Sports package Potenza tires...
 

So since we can't rotate the tires how many miles you guys think these tires will hold up for, assuming proper inflation.

You can rotate side to side but not front to back... and length of life will really depend on how you drive and your alignment settings.

I have 6k on mine and TONS of tread left and that is with a track day! I also drive really aggressive on the street with late braking and proper race lines through certain turns in my area.

:iagree: I also have 6000 miles and I'm not as aggressive driver as you. Almost brand new thread still.

These tires are directional
 

Remember that these tires are directional. The only way that you can rotate from side to side is to dismount the tires and remount them on the other side. In this manner they are able to stay pointed in the correct direction.

On the subject of the OP, about 20K is all.
:tiphat:

uh, yeah ... i know :happydance:

No, they are not. Go out and look at them - you wont find the rotation direction indicator on them.

There are no directional arrows, but they are labled "outside" on the tires.

So can it be rotate side to side without dismounting the tires or not?

Yes, you can.

I was looking at my tires today and I don't think I will get any more than 12k out of them. So far I am liking the Direzza Sport Z1 Star Spec for replacements.

Dunlop Direzza Sport Z1 Star Spec

I had those on my old car and they are great tires. Problem is for the Z they don't come in 19" sizes.

Was just about to post that heh. Yeah, those are right on top of my list if they make them in 19's eventually.

is it just me or are the stock potenzas really loud?

Not just you.

Get the Potenza RE-11,latest design...

The Nitto NT05 tires seem to be getting really good reviews. Has anyone tried those? I am still on stock with about 4000 miles of moderate driving and they still look new. When I saw the 140 treadwear rating I got a little nervous thinking they would last 8000 miles or so but the are holding up pretty well.

For new tires I want to like the Nitto tires but back when I had a turbo AWD Mitsubishi everyone raved about the Nittot NT550 tires so I got them and didn't like them. The sidewall flex was much more than whatever the factory tires were. The stuck fine but I always seemed like I was leaning or slipping when I entered a turn. But these are different tires, different sizes and 10 years later so a lot is different.

Just got the Potenza RE11's. Mounting is on Thursday will let you guys know how they feel!

I have the NT05's on mine, probably some of the best street tires out. 285/35's, btw, these sit comfortably on 9" wide base 18's.

I'm hoping to get at least 20k out of them for just street driving. Overall they have been great, much better than the junk tires that were on my 2005 350Z.

When I get new tires, I'll likely be going with these.

I was also thinking about getting the Nitto NT05. I like the reviews of the Goodyear Eagle F1 GS-D3. They are supposed to be excellent on dry and wet pavement.

NT05's are actually great for track use as well! I have a pair of NT01's for drag days, basically street legal slicks, f'in love em.

Potenzas have always been loud imo.

Red370 I see you have the NT05. I've read a lot of good reviews on this tire and I'm thinking about putting them on my Z. I noticed you have 285 on the stock 18x9. I am wondering do the NT05 run thin? I have the 19" Rays the NT05 for the 19" come in the OEM sizes 275/35/19 rear and 245/40/19 front. I think the Bridgestone RE050A that my Z came with to be a bit stretched over the wheel and can't image running a narrower tire. On another note how do the hook up on the street, compared to the NT01? Need some more traction here!

i believe nikon fm has over 14k on his stockers

I've had the RE-11's on all year. In general they rock, more grip and less squeal than the RE-50A's. Slightly less grip than the RE-50A's at low temperatures until you get some heat in to the tires. Despite the reduced grooving I came 0.1 seconds away from taking raw FTD at a wet auto-x with these. The bad news is that auto-x is rounding over the edges on my front tires pretty badly. Overall tire wear is pretty good though, better than the Star Specs I had on the G35. I think you could easily get 20K+ miles on these without auto-x or track.

have you tried increasing the air pressure? or maybe get an alignment with a bit more camber/caster?
