There are numerous calculators that will tell you speed at RPM at different tire sizes and ratios.
You are trying to get the balance right between a lot of factors and its not always easy.
You have to start with that judgment call regarding the optimum RPM for your priority usage.
I'm happy to dialog at depth about this, but today have run out of steam. Keep the dialog going.

It's true. I really don't do anything but browse the Internet looking for trouble... | | |
