Anyone know the torque specs for the tpm sensors? And while I am at it the wheels?

Torque Specifications:

Lug/Wheel nuts - (24mm hex) 81 ft/lbs
Oil Filter - 14Nm (10.3 ft/lbs)
Oil Sump nut (Drain Plug) - 65Nm (48 ft-lb)

Don't have anything for TPMS but I believe it was in one of the wheel swap threads somewhere.

I found this on the Hanco site...

On vehicles with tire pressure sensors within the wheel, sensor nut and valve cores must be torqued to specified inch pounds.

Cores must be at 0.13 - 0.27 ft. lbs. (0.17-0.37 N.m).

Found other sites that specified 1/4" Inch Pound for the correct torque

Thank you for the help. I read thru posts and cube states 8nm .tire rack told me 4nm which translates to 35.4 inch pounds.I did not mount the tires yet.but good news I found a cheap source of tpm sensors. It was confirmed by Tire Rack but since I have yet to mount them can't personally confirm it.

oh the source is cheaper than tirerack.
