Muddy Tires is a close-up cycling challenge that asks you to photograph muddy tyres, a muddy frame or other clear mud on the bicycle. The bike itself carries the proof, so the mud needs to be genuinely visible rather than implied by the surrounding path.

This quest reverses the usual polished-bike photograph. Texture, splashes and the line of the tyre are the details worth preserving.
Finish a ride with visible mud on the tyres, frame or another part of the bicycle and document it.
Show clear mud on the bike itself. A muddy trail with a clean bicycle would not satisfy the current wording.
Upload one photo focused closely enough to make the dirt unmistakable while retaining the shape of the relevant bicycle part.
Keep hands and clothing away from moving parts, stabilise the bicycle before the close-up and clean braking or contact surfaces as appropriate before another ride.
Let the bicycle show where it has been and capture the dirt before cleaning it away.
