What now?
You can call me a snob all you want, but this is the same lesson NASA learned with the Challenger space craft. Specific compounds perform optimally in a very specific temperature range, outside of that range you run into issues. Being that tires have one job, to provide friction, and that they are the only point of contact between you and the road, it seems really silly to advocate for All-Season tires. Sure, they aren’t always going to be as bad as people make them out to be, but that’s the catch 22, they’re never as good as anyone who has driven on dedicated summer or winter rubber comes to expect in the appropriate temp range.
All I’m saying is that you bought a performance car, asking about all season tires on this car is like asking how hard it would be to swap the naturally aspirated 1.6 from the base fiesta in. Anyone could do it, and I’m sure the motor isn’t “THAT bad” but why even bother? You bought a car specifically for its promise of performance, why dumb it down? At that point just get an ST line.
Now if we’re all done taking shots at each other, there have been several recommendations and from my time in the world of tires I know the Pilot Sport A/S 3+ is getting old, they are good but hardly the performance all season benchmark that they used to be 6 years ago.
