Nah, I'm still getting the same mileage as before. You'll be fine.

 

thanks! thats great to hear.

 

OK... I had an appointment today where I had to drive 70 miles through mountainous terrain, (I live in rural - wait, most of Wyoming is rural - :D) from home to Colorado. When I left, there was a light rain falling, but just as I got into Colorado, the rain turned into snow. BIG DAMN FLAKES, too - I mean were talking Super-size-me-corn-flakes here. I was a bit concerned given my previous experience with the OEMs, but the P-Zeros were fantastic. Even with almost a half-inch of the stuff sticking to the roadsurface, I didn't notice any sliding, drifting, or anything that would give me pause, let alone sheer panic like the OEMs. 2k-miles on these tires and by far the best investment yet.
Thanks Omicron for turning me on to these tires!:D

 

So does this mean you had to slow down from 130+ to only 110+, Doc? :D

 

I keep reading this thread and what I hear is less noise, a squishy feeling and better all around handling in all weather conditions. Given I don't drive my car in the snow and or rain (except once) I find it hard to beleive that the handling will be better in dry weather than the OEM tires. The OEM grip is amazing.

 

Anyone who says "The OEM grip is amazing" has never driven on a true max performance or even one of the better ultra high performance tires. The 040s are greasy when cold or hot. They are a compromise tire that is OK for general street driving during the warm summer months. I think what most people think is grip is in reality just the quick turn in response that the lower profile and stiff sidewalls give you. But that is what also gives you a rough ride, tramlining and road noise. If you really want to see how they compare, check this out:

It comes in 40th out of 41 tires surveyed. Then look here to see how well the Nero M+S did in it's category:

Another thing I find interesting is that the Avon (cheap?) "tyres" are also up there at the top of both surveys.

 

I almost purchased the AVONS!

They are old superbike tire manufactureres if I recall correctly.

 

Ummm.... yea. We are talking km/h, right? :D

These tires are far and away sooooo much superior to the OEM's. I had problems with the Potenzas on dry, but cold road surfaces.
Hey Dark8: Here's a website for ya; http://animation.filmtv.ucla.edu/stu.../coneindex.htm
(In regard to your "kill cones" message on your avatar)

 

Cone huggers! Surprised they aren't out protesting at auto-x events.....

 

Again, the squishy feeling goes away. And yes, IMHO the DO grip better than the OEMs. I used to think I was crazy thinking this, but it seems that other PZero owner's opinions are in line with mine.

 

Well I guess when the OEMs wear out I may have to consider these tires. Thanks for the education.

 

Have you recently driven an RX8 with the stock tires? The squishy feel of my Continental Extremes became less noticeable over time as I got used to them, but when I put the OEMs back on, the difference was significant. The PZeros are a better tire than the Contis, but neither of them have as stiff a side wall as the OEMs...

 

Yes, the "40's" may not grip as well as the Pirelli's, but I went back to them for the summer autocross season. First to burn the rubber off the OEM's first. And also because the sidwalls are so stiff, it does two things. First, the tires react quicker to steering input. Second, they act like a stiffer suspension w/o changing springs and shocks.

 

Well, I finally got around to checking the speedo against a GPS with the P-Zeros. Exactly as I did with the Potenzas, I drove a fairly long distance, (100+ miles), at various speeds from a dead start to umm... a little more than 85 MPH, on varying terrain - flat land & mountainous regions. My wife acted as navigator, and reporter. She read the speed from the GPS, while I drove and looked at the speedo.
The difference with the Potenzas was 2MPH slower, and with the P-Zeros, 3MPH slower. This difference was consistant across the entire speed range, regardless of location or terrain.

 

Have had my PZeros on for about 3 weeks. There isn't enough good things I can say about them. I have driven in dry and wet conditions. Absolutely no problems with traction in the wet. Dry driving - these things just suck to the ground.

I have a freeway onramp I can easily do 60 mphs on. Took it last night at 70 without any worries at all.

I didn't feel any "squishiness" as some of you have pointed out. They are mounted on Enkei MM2 18X7.5 - I doubt that has anything to do with it but I don't know any other explanation.

Road noise - very, very quiet. Definitely quieter than the Potenzas.

Simply amazing. I love 'em.

 

UPDATE:

We've had quite a bit of rain here lately and I have to say the PZeros (even with over 8000 miles on them now!) inspire confidence. Good traction, and not prone to hydroplaning.

 

great to hear, i think that just sealed the deal for me. am going to have to replace next month.

beers

 

Am finally getting mine next Thursday. :D

 

Had mine on for about 10K miles. Very happy. But - not a racer, and little/no icy streets here in Dallas.

 

I just bought the BFGoodrich g-force T/A KDW-NT's (225/45/18) and I love them! It's been really wet here the past week and they just stick to the road. It was dry for a little while today and "double wow" these tires are just amazing! In my opinion the OEM (Potenza) were crap (compared to this tire). This tire handles better and is definitely quieter (mind you I had over 50% wear on the OEM's at ~43000kms they were starting to get loud). The PZero was my second choice.

 

Got the PZero Nero M&S's on Thursday. Drove 125 miles round trip today at speed and they were great, just as advertised here. I was getting beaten up by the Potenza's, even in warmer weather, and the Pirellis provide a much smoother ride. I drive moderately but not real aggressively :p and can't really detect much degradation in handling at all. As far as noise is concerned, they seem about the same as the R040's on concrete, but are much quieter on blacktop.

Thanks Omicron for discovering these tires and for this long-lived thread.

 

Just got Pirelli P Zero Nero M+S on stock 18" rims to replace the 040s. Have put on about 500km and agree that the dry grip is very good, it rained and the wet grip is also very good. They are definitely much more quiet and provide a softer ride. There is a definite loss of handling precision, primarily on steering response, which is not nearly as sharp as the 040. My bet is that this can be compensated for once I get experience and confidence with the Pirellis. It will mean turning in sooner with the confidence that the grip will eventually happen. I am running 35 psi cold on all tires and need to play with pressures to take away a small increase in understeer. Has anyone experimented and adopted an ideal pressure?

 

I went to 38 psi and it made a huge difference, but still not as sharp as the RE040's.

 

Interestingly enough, I ran my car on a race track all day at our last annual Rocky Mountain RX-8 Club meet - and remain impressed with the tires. But I am far from an experience or even very skilled race driver. What is worth noting though is that one of our members who IS a very experienced race driver took my son out on the track in my car to give him a thrill ride (he is SO much better at it than me that I thought it would be illuminating for my son... and it was... ), and when he got back into the pit he was commenting on how impressed he was with the Pirellis on the track. I've both ridden with him and watched him drive, and so as far as I'm concerned his comments are a pretty good testimonial to these tires on the track.

 

I've got about 4000 miles on mine. During about the last 1k miles, I've noticed that one seems to thump when I start out in the morning. After about three miles (as I enter the freeway) the thump is gone and all is well.

I will get it checked out, but thought I'd see if anyone else has experienced what seems like a flat spot on the Pirellis.
