Usually the steel bead tires can be twisted into halves or thirds for shipping without any damage, although I like to store them loose. Now the Schwabe tires are pretty beasty tires, so perhaps it would be difficult to get a tight packing. However, at least with my lighter weight practice tire, twisting it into thirds seems to be the safest. I have kind of "tacoed" my tire, but there are no tight bends.

At least contact the vendor and let them know that they are using improper packing techniques.

I still believe that if you can straighten the bead and mount the tire, you should be fine... perhaps if you get past the first 10 miles..
