less than one hundred.

28,000??

27k

:icon18: street racer/drifter?

13,000
then switched to Pilot Super Sports...

I'm at just under 11k miles on them now, and they have enough tread to just cover the lip on a quarter. I'll definitely be going to the PSS's after, which should be better on road noise, tire life, and dry and wet grip. They were even cheaper than the stock potenzas on Tirerack, last time I checked.

I am at 40K, the rears are like drag slicks now but the fronts are still ok.

A little over 24,000 km's on mine. All four tires are showing more wear on the outside than on the inside... what's this about the camber on the Z causing this wear pattern?

38k still going, never rain in california anyways. waiting for new rims so i can get new tires with it(excuse for getting some new shoes HAHA)

^^"
 

35K FOR REAR 40K FOR FRONT:tiphat:

I'm at 24,750 and still have pretty good tread. Only the outer most tread is noticeably worn down.

mine wouldn't pass inspection anymore btw... not just because i liked the PSS :)

I got about 16k out of mine. The last tech to due an alignment on my Z forgot to tighten down the adjustment nut on my camber arm so specs were shot. Good thing I found this in time, I was all the way down to the cable.

The tires were already worn prior to this, I would have maybe gotten 20k out of them if my alignment wasn't FUBAR.

For the stock Potenza's, I had 20,000 miles and my rears were done. Fronts had a little bit more tread life but I got rid of 'em anyways and put on Michelin Pilot All-Season (A/S) tires. I've got about 36,000 miles and change on 'em. They are starting to wear now but these have held strong for long hauls. :)
