As my 2 fat friends above have pointed out, these are not a great tyre but you get what you pay for and that is a very good price indeed.
If you intend to actually ride them off anything bigger than a drop-kerb, get some tan-wall V-Monsters. Recently re-issued and they do a 2.1" as well as the 1.95" if you look hard enough....... Swear by mine, and i've had those cheaper ones to compare them to. Just not a patch on good rubber and let's face it, tyres are THE most important part of your ride if you're gonna have a go. I know, I bear the scars of Odyssey Barefeet tyres....... Ouch!
