Guys I see that there are not many ppl using Dunlop tires here or maybe it's not popular? Any reasons behind it? Are they any good?

Reason I am asking is Cos my car came stock with Dunlop sp maxx sport gt 245/40/zr18. I was a little disappointed that it came with this tires but the only consolation is probably the tires are made in Germany.

Can someone enlighten me on this tires? Currently my new ride less than 2000km. So far so good but I haven't try the wet grip yet. Would be good if there are previous owners of this tires can give some feedback.

Thanks.
