Steer tires wear

[kryten]

This video from Bridgestone explains concentric mounting.






This one from Michelin talks about runout and match mounting.





This one from Accuride goes over a bit from the other two but it shows the proper way to install the wheel and tire assembly on the truck. Skip to the 22:00 mark for the hub pilot install procedures.





Note on the Accuride video for the wheel install the hub pads or ears MUST be at the 12 o'clock position for proper install.

A few years ago I got a set of those tru balance things and found they weren't worth the electricity the computer used to find out about them. When it came I decided to try them out on a steer tire so before removing the wheel I slipped a feeler gauge in the bottom gap between the wheel center and the hub pad and had a gap of about 0.010". Wheel was mounted using the above procedures. If I remember right the difference between the wheel hole and the outside diameter of the tru balance thing was about 0.025". The theory is the wheel will "hang" on the centering sleeves while you tighten some nuts to hold the wheel in place then you remove the sleeves and install the nuts. If you mount your wheels PROPERLY the tru balance sleeves are loose in the wheel hole so are not doing anything except draining your wallet. They are a total and complete waste of money.
