Bias Ply tire options for 1969 Camaro

[x33rs]

Any word on the front tires?

I might take the plunge this weekend and order a set, and check the back spacing a couple different ways. If it turns out they won't fit the Camaro, I'll put them on another car here.

Incidentally I was searching around and found that Weld Wheels measures the backspacing just how I originally described. Video here, fast forward to 3 minutes and skip the mumbo jumbo.

Has me thinking.....how is American Racing doing it? Because Weld is doing it from the very back lip of the wheel, like I mentioned earlier. I believe that is the standardized way. Measuring from the bead set gives me the confidence that the wheel is the same as a 15x7 rally (~3.75" from the bead), but what are they doing?

This is how I've always understood backspacing as well. If you find American is doing it different, please post back, as I've ignored some AR wheels duw to lack of backspace.

If you compare the backspace and offset listed in the AR catalog for a given wheel, I believe they are doing it the standard way (same as Weld).
