The tires do anyway.  (I don't mean to offend the kinky...)

They're not the all around tire that they (Snafu) would leave you to believe.  I left them on for testing purposes after buying my bike, and fully regret it.  They have no grip in park.  They're decent for street, but the rubber is so hard that when you need to stop now...  You lose have of your tire just thinking about pulling the lever.

I don't know who I would recommend this tire to, but I've tried it on street, trails and park and it flopped in all but the "perfect" conditions.

Go for a softer compound like those in any other brand than pick these up.  I have the rashes to support my regrets. 

Wooooord...
