"I will NOT buy fat tyres . . . . ."
What's the point of refusing to adapt to conditions? Unless you're a community activist determined to improve the infrastructure -- and find mutually agreeable ways to fund it -- the conditions will not adapt to you.
Get some tires that offer a reasonable compromise between speed and comfort.
Then go run for public office, become a news media magnate, and change the world. Or your little chunk of it.
