Scientists replaced 40 percent of cement with rice husk cinder, limestone crushing waste, and silica sand, giving concrete a rubber-like quality, six to nine times more crack-resistant than regular concrete. It self-seals, replaces cement with plentiful waste products, and should be cheaper to use.

Why would tire lobbyists be stopping the material used on the road?

I think there’s enough people who don’t know you have to rotate your tires to where they don’t need to worry about the road conditions.

Our tax dollars are supposed to be used for upkeeping the roads, which doesn’t happen near me and I would be furious if someone was lobbying to keep that from happening.

Edit: found one.

Differences in camber front to back, toe in out or neutral, weight differences etc all can cause wear bias. Rotation of tires allows for even distribution of said wear on all 4 tires. Saves you money/tires if you rotate often. Heck, you can do it yourself easily too.
