#2FTA: Can we verify the folklore that on a long bike trip the back-tire wear is less than that of the front tire?
I’ve never heard that folklore. I thought ‘everybody’ knew back-tires wear out a lot faster because the load on them is higher and because they’re the one being powered. https://www.sheldonbrown.com/tire-rotation.html:
“It is common for a front tire to outlast a rear tire by as much as three to one. Rear tires have more weight on them, and also have to deal with drive forces.”

Yeah - that just seemed completely wrong based on my experience. I've commuted by bike for years, and my back tyre is always the first to go.

From my experience, front tires only wear of age, not use. Backtires experience (frictional) shear forces, pushing along the earth. This erodes the surface.

At €70 a pop, my tyres get rotated front to back, as required.
Back wears out much faster.

#6The math and physics and engineering behind bicycles is so cool. Such a "simple" device, but so many interesting things to dive into. I wrote my thesis on spoke patterns for the wheels [0]. Another cool thing is how the steering of a bicycle works. You don't really turn the way you want to, you actually turn the other way first to initiate so the bike moves from under you, and you then lean the other way to actually turn. This is why, if you're for instance biking close to a curb and want to get away from it, you really can't and it feels like the curb is "sucking" you closer and closer. Since it "feels" wrong to first turn towards it, but without doing that you actually can't get away from it.

Same. Also same on my road bike, which I bike in a very different manner (not as much stop&go, short turns etc). And I even do most of my breaking using the lever connected to the front tire.

70€ for 15k kilometers or so is really cheap. It's incredible how cheap cycling is per kilometer. At least an order of magnitude cheaper than driving.

#9Where else would the department of theoretical physics engage itself in modeling bicycle tires than in the Netherlands?

Somebody had to advance Feynman's work on spinning plates.
How on earth science.uva.nl was inspired to pair up plates, add some thickness and a drive chain will likely remain a mystery for the ages.
