Tire wear and landing cycles.
Kevin: I assume you mean uneven across the tread of each tire. Such wear is expected and typical. The spinup of the tire at contact on landing literally smokes the tire and creates rapid wear. Because the landing gear us unweighted at that moment, it is drawn in towards the center of the plane. Thus the outer tread area is the area that takes that wear. Subsequent wear during taxi is more uniform and, due to the constant contact across a broader area of rubber, much slower to take tread off the tire. Whether or not this is happening too fast on your plane is unclear to me. 30 hours does not seem like enough hours for visible tire wear, but I don't know how many landings you have done or how much wear you have. Tire pressure might be a factor.
Many owners rotate the tires left to right, perhaps at the condition inspection, to put the remaining better tread to the outside. That can maximize the number of landings. Or just replace them. Having had a flat nose tire on landing once when 1000 miles from home, I am pretty shy on extending tire wear. I consider my tires to be three single points of failure, any one of which can significantly mess up my travel plans. (My flat was due to creases in the tube, not tire wear. But still, I was grounded pending a fix.) So, I have replaced, not rotated. Nonetheless, rotating tires seems to be a reasonable, sound practice.
Note, the tube for the nose tire is not a commonly stocked item, so I carry a spare tube in my plane. Learned that the hard way.
As to the brand/type of tire, there are many threads on VAF about that and an even larger number of opinions. I don't have an informed opinion. FWIW, I'm thinking of trying the Desser retreads next time to see if they last longer as some have reported. I think I have AeroClassic tires now, not sure.
