If you mean the the nuts that retain the hubs & bearings you don't tighten them in the conventional way.
Procedure is tighten the nut up (medium tight say 35 ftLbs) and spin the wheel by hand to settle the bearings then slacken off the nut,
re-tighten gently until it is just making full metal contact(say about 15 ftlb) then slacken the nut back by about 2 flats, usually at this
point you can turn the nut with your fingers.
Now spin the wheel and check it spins freely and there is a very tiny ammount of free play/end float. You may have to adjust the free play by
slackening or tightening the nut one or two flats of the nut to get it right, it isn't a precise science but some end float/free movement
is essential to allow allow for thermal expansion

From Haynes manual
tighten to 27 lb/ft (3.73 kgf/m) then skacken of 120 degrees (2 nut flats) If that doesn't get rid of the rock or it's noisy replace the
bearings

Brilliant thank you,
have worked on a Mini (85) recently and had to take them off with a scaffold tube so this is very different
