It's very cheap but quality is absolutely no problem.
When OEMTire came to the limit, I chose a candidate, I bought it because this Tire was the cheapest. I knew the Manufacturer itself, Pirelli, well, but this series Tire was a little uncertain because its identity was unknown, but it was not a problem at all.
I brought it to Circuit and tried running, but it turns very well. Grip power was also comfortably tilted without any problem. (* It may not be reliable because it is pretty much Sauce and amateur's running impression)
DragonMark aside from Tire is also cool! W (Perhaps no one notices it)
Since we have not tried running on a rainy day, the wet grip ability is unknown.
