Default mixed tires

Since MPSS are not available in 305/30R19, how big of an issue would it be to mix tires?

Front two tires would be MPSS in 235/35 R19
Back two tires would be PS2 in 305/30 R19

The car is AWD 997.1.

Any comments and/or recommendations are welcomed.

did find a 295/35R19 alternative for a MPSS (instead of correct size 305/30R19 PS2)

Re-71Rs for the most grip
RE-11 for durability
AD08R for feel

Mixed tires are okay with some caution:
  • Do not mix one side versus the other, i.e. two left versus two right.
  • Mix per axle.
  • Stickier tires in back.
  • Use caution especially on the warm up.
  • If it feels bad warm (lots of oversteer really bad, lots of understeer, no fun) get off the track. If it pushs a lot cold, give it a lap or two to come up to temp.
  • Not for beginners. You need to be able to feel grip and have some car control skills.

IOW, put the tires with least grip paired in front, the most grip paired in back.

I don't think I'd mix brand new tires however. Not worth the hassle.
