Real world tyre diameters to determine gear ratios.

I’m looking to buy a new bike in the near future and I’m thinking of going for a bike with 27.5”.
However, since I’m basing my experience on past and current 26” bikes with knobbles and slicks I want to work out what gear ratios I need to select to match current and past bikes.
Therefore, if anyone out there has the following 27.5” tyres and would be kind enough to do some real world ‘tape measure’ measurements of the circumferences it would be greatly appreciated.

Continental Mountain King II 2.2” and 2.4”
Schwalbe Hans Dampf Evo Snakeskin 2.35”
Schwalbe Hans Nobby Nic Snakeskin 2.35”

Cheers,
Tom.

    Close enough that as part of changing to another bike you won't really notice a difference. HTH.
  • I dare say, but I'm still curious and I like to crunch the numbers.
