Tires are like anything else in life, you get what you pay for. Everything on your list is garbage. You can pay $280 for a set now and another $280 in 9 months or you could pay less for one good set and ride on them for a couple years.
If you are driving a higher performance car, your tires shouldn't last 9 months.... depending on how much you drive it.
10k mi is normal on mine, I don't drive like a grandmother, nor do I drive like a ricer. I have a fun balance, and I get alignments fairly regularly... every 90 days or so.
