There must be another "Kinetics" tire model in your area. Over here, the Kenda Kinetics is just a cheap tire often spec'd on entry level bikes and department store bikes. They need inner tubes. It doesn't say what compound it is, but I know for a fact that they're the best wearing knobbly tire I've ever used. I do rear wheel brake skid-drifts on them all the time. I only ever buy one replacement tire at a time for those when the rear gets bald. I always put the new tire on the front, and put what was on the front on the rear. I've gone through a lot of them over the years.
As far as the upper market tires are concerned, the rubber compound is usually marked or written on the side, near the brand logo. There's all sorts of designations and you'll only really know what they mean when you look them up on the brand's website or brochure. Maxxis "super-tacky" for example is their racing compound... very soft and yep, tacky to the touch on a hot day... with a slow memory. By that I mean, if you pinch a knob and twist it then let go, you can see the knob very slowly go back into shape. They wear out quick, but they win races - which is what they're made for.
From memory (which isn't too good these days) the normal compound Maxxis 2.35 HighRollers have an ugly orange stripe on both sides of the sidewall and is a lot cheaper. As a general rule, a cheap tire usually
has all-round hard wearing rubber compound. The exotic compounds are more expensive, and more often than not, wear out a lot quicker.
The Triple Compound in the BigBettys for example is a hybrid, and has three different sorts of rubber compounds going along the diameter of the tire. I think it's got medium compound on the side walls for ideal rebound response, the outer row of knobs on either side of the tread pattern are soft compound for cornering grip, then the middle group of knobs are hard compound for better braking bite and longer wear. That's why the Schwalbes are so expensive, I guess...
