At least that's what Mark Krolh said.

I don't doubt what you are saying yet my Montana HC 370BR arrived with Rainier tires on and 7000# Dexter axels. The wheels and valve stems are exactly the same as those on Montana units. Weight and cost are still a priority.
I switched to Sailun S637 with less than 45 miles after purchase.
