I believe blowouts have become less frequent but I put those is a category of mechanical problems that can cause an accident where no blame can be assigned. Besides medical events, there are a host of other events that cause accidents where no blame can be assigned such as colliding with a deer (fairly common is many parts of the country). The point is some accidents are not the result of any wrong doing.

Tire blowouts are a thing of the past,,,,,,,,,,,,,,, almost. Because of the increased strength of tires now, steel belts etc. However, a blowout most likely, (not 100% of the time), is because of a nearly worn out tire or a tire that has seen a lot of abuse, like high speed thru chuckholes etc. So again the best protection is to be aware of the condition of your tires. Question, have you seen the folks who bounce off of the curb while parking or turning? Not a accident, it can damage the belts in the tires, and Joe Citizen needed to be aware of his/her errant driving.
Tires will last different amounts of miles, depending on the driver, speed, chuckholes, curbs, road hazards etc. A rule you might follow for a good quality tire, maybe consider 30000 miles as the time to change to new ones, good insurance but then each person needs to do their own design of a "safety net". I change them at 30K and I am a very cautious and not speedy driver. Feel free to do as you wish, these comments are meant to be helpful. Also, if purchasing new tires, do a very good inspection of the tire before it is mounted, the technician needs to willing to show you how to look, for bubbles, seams, weak spots, badly out of balance, there are these and other hazards to look for on a new tire. Someone selling almost new, used tires for a bargain????,,,,,,,,,,,,,,, NO WAY ON that one. bbbbbb
