Might be helpful to know what the rim is rather than the tires.

What concerns you is the inside rim width. It isn't critical since each would accept a range of tire widths, so if you don't want to remove the tire first, you can measure the outside diameter and subtract 5mm to allow for the wall thickness. This isn't precise, but is plenty accurate enough for your purposes, or as we say "good enough for government work"

Granted the pressures are lower but that's due to the terrain more than the tire limitations on the rim.

Hi,

The real question is why do you want thinner tyres and what tyres do you
currently have, and why do you think thinner tyres will help matters at all.
