Novice DE - Question about tires

[phook]

Hello,

I will be needing new rear tires very soon. Currently on Potenza S-04 Pole Positions on 17" stock wheels.

Goal of the car+tires is for DE/AutoX - with some street/canyon driving for pleasure. Car is stock and my experience level is novice. Just some AutoX and no DE yet.

I've tried to do some research on these, but most threads keep recommending RE-71R or NT-01. I don't want to **************** up good tires, so I'm looking for the best tire for my experience level and won't break the bank.

Should I just get another pair of Potenza S-04? Is there a better tire I can switch to for my purposes?
