nm but it then goes on to quote the tyre pressures incorrectly (35 PSI) so I’d err on the cautious side and try and blag the values off a friendly dealer if they’re not in the handbook.

Cheers,

Rob.

140Nm+/-10Nm is the stated limit in the BMW Technical Instructions..

Overtightening can either stretch the bolts or damage (crack) the holes in the alloys.

Yep, 140 Nm

I do 140 Nm for the studs but 130Nm for the locking wheel nut so they don't get seized on.

Excellent point. It was an expensive "repair" to get those off !!

I actually torqued mine up properly to 140nm this week myself at the tyre shop after the tyre fitters put them on with an airgun last time and I could barely get them off and thought my extending wrench had split the socket in 2 such was the crack it gave when they undid and they were only on a month or so so not seized on.The locking nuts always get less as they are easily damaged if they are on /off too often .

i stand corrected and will be redoing my nuts at the weekend to 140 nm , just looked in my handbook and it to says 140 nm

thanks all 140 it is and great tip gmc15 for locking wheel nut, most appreciated

Had that a couple of times in the past and place I use now only used a torque wrench the finalise and a low power electric gun to do the first bit.

Rear wheel nut torque setting thanks.

You learn something new every day - even at my age! I've habitually been using 100Nm on alloys since God were a lad.

well well well, where did winter go lol.... just had to come back on here to check torque settings as summers going back on 2mo

For the first time in 8 years I didn’t even fit mine as the weather ‘dahn sarff’ did not get bad enough to ever need them - unlike the previous year!
