i have the rubino pros...i find them pretty easy to mount and unmount, but i started to see the threads (just a couple small spots) on the rear after about 2 weeks (i skid more than i should)...anyways i rotated the tires, and i'm trying to take it easy on the skidding...i'll see how long i can make them last...if it weren't for the durability issue though, i guess they're okay, they're lighter, and seem grippier than my last tires (performance gt2/k)...but i think my next tires will be something else
