Just a follow up post, I ended up going with BF Goodrich Premier Touring in 175/70R13. Im pretty happy with them, they werent that costly and they are very well make a Sentra with a stock suspension seem Very balanced. They have plenty of grip to take corners hard, but confidently. At the same time theyre still squealable if you really like the sound of tires squealing, and they dont feel like the car is overtired.
