Country,
It varies. We've seen Trail America most often, some Goodyears, I think some Freestars and maybe 1 or 2 other brands.
As an aside, by having Tredit Tire speak at the last rally in Goshen, we learned a lot about the tire industry. That learning does not make any of our tire issues go away but it went a long way to helping many of us understand why it is very difficult for a trailer manufacturer to "specify" only 1 specific tire for their units. Bottom line is, there is not enough capacity within the supply chain for Heartland to specify, for example, Goodyear G614 RST 235/85-R16 for all Landmarks that require load range G tires. I always thought it was that simple - just specify to Tredit and you always get what you want. Does not appear to be possible.
