Curbing trailer tires...

I think the sidewalls are much more susceptible to damage than the tread part, if you look at one of those cutaway diagrams

 

See now if you used the outside turn lane, you could avoid all that trouble

 

Absolutely.

 

I used to deliver retail stores in NYC and Boston...had a Sterling single axle day cab I was really fond of. Reason being, it rode a lot higher than the Internationals or Freightliners, and I could drive over more curbs with less fear of bending hard parts. If you're gonna roll a curb, do your best to take the curb at 90 degrees to the tread, and just roll slowly over. Sharp angles or scrubbing sidewalls can be instant tire death if you didn't see a bit of angle iron poking out of the curbing (NJ-17 just north of I-80, on one or more of the little bridges near the Sears(?) warehouse, for example).
