Is there a way to estimate contact patch size given tire size plus tire volume and rider weight?
Specifically, I've tried to build a unicycle that maximizes contact patch for riding on soft snow. I have a 26"x3.7" tire with a 65mm rim that I have at 12psi, how can I calculate the resulting contact patch?
For extra credit, I'd like to calculate the contact patch size required to ride across newly fallen snow for a particular rider weight.
This question was previously asked as a comment on my previous question, but I feel it needs its own question...
