The spike is unremarkable and follows the standard design; there is nothing special about it. However, considering the circumstances in Hong Kong, he does a good job of keeping his foot in the tire. The price point is really reasonable for a tire that offers such a high level of traction on icy and snowy surfaces. The braking is quite good, and it behaves as expected. The acceleration is fairly sluggish, in contrast to the eighth "Hakke," but the value that you get for your money is more than sufficient. It seemed to me that pressure had a significant role in lateral slide, so I'll start there. The tire does best when inflated to a level that is slightly higher than what many drivers are accustomed to doing. This number will be from 2.3 for an R14 with a profile of 60 and a vehicle weight of approximately one ton. If you decide to experiment - be careful. Some cons: After a day, I finally severed the cord down in the pit. But the hole was deep and steep, and it's unclear how much of an impact the sidewall had on the accident.
