I'm not sure I'd drive through the pits on that tire, let alone down the track, that's a mighty rough looking skin on the front one. Especially the loose skin that is hanging over the side and the big split in the top of the hide!
Could be camera angle or bad lighting...
Couple of questions come to mind: what tire is that? I don't remember hearing or reading about a GY tire rated to 400+? Also, it doesn't look like there is much room for growth between the two tires, any idea how much clearance for tire growth there is between them? The info I have on the MT 25.5 is that they grow 15% at speed, does this hold true for these GY tires? Also, what size are they, they look to be a rather small diameter?
