Yup for 15, there's no PS4 but only up to PS3. V12E2 would be the best choice there, best value for money. Other notable choices are Goodyear F1D5 and BS RE003.

PS3 is excellent choice also but if I have to choose between PS3 and V12E2, I'd choose the V12E2 because it's more value for money as its much cheaper yet the performance is just as good if not slightly better in the dry than PS3. PS3 maybe is a bit better in aquaplaning resistance though. One minor issue with PS3 is chipping when driven hard but PS4 is also still like that.

No I don't think parking under roof or in the hot sun makes much difference in therms of preventing chipping. Chipping is more due to driving them a bit harder and pushing the load a bit more in the corners. So far out of the tires I have used, actually all of them have chipping but just some more than others and the worse for me were F1D5, PS3 and now also PS4. Despite the chipping though, all of those still performed well as expected through out their lifetime.

RE003 has the weakest wet performance compared V12E2, PS3, and F1D5. It also wears off the soonest. It has the best dry performance though.

How much is cheap for you?

Then you can still get the Hankook V12 Evo 2, best value for money tires now because it's high performance almost as good as Michelin PS series but price only like lower mid-range comfort tires.

You mean low rolling resistance for fuel economy, or durability?

Reasonably long enough, should last around 50k km for normal drivers.
