Subject: [uuc] Re: TRX Wheel Question
Hi Keith, back around 1980 or so, Michelin was trying to invent a better
wheel/tire combination. They decided that the bead angle (the angle of the
wheel lip where the bead mounts) should be 60 degrees instead of 90. Since this
was incompatible with everyone else's tires, they came up with their own wheels
in metric sizes. For example, the wheels on the 5-, 6- and 7-series of the mid-
to late '80s are 390 mm x 165 mm, which translates into 15.4 inches in diameter
and 6.5 inches wide. This makes it pretty much impossible to mount a
conventional 15 inch or 16 inch tire on a TRX wheel. Michelin sold these as OEM
to several car manufacturers, including BMW and Ford (Mustang, Capri)."
