I would like to think that stress-wise the tire would be fine. I've put it around NJMP's "Lightning" track and it's had no trouble at 100+ mph. To me, it looks like the crack is right where the rubber is thickest. I'm assuming that's there to protect the rim, but I'd still hate to drive 3.5 hours just to fail tech
