Brother I am not very good at tires. I have only bought tires two times for my rides. I put a nato tire in my father's honda city and I replaced by cultus tires with bridgestone. The well known market tires are dunlop, bridgestone, machlein, good year, yokohoma etc but they are expensive. You can try to find some second hand piece from the kho of sultan.
Brother my vitz came with good year tires and I am using the same one till now. I will change them after damaging them to best extent
You can get the "good year" second hand tire in reasonable price. If you do not drive much they will be enough for you to pass at least 6 to 12 months.
Sir, all good tires are "good" for vitz You can go for yokohoma. Michilen is also a good option (Many people say it is bad for Pakistan, but I have seen it being used in Saudia. If it can work in saudia why not pakistan?) So you have many options. and dunlop to dunlop hay all time favourite. Jis marzi car main lagwa lain.
I do not know about tires much so you can post the question in tire guru thread. I have seen you getting good help in vitz fanclub too. Best of luck
