Why so many blowouts?
I see a lot of posts on this site about blowouts... Is it due to extreme heat? Exposure to sun? Speed? Low tire pressure? A combination? The majority of posts seem to be from southern areas where i...

There's also the possibility of over-inflation being the cause. So many people seem to think that the "correct" inflation pressure is the number molded into the text on the side of the tire, regardless of the actual load being carried, rather than getting their rig 4-corner weighed and inflating to the manufacturer's recommendation.
Over-inflation results in the tire having a curved profile at the road surface, with the center of the tread taking more of the load.
Also, the term "blow out" suggests an explosive failure, not a simple loss of pressure.
The pressure listed on the sidewall is the maximum cold inflation pressure. That's the psi at which the tire will hold its maximum weight rating. A healthy tire should never fail when inflated to that pressure. If a vehicle is at or near that weight, then that's the pressure that should be used for inflation.
