while driving a

mostly country roads
Bought a nearly-new Ford Fiesta ST three months ago. On the day of purchase I noticed that there was a screw embedded in the rear-driver's side tyre (Bridgestone Potenza), though the dealership kindly offered to replace the tyre for free as a precautionary measure. The Sunew YS112 was the only tyre they were able to fit on the day (would have had to wait three days for another Bridgestone Potenza to be delivered). After only 1 month and 500 miles, I began to notice cracks on the outer sidewall. Decided to replace the tyre after 3 months and less than 1400 miles, by which point the side walls were quite badly cracked and even beginning to flake.
The car now has Bridgestone Potenzas on all four corners again, which has noticeably improved the car's handling. Will stay far, far away from the Sunew brand in the future, and advise others to do the same. I've never known a tyre to deteriorate in such a short space of time, after covering so few miles.
