Slaughter Grid has been my go-to rear tire for a while on the trail bike now, but I had a weird thing happen to one the other day. Landed a hip jump fairly cleanly (I thought, at least). Tire burped, made a horrible sound, and as I rode out the landing the tire was rubbing on the frame. "Shit." I thought, I've trashed the wheel. Nope. Rim is straight. No sign of any tire damage, and the bead is sat evenly around the rim. Somehow, the carcass of the tire itself had gotten distorted. Deflating and resetting didn't solve the problem. No sign of any damage on the outside of the tire, just a weirdly shaped tire.
If you roll the tire and look down the centerline is it like a wobble that you'd see from the bead not seated in one section?
I had one like that and just figured I was an idiot and didn't notice it when I first put it on. But yeah it's like the casing on one side stretched or something. I just wrote it off as a screwy molding but it was bad enough that it seems odd I wouldn't have seen it when it was new and popping the bead on the first time. Same tire, slaughter grid.
