Fender/ tire clearance. How much is enough?

Road bike with 32mm smooth Gravelkings. Iíve got 13,maybe 14 mm between the tire and the Paul Racer M brake. But this is under tension. If I release the cable to install an inflated wheel/ tire, itís down to about 10mm. But in normal operation thereís 14mm clearance.

Is that enough to safely run a fender?

In front thereís 12mm at the front of the fork and a few more at the rear, but it has a disk brake. Is this enough room?

And then, how about with a tire with small knobs like the Gravelking SK?

Iíll likely be using SKS Longboards which are about 3mm thick. That leaves 10 mm actual clearance.

Sounds like very tight fit. But there is only one for sure way to tell is to (try) install the fenders.

After install your tire/fender clearance will be even less than what you measured. If your taking your gravel kings off road, gravel or mud could easily wedge between the tight clearances.

It sounds like a NO GO to me.
