Nexen tyres 165 60 14. Bought 4 units, 1 piece got buldge like this after 6 months. Another piece got same buldge after 8 months. What is the issue? Manufacturing defects? Need spend more money for replacement tho the shop accept trade in, but I still at losses. Fml

Lol nexen is crap brand? Thought I'm gonna enjoy some Korean technology. It was my first time bought nexen tho. I've changed to Dunlop j5. Definitely a lot better

Hmm I've never had a single bulge in more than 30 years driving various cars and tires!  But I have only used low end brand once which was GT Radial more than 10 years ago and that was also for a relatively short time before I sold the car. Even for Hankook I only have tried the V12E2, not even their mid range or low end models. The most shit tire I have used in the last 10 years was only the Continental CC series that came stock with my wife's car but they didn't bulge, just shit grip.

being a former medical sale rep who was always in rush of time, and traveled the whole peninsular Malaysia through many rural area in hastily fashion covering huge miles at a time can have very different experience

Mine happened exactly like yours but buldge from the side
Scared it will burst any time

Side buldge is different. That one is due to pothole etc. Get it replaced if you worry. Or just use till it burst. Anyway, its like a gamble. Sometimes can last, sometimes cannot. If u always drive fast, better change.
