I'm wondering if the super single tires on a tandem axel expediter truck would qualify ,in the south , to use the 6 wheel or less lanes. That could be an advantage to those with the super single tandems that they would not have if they had 10 tires on the truck. It would not help in california as their speed limit is 55 for 3 axels or more, 70 for 2 axels. Have not heard anything about this and was wondering if any one knew conclusively?
