If I'm reading the date code right, that's an 11 year old tire. If the rest of your tires are the same age, you will likely be having this issue recurring with the rest of them.
If it blew out the sidewall while just sitting there, parked, then it was definitely very weak. When spinning, a lot of heat is generated in tires, which often causes the blowout, and of course the centrifugal force tends to cause pieces to go flying.
I paid a bit over $210 for a single 295/75R22.5 tire when I pinched the sidewall on an outer dually on a curb. The shop was in Bridgeport, WV, and they mounted the tire without removing the wheel from the vehicle. I did not have the luxury of shopping around, I had to take what was available, so I could get back on the road as quickly as possible.
Shop around, see what kind of prices you can find. Don't forget tire rack as well, but then you still have to pay a shop to mount the tire.
While tires are on your mind, look at your other tires for the date code. That 1009 in the photo that is inside an oval, means the 10th week of 2009.
If your tires are over 7 years old, you should be planning and budgeting for their replacement. If they are over 10 years old, you should be replacing them.
