How much tread do you require? I should still have a couple Firehawk Run Flats I got from another forum member. I could measure up the tread depth if you're looking to replace your tires and need something in a hurry for the meantime. Unfortunately I am not planning any trips to Edmonton otherwise I would bring them out! (I just need to make sure they are still around, things got cleaned up while I was away on my honeymoon).
