I am searching for same stuff tyres for new city
As long as size is concern yeah better go for stock size 15"
However I am bit confused regarding tyre size should it be 195/60/15 or 195/65/15 I have visited lots of shops every one giving their own reason go for 65 some says 60 is best, I personally saw the difference by placing along side stock tyre, 195/60/15 and 195/65/15 and yes 65 was quite a big and as per calculation 1.3+% difference for 60 and 4.1+% for 65
For tyre brand i have heard good abt Yokohama DB series but in this price you can get Michelin or Continental too.
