A little of both. 30 psi is not the optimum pressure for a DR for sure. I run them on the green car year round, but it's not a daily.
If you're dead set on running them, look at Nitto's. They will last 10k miles on the street, are decent in the rain and don't suck too bad at the track. If you're not worried about life span, just stay with M/T's and run them around 28psi everyday, then lower that when you're at the track.
