Should I change gears or not?

I have a 3.23 rear. Im going from a 225/70r14 on stock wheels to a 275/60 or 295/50r15 on light weight weld knock offs. I like the way it performs on what I have, but I want a wider tire and I’m adding a suregrip. Will I be ok with what I have or should I go a bit deeper gearing while I’m at it?
