wheel math ?

I'm working on a steering stability problem in long sweeping corners

[merv]

Ah so!! So you checked swing arm bushes and all the usual suspects?

Its a mathematical problem not a mechanical one

The Krappisaki is too reliable to be defective (and I am too cheap to fix it anyhow )

Tom french tire technology 1989 .... The name is derived from attire -a protective covering or coat; in this sense the american spelling tire is closer to the original than the british tyre ( a tire is still called a cover in the rubber industry )

That was from the gold wing owners club ..which as you are aware, is a much more useful reference than the oxford ..

It is common to find that many american spellings are archaic english spellings.
Aluminum,for instance.

You still haven't told us why do you need this outside tyre height?

The only other way is find someone with a huge caliper set that will fit from the outer edge of the tyre at the top to the diagonally opposite edge at the bottom. Any other means except measuring circumference like most of us described will be a problem e.g. what use is a tape measure trying to measure around corners to get to the tyre edge?

What corners?

[R1madness]

The answer is measure the diameter at the point you wish to know the circumfrence and multiply it by pi. or c=pi x d.
You only need a ruler and a calculator.
