so you need to wear a touch off before trials cause you go up a class over 36"

depends on the air pressure & rim width when measuring but they are give or take abit around 36"

Rolling diameter isn't affected by air pressure. even if the tyres are flat, it will still have the same rolling diameterdepends on the air pressure & rim width when measuring but they are give or take abit around 36"

If they only have 5psi in the & bag up, the distance betwwen the centre of the wheel & the ground will be less than if you have 45psi in them & square shoulders on the side wall.
If you change the distance between the centre of the wheel & the ground you will effect the rolling diameter.

Diameter changes with lower pressure but rolling circumference is fixed at the tire size.
