W.S.
I think stock tyre size for your car is 195/65/R15, and you should stick with it.
Michelin, Continental, and Bridgestone are some of the reputed tyres brands. You may choose between them, any series which matches your budget.
When you change your tyres, have the wheels balancing and alignment done from some reputed and good shop, and in my books, these both are a must after tyres change. Hopefully, your issue will get resolved after these. IN SHA ALLAH.
