All-weather tyres with high load index on small cars

Hi all, three weeks ago I bought new all-weather tyres from the tyre dealer. I have Hankook KinERGy 4S 2 H750 XL FR in size 195/55 R16. I unfortunately let myself be blinded by the good price until after the assembly they told me that they are tyres with a higher load than I would ever need for my car, Hyundai I 20, year 2015. Can I now have any disadvantages in terms of comfort or safety? What I notice is that they, compared to other all-weather tyres, are already a bit louder, which doesn’t bother me now, but as long as everything is safe. Unfortunately, when I bought it a lot went wrong, which I already posted here. A tire was defective during assembly, then I had to go again because a tire was probably wrongly balanced. Have a nice evening and thank you for your answers.
