I'm in SWFL and have the 500's on my 15 SRT. Holding up well. Has good grip. Wet holds well. Dry is pretty sticky. Got plenty left on them after 1.5 years and I'm not easy on them. Only thing I could complain about is they tend to be a little out of balance for the first couple of miles til they warm up. I don't notice it anymore after 10k miles. I call that a trade off for the cost vs performance. Sure, there are much better tires out there but not for what the 500's cost. I probably will buy again when the time comes. I also can pull 1g turns and stops with them. I vote for the 500's.
