What Non RFT will drive most like my OEM

[big wave dave]

I have a 2006 325i, what Non RFT will give me the same tight ride yet be quieter and more durable than the OEM RFT? That is my desire so if you have made the switch, what tire do you like? I live in SoCal, call so I can run a summer tire all year long, no snow and minimal rainy days.

If you want durability, you should go for all seasons. Summer tires will wear down faster, since they are softer than all seasons.
If you want something quiet, you'd get "grand touring" type of tires, rather than max summer performance.
It almost seems like you want to get GT all season tires.
