Nitto NT555 Extreme tires

I have these tires mounted on my new rims. Front is 245/45/17 and rear is 315/35/17. However, I haven't installed them on the car yet, because the car isn't done being built...I will tell you this though, I have read many good things about these tires and read they handle and grip real good on the street.. They are actually priced good to boot!..The main focus on my build was to make sure the car would handle extremely well. (That's why I went with the RMS front and rear suspension setups) And I feel a good quality tire plays a big role in that department...
