Hi guys. Lets not confuse profile with width. Width being your 2.1", 2.2, 2.4 etc. Profile being the height from the edge of the wheel rim to the top of the tyre knob. Profile is another figure which should read something like: 59-XXXX etc. obviously this will change from manufacturer to manufacturer based on their width measurements not all being the same. Eg: a conti 2.2" is very difficult to say a Kenda 2.2",especially when comparing UST models. There is no clear cut rule to how you measure a width of a tyre as various methods are used. I am running a Conti mountain King UST 2.2 on the front and it looks more like a 1.95 - 2.00" width. It has a much lower profile than the tyres which I have previously used but I have seen to cons to this so far. It sheds mud, water and anything in its way with ease. I would recommend this to anyone. I am still running a Specialized Captain Control 2.00 on the rear ( wider than the mountain king front with a bigger profile). I know the preference is to run wider front than rear, but in my case this works for the moment and resistance is negligable. When its time to replace, I will either fit a Mountain King or Race King 2.2" UST. (By the way, my wheels are 26's). My home trail is Tokai Forest and these tyres are wicked.
