TR2/3/3A TR3 wheel specs?

[karls59tr]

Anyone have a link to Tr3 wheel specs ie. Distance from bolt hole to bolt hole?...Is this called bolt hole diameter and measured across the center hole? the offset? are TR6 wheels the same? Will 5.5" wheels fit the "3" without spacers? thx Karl

It's typically called BCD -- bolt circle diameter or PCD -- pitch circle diameter, and it's 4.5" on the big TR wheels.

5.5" rims can fit, but it is all about the offset or backspacing on the rim.

In addition to the above, some wheels can interfere with the brake calipers.

But stock TR6 wheels fit pretty good if you don't go too far on tire size.
