5-star rating and the least expensive, that's amazing! Not time to change tires yet, but this will be my next set. Thanks.
Wow thats horrible and I wish I knew the solution to all of what you experienced! I've had the Hankook Ventus V12 Evo's for a while now (probably around 2 months) and haven't came close to any of the things you have listed. The ride is hard at times but I had the Micheline tires that came stock with the car and the feeling was identical so I dont believe it was the tires. I've also gotten the car close to the highest speeds the ISF can go and didn't feel any one of the things you have listed either. I am not a Hankook promoter in any way so dont get me wrong! Just listing my experience with them and making sure everyone on the forum didn't think that these tires perform poorly because they really do perform great.Nice tires but...
This is my story, last month I needed tires really BAD so I had to rush to a good local tire shop, buying online was out of the question as I didn't have time to order, wait for shipping, etc. They had these Ventus V12 Evo in stock and they look GOOD! I decided to give them a try (stock size) and so far it's been a nightmare! In a 2-week period I've gone 4 times to that shop and 2 times to another one, trying to find out why my car vibrates at high speed! My wheels have been re-balanced on every visit to the shops, 6 times in total, and every time I go (probably 2 days in between) they're out of balance again!!! Tires are filled with nitrogen and tire pressure is at OEM level (I believe 35 PSI). I've been next to the guy doing the balance every single time and the machine says it's OK (after adding the proper weight). The car feels so smooth and quiet driving below 80 MPH, but once you hit 80, it's like an ON-OFF switch, the car feels so unsafe, vibrates so bad that you can see the visor vibrating, you put your hand on the passenger seat and the vibration is bad. The steering wheel remains centered, it doesn't pull to any side though. I drive HARD, and my daily conmute is driving on highways, so going over 80 MPH was the norm, now I get so irritated because I can NOT stand driving a Lexus IS-F, a $60K+ car, with this kind of problem.
Now some answers:
1. I asked the local shop to return the tires and pay the difference for better ones, maybe the stock Bridgestone or the PS2, and they said NO, they've been used and I can't return them.
2. I went to the Lexus dealer to check the car and see if the vibration was caused by something else. Everything was OK, they confirmed it was the tires.
3. I talked to a friend who has track experience and have gone through different kind of tires, I didn't mention my problem but mentioned tire's problems in general. At one point he talked about the same issue that I'm going through and he said it's caused by CHEAP tires.
So here you have it, this is my experience with the Hankook Ventus V12 Evo. My tires are 1-month old and I'm in the market for another set, probably Nitto Invos, great reviews all over the net.
