Maybee it's to keep you all entertained.
Any of you remember sweetskinz tires, found a set for cheap today and decided to thrash them and see how thay held up.
First off, putting them on is a pain and a half.
To the ride portion, the tires do not hold up to hard abuse at all. They don't grip well at all.
To sum it up if you get offered a set for cheap, avoid them at all costs.
