Confirming specific tires approved for use in the United States.

Q: We are getting Continental HDU-1, 385/55R22.5 tires on some new articulated buses made in Canada. We understand that Goodyear and Michelin make a similar size tire but we cannot find anywhere that these tires have been approved for use in the United States.

A: Goodyear markets tires all over the world and different markets often require different size tires.   In this case, we imported tires from Europe to fill the need of a particular customer.   These tires are not readily available in the US market but, they are approved for the US market.
