I've seen some discussion here and there but no solid answers yet, and I don't know much about tires. Do we know for sure whether or not we'll be able to put bigger tires on the Trailhawk? I haven't seen one in person but in photos they still look a little small to me so I'm just curious. ANY bigger is fine by me, I'm just wondering what it might allow, even if it's only a small difference. Just to toughen it up a bit more. Thanks!
