Purchased in the Czech Republic in the summer of 1905. "thrown away" on April 22nd, in light of one "of"'s seasonal shoe replacement ritual. internal steel cord. I have no concerns about the tires. After 36 hours on the road and nearing the hydroplane indicator, I was ready to head south and "scheduledly" abandon the vehicle. However, I noticed that thread and chose not to risk it because life is more costly.
