FYI

8.5" +34 does not equal 8" +34 or 9" +34, etc.

You can only do "quick math" if the width is the same.
Ie: 8.5 +34 vs 8.5 +44 = 10mm difference

If width changes your numbers comparing do as well.

1" = 25.4 mm (call it 25mm)

8" +34 vs 8.5" +34 is 12.5 mm difference in width
So, 6mm more wheel in, 6mm more wheel out.

8" +34 vs 9"+34 is 25mm difference in width
So, 12.5mm more wheel in, 12.5mm more wheel out

Then of course any mm difference in offset.


Lower offset number, more wheel poke
Higher offset number, less wheel poke

Any other questions, ask away.


I'd prefer to teach you how to fish than just give you fish to eat. This way you can teach others if you choose to.
