I have none; don't know if anyone else does or not, but, I do know they aren't the more popular, reliable tire brands that I've heard of. Another concern to me, unlike Carlisle, Maxxis, Sailun, or Goodyear, you cannot pull up a thing about Mastertrack tire company. Even the importer, Unicorn Tire sales does/will not speak to the manufacturer that I could find - a bad sign to me.

You might note the names of the tires these guys import....I've never heard of any of them.
