Will 295x18 tires look wierd for all four tires?

[Pasquale]

Hey guys, I'm just curious if I were to run 18x10.5 wheels and 295/35/18 tires in the front and the back, would that change the performance of the vehicle? Also, would that make the car look strange? By the way, I'm building a 69 camaro that I want to handle well for the street, not the strip.

Thank you
