Tire Sidewall problems of the 2010 Ford Focus

Three out of four 215/45/r17 douglas tires bought at walmart in piqua oho ended up with bubbles on the sidewall a week after the year from the day they were bought. One right after the other. When I went to have them replaced at a discounted price, I could not because I had to put a spare tire on (it is considerably smaller) causing the tread on one tire to be slightly uneven from the others. So this voided the warranty. Now tell me how passenger side and driver side front tires both end up with sidewall bubbles and one blows out within a week apart? nothing changed in my driving routine. Bought two nearly new tires to maintain my ability to get around, and a third tire develops a bubble and had to be replaced. The last tire is slowly leaking!? I drive to work and back. I live less than 2 mins from my place of employment. I do still have my paperwork from buying the tires. Btw the warranty was never registered correctly because when I tried to call about it they had no idea where to find it. I had to send all sorts of paperwork to them and still got no results.

A mechanic noticed that the inner sidewalls on both front wheels were splitting (as if along the seams) on the goodyear weatherhandler 215/45r17. The tires were fixed before any blowout occurred, but goodyear refused to take responsibility. Three separate mechanics from different garages had never seen anything like it, and confirmed that it did not occur from daily wear and tear.
