245/40-18 + 315/30-18 set up on 997 C2S
Can someone verify that I can run on my 06' 997.1 C2S: Non AWD.
245/40-18 + 315/30-18 set up?
Any performance differences on DE level with 305/35-18?
I know there is OD differences:
245/40: 25.55"
305/35: 26.42"
315/30: 25.35"

I have run the 315 rears. If you are not really pushing/sliding much, it works. As soon as you start moving the car around more, PSM can start to freak out, especially braking and turning -- gets really invasive. This is just my personal experience in my 997.2, fwiw. The 305 works without issue.
