I looked at the reviews for the Douglas performance tire on the Walmart website. 15 one star due to tire failures, probably due to the fact there are only 3 plies in the tread, and 1 ply in the sidewall. The current tires on my 2014 Sport have 5 plies in the tread and 2 plies in the sidewall. I haven't had a tire failure in almost 50 years, and do a lot of cross country driving. With the poor shape of most of the roads everywhere, I would be afraid to use a tire with this few plies at speeds over 45mph. I would rather spend more money to feel safer on the road. Just my 2 cents.
Meh.
I've had TWO failures (belt breaks!) on my Jetta in its years of ownership -- one on Michelin MXVs (!) and the second on Uniroyal Tiger Paws. Both could have easily been catastrophic failures as they were on the front axle, both were on well-respected "name brand" tires, and both wound up costing me money as warranty or no warranty they happened while away from home on a trip where hauling the dead carcass home (where they were originally installed, and where I could file said claim) was impractical. Neither resulted in deflation at speed (just hideous vibration that made for an immediate "pull over now and change that thing!") but that's more a matter of luck than anything else.
I drive 70-75 on the highway and when out west where the limit is 80, I do 80-85. I've got about 30,000 miles on these tires now, they're showing very good tread life wear (I expect to get ~50-55k out of them before they're to 4/32, which is where I change tires) and their performance has remained perfectly acceptable. When these wear out I'm going to buy 4 more of them. I rotate them when I change the oil (myself) and they get a good inspection on both sides plus the tread area -- they're doing great.
Any tire can and will fail if physically abused either physically or through extreme underinflation leading to heat-related failure and MOST sidewall failures are in fact from exactly that. Of course nobody ADMITS it after the fact and if the failure is complete (separation sufficient to result in catastrophic air loss while in use) then the evidence is usually destroyed in the blowout. But as I've noted in the last ~15 years I've had two serious tire failures, neither was abuse-related, both were on my Jetta, both were on MUCH higher-priced "name brand" tires that everyone thinks are great and, well, the BFG Comp2/AS tires I replaced with the Douglas ones (that are on the car now) were showing signs of tread/belt separation failure when I replaced THEM (they were roughly at my 4/32 limit, but when they were next rotated I would have condemned them anyway after seeing them off the rims on the scrap pile -- two of them had visible indications of trouble right at the tread/inner casing molding line that a close inspection would have definitely caught.)
