That's an option. Might be the best option cause I don't use wheelbarrows much. I'll look around, and do that, or perhaps buy a tube to put in my tubeless tire.Solid wheelbarrow tires, learn to love them. They're kind of hard to love as they ain't as good as a properly inflated tire but they don't go flat.
I hate spirals. I don't completely understand them, and haven't made the time to cause I seldom run into them. They were popular on highways from the 50s-60s, cause engineers get bored, and want to use all the math they learned in school. I suspect they fell out of favor due to the hospital bills from surveyors kicking down their doors, and beating the shit out them :^DThey should keep the spiral curve. They are great for reducing speeding infractions.
My limited understanding is that they are supposed to get rid of the "jerk" as you enter a turn. That said, as a geographer, all roads are just a bunch of dots connected by as many small straight segments as the analyst felt like digitizing that day.I hate spirals.

They still have a good application on railroads, but I don't do much rail work. For basic layout, I have software that'll do spirals, but they still make everything harder than it should be.
I-75 just south of Cincinnati used to have glorious spiral curve. The spiral tightened northbound as the road descended a big-ass hill down to the Ohio River. Giant blinking signs were not enough. So many trucks rolled over that the state DOT eventually rebuilt the road to take out the curve.My limited understanding is that they are supposed to get rid of the "jerk" as you enter a turn.

Yup. On road applications a simple compound curve is more than sufficient, and easier to compute. You could probably get away with compound curves on railways, but I suspect the stacked curves would get more complicated than doing a spiral, especially with the fancy spurs they use entering industrial areas.My limited understanding is that they are supposed to get rid of the "jerk" as you enter a turn.
