I have not flown with the Goodyear tires yet, however, they are made in the USA and I consider that to be a huge plus! I installed them two days ago and have noticed a flat spot has already developed where contacting the floor. I realize most of that will round out during taxi but I have to wonder why someone cant develop a radial tire that does not have that issue. The other issue is that they are not balanced and I cannot find anyone that is able to spin balance aircraft tires.
