Got a flat on the daily driver and went to put on the spare. Popped the trunk, ripped out all the crap in there, go to undo the spare and saw this. Pretty sure tires aren't supposed to look like this.
How exactly does this happen to a tire? No date code on the tire so no clue how old it is but the car it's in is a 98. Surprisingly it still had air in it but what caused the failure? Water? Heat? Cold? Age?
