If the tire you took off is an H rated 16 ply, then it is a light truck tire. If it is a light truck tire, regardless of the number of plies, it has a less stiff sidewall than an ST tire, meaning that the WCC is far lower on that tire. If that is the case, when one tire blew, the other was totally incapable of supporting your load by itself and it too exploded. Please let us know what model Sailun tire you were using.
