maybe you misunderstood. I measured with a photogate. Hence the "it's a lot easier to measure"

I'm pretty sure I'm not the one struggling to understand the physics involved

That's a great and all, but why is it that race teams have been putting larger diameter rims on races cars, and every decade they seem to get just little bigger?

brakes.

Enough with the nerd talk, I think you guys need to race.

I was hoping for mud-wrestling.

If there's a race to be done I pick my home turf in eastern UT:

But, back on-topic as this is tech and not OT.

Getting back on topic - this really is the mitigating tradeoff. Smaller wheel diameter is generally going to be better for a number of reasons we've already beat to death, but at the end of the day you have to fit brakes. You need brakes big enough to do the job, and then the smallest wheels you can fit over those brakes. If there's a big gap between your front rotors and the inside of the front wheels, you're not being optimal
