Personally I’d stick with Pirelli to match the front, and I’d have new, not second hand. (Second hand, if you can find them, might be cheaper, buy will need replacing sooner, so why bother.)
P Zero PZ4 are the normal choice, are Maseratis official choice, and offer excellent performance in the wet and dry at anything above low single figure temps. They are a good choice for a Maserati driven in the spring, summer and autumn (which is my use pattern).
But if you use yours daily over winter, you could try the P Zero Winter.
Or, sell your part worn fronts and fit a full new set of Michelin Pilot Sport 4s which are an excellent all year sporty tyre. They won the EVO tyre test in 2020 for best overall tyre. I’ve not heared anyone say a bad word about these.
