MG Midget and Sprite Technical - Torque for Minator alloy wheels ?

Ladies & Gents
I am about to fit a set of Minator alloy wheels and was wondering what torque setting people have found suitable (or not suitable) for these type of wheels ??

I purchased two new rims from MWS but they will not reccomend a torque setting. (+ a set of the suposedly correct wheel nuts)

Yesterday I fitted them using 40ftlbs which felt good. Any comments suggestions welcome.

Ehhhh tight
Never striped a thread but i did lose a wheel once because of UNDER tightening the nuts!
So i just make sure they are tight

Onno, you need to eat more wheatabix!

You can most definitely strip threads and shear wheel studs by over-tightening. Handbook says to do them to 45 Ft lbs although I do mine to 55 without problems. And although you are asking about alloys, it is the stud size that determines how tight you can go.

It is not uncommon in the States - where I understand everything is on a bigger scale - to replace the standard 3/8" studs with 7/16" ones - or maybe larger.

As Guy said the owners Handbook (such a useful publication) says 45 lbft

And I'd recommend sticking to that

I've had to replace a wheel stud on my previous Spridget because a tyre fitted went to the standard 65/70

I've also had to replace a wheel stud on my present midget with Minatur wheels despite always telling places not to go above 45

At 45 I've never had any (of the 16) wheel nut come loose in many tens of thousands of miles in my Spridgets

Pinged plenty of studs in the past ---If you are going to drive angry ----
1/2" studs - 90 ft/lb

I busted a wheelstud when tightening just one hour before taking of for the ferry to the UK last summerholliday.
Needles to say I missed the boat... ;)


Ive always done it on feeling and not on torque settings, maybe thats why it broke? :)

45 is very is easy to go pass by hand when you're big and butch or fat and heavy like me

you'd never do 90 on the standard Spridget wheel nuts and always get away with it in my experience

Broke a few on my mini and remembering what a bloody rotten job it was to replace them i stoped pushing so hard.
Now i tighten them and check the 1st time i fuel up after.

Thanks for the comments guys.
I 'll stick with my 40lbs sounds like thats in the ballpark, I tend to have them lower than normal because I always lubricate thread and seats.

I use 40 ft/lbs on my race car - never had a problem...

Some people use bigger (1/2" UNF studs) as Willy says so you can use heavier torque settings...
James Bilsland

I was told to torque to 45ft.lbs (61Nm) when I bought mine back in 1998 and I've stuck to it since then with absolutely no problems - so far!
