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...

Maybe.
Blowouts are caused by overloading or low inflation, and also by just plain old tires.
Bad luck can play a pretty big role too.
A very good reply.
Low pressure (or high pressure) either one can cause shortened tire life and a blow out. Some folks inflate to one of the following pressures. (note these are examples and yours likely WILL be different)
Molded in the tire is ....... Maximum pressure of 80 PSI
So they go 80 PSI (The full sentence is Maximum load of XXXX at Maximum pressure of 80 PSI)
Some read the sticker inside the RV and it says "Tire pressure 60 PSI" so they blow it up to 60.
Some: Well the tire store always puts in 70 PSI.
A few folks run the RV across a scale twice and go to the tire maker's web site" THis wheel is carrying WWWW Pounds so it needs XX PSI,m< This wheel has YYY Pounds so it needs ZZ PSI and so on. (The right way to do it) They also may add a few PSI for safety (I have no problem with that).
Another problem is overloading the RV
Some RV makers use small wheels that spin very fast,, They recommend a max towing speed of 45MPH Of course we drive 70. This means the bearings are spinning faster, MORE HEAT and KABOOM.
Some folks look at a 15 year old tire and say "Tread's still good, I don';t see any cracking" and BOOM... IT blows 1 hour later.
And as the person I quoted said: Some folks... Well if not for BAD LUCK they'd not have any luck at all.. IE: 4x3 lying in the road (Yup, Been there all right).
