Dirt to pavement transition

It really helps if you include the context you find stuff in. I had to google those terms to be sure you were talking about racing.

"Dirt to pavement transition", with ideal punctuation, would be "dirt-to-pavement transition". It means the transition from dirt to pavement - the place where the road changes from dirt to pavement.

"Dirt chicane to dirt jump" indicates that the racers will move from a chicane (a tight sequence of corners in alternate directions) that is dirt rather than pavement or gravel to a jump (a place where the ground rises and then falls away sharply enough that the racer is in the air briefly before touching ground again.

I can't say about "hard tier". Where did you find it? Are you sure that wasn't a typo?

Thanks Eos, you've googled the right context.

Regarding "hard tier"[sic], it was from New York Times.
