So today I got some Hankook Ventus ST's on my truck in 275/60/17, they are a middle priced performance tire. All I can say is wow, these things are awesome, they replaced Grabber UHP's which I could smoke into 2nd, these new ones I only get a chirp. Anyway here is a road I use to test everything I own and do
Horning's Mills, Melancthon, ON to Terra Nova, Mulmur, ON - Google Maps

If you cant tell from the picture it is a very fast, tight twisty road. I was pushing and pushing and could barely get a noise from them, I ran out of nerve before I ran out of tire
