Yeah, they are all the same, right BTW, Hankook are the sole tire supplier for the DTM, the German racing series closest to F1. And Nitto is manufacturing one of the best, long lasting and affordable amateur racing/track day enthusiast tire.
Tire is either sticky, has a good or excellent grip, and is bad for gas mileage because of the roll resistance. Or it is "plastic" and doesnt have much grip and therefore doesnt hurt the comsumption much. Think Michelin Pilot Sport vs Michelin Energy.
My current Nittos compared to the previous Bridgestone RFT's are:
-less than 50% of the price
-at 7k miles quieter than the Bridgestones at 15k miles(when they were replaced due to wear)
-judging by the wear will last at least 3 times more then the Bridgestones
-may have slightly less dry grip, but it is very hard to determine only by feeling
-have definitely less wet grip
Now the tire installers dont hate me when i show up with new tires
