I have 5 almost new Nittos, barely have the edges rounded on 4 of them. One of those 4 has a vulcanized sidewall. The 5th was a spare and was only used to get out of the woods basically.
Yep non. Sticky verison of these are even harder to get, Ive only seen one set for sale of the sticky Nittos and pretty sure he isnt supposed to be selling them.
