Is there a good estimate of the thickness of the aluminium on Alcoa forged aluminium semi wheels 22.5 type. Figures need not be precise, or just a range, for estimates, is 1/2 an inch a good estimate for the thickness of the metal on an Alcoa type forged aluminium wheel? Thanks in anticipation.

    Whereabouts are you taking the measurements? Hub face, rim, spokes...

  • As they have a kind of taper to the aluminium plate, ie the pictures show they have a different thickness from the part near the wheel rim to the part where near the bolt area. So, any info about thickness near the Bolt area to near the rim is helpful! I could then average the two get a kind of estimate! Or just any estimate of thickness whether near bolt area, or Rim!

A standard 22.5" x 8.25" Alcoa wheel (p/n 88367x) has a disc thickness of .875" which is about double the thickness of a steel wheel.
