This vehicle came from the manufacturer with dunlop sp sport 01 a tires (225/40R18) (August 2012 purchase). Within nine months (8800 miles) two tires developed sidewall bubbles. After contacting dunlop, they replaced two tires St no charge. At that time, the Goodyear/dunlop retail store slowed me to purchase a tire warranty on all four tires. Over the past six years and 80,000 miles, I have replaced fourteen (14) of these tires under the warranty and have had to purchase a warranty with each replacement tire. These tires are the only tires I have ever owned in almost 40 yrs of driving that have developed sidewalk bubbles. I have other tires from a different manufacturer with the same size tire on a different vehicle and they have not developed any sidewall bubbles. These tires are a safety hazard and should be recalled and replaced by Goodyear/dunlop. The first bubble was 6/14/13 and the latest bubble was 9/8/18.

Lost traction on a snow covered road driving at a slow speed of aprox 35 mph. The tires would not grip in the snow. The car slid about 100 feet and crossed a major state highway. The tires are made by primewell PS830. The tires are mfg in china. I'm making this complaint. After reading on message boards about primewell tires. Its seems to be a common issue with traction with the tires in snow or rain. In a brief they hold air some times and are round. I feel they are a danger to drivers of the car and other people on the highway. My wife was driving to work when this took place. She dose not drive fast on the county road we live on. As there are deer every where. When she told me what happen she said " I was going to die when the car kept sliding into the highway." There was a heavy truck that she passed behind. If the timing was different there could of been a serious accident. This is her first car that has traction control. When she said it something to do with the traction control. I explained what traction control is. She said maybe the tires have a hard rubber compound. I started my primewell search after that. There is something really wrong with the tires.

2012 Jetta with severe cracking on the inside of the tires. 205/55/16. Called hankook and they responded that they have never seen this before. VW dealer has photos of 20 cars with the same concern, but tires are not covered by VW, only through tire manufacturer. After reading all the other hancook optimo 725A tire sever cracking, this is a manufacturer problem and needs investigation.

20K service had been performed on my car, again I notified VW that the noise is progressively getting worse and that I can no longer stand it. I also notified them of newer issues that have never happened before starting to happen, but they told me lets fix this issue first before moving on. This noise that had been happening for awhile now has now progressively gotten louder and now making noises when I am turning, something it had never done before. They did a check, and all of the sudden told me that my tires is the cause of the whole thing. They had told me my tires are cupped and feathered, which seem pretty odd considering when I purchased the vehicle the tire where brand new and pretty good (hankook). It did not make sense to me because if it was my tires and if they were doing proper multipurpose inspections they would have caught this when rotating my tires. It really seemed like they couldn't figure it out so they just advised me to buy some brand new tires, or try to call the manufacture about replacements, well I did that and hankook said feathered tires has nothing to do with tire but with the mechanics of the car. They had notified me that the only way tires get bad is if the mechanics of the car. The manger word for word told me this "there is a reasno why your car is so cheap, maybe you should buy $2,000 tires, maybe the noise might go away", which infuriated me, because he is suppose to be the manager, but yet treats me with total disrespect and told me "we are done with this, we will not look into it anymore". this manager was rude and down right wrong to treat me like so (kearny messa VW, don't ever go there). I felt lost and scared knowing that they won't help me no more even though I still have my warranty.
