[TR] TR3A Wheel info?

TR3 bolt pattern is same as TR6, but it's not 118mm.  4.5" == 114.3mm

Also, the standard TR6 steel wheel is 5.5" wide (measured between the bead seats, which is the standard way to measure wheel width).
They actually fit fairly well on a TR3 as long as you don't go overboard on tire width; but won't fit into the spare tire
compartment.  So I use a TR3 wheel for the spare and if I get a flat, the wide wheel has to ride home behind the seats.

Offset is very important if you want to fit wider wheels on a TR3, though.  The aftermarket 5.5" alloys I tried were just enough
different that my tires wouldn't fit under the fenders.  Unfortunately, I don't know what it is offhand.
