I doubt it... and it really doesn't matter if you are, or not. I asked about the RE-01R product... you place a premium on the lightest tire you can get, so you opt for the PS2. If it makes you happy... that's fine. The only issue I had was when you tried to pin what are clearly two different kinds of product against each other and claim one superior where neither were truly a competitor to the other.

Moving on... your sig mentions LSD. You have an LSD in your car? Who's unit? How much did it cost and where was the install performed? What's it been like?

How does DCS work in conjunction with the LSD... any big gotchas to the install?

You asked why we weren't talking about this tire when all we talked about was 'eeking every bit of performance out of the car'.
A heavier tire doens't add performance.
Yeah, I know a few pounds doesn't make ALOT of difference, but it does.

Also, Bridgestones have stiffer side walls, resulting in a harsher ride.
I have a stiffer suspension, hence I don't want an even stiffer ride, on my daily driver.

Actually, I NEVER compared these two tires to one another.
I clearly stated that all Bridgestones tires, like GYs are heavy !
I won't trade weight for tire wear or grip.
That was my point of every post.

Actually, I'm going to check out the new PZero probably.

LSD is a Quaife ATB unit.
It works perfectly with the BMW DSC/DTC, as Birds in the UK has shown it and Auto Sport Magazine drove it and loved the feel.

Yes.

A heavier tire doens't add performance.

No. To the extent that the only change is increased weight, then yes, you'd be right. But to simply say "a heavier tire doesn't add performance" is just wrong... if not at the very least, incomplete. If the tire's sidewall increases in strength and the tire's tread surface increases in traction, and if both changes are accomplished with only a minimal increase in weight, well then, you better believe performance has been increased.

Yeah, I know a few pounds doesn't make ALOT of difference, but it does.

Which is why I have chosen a very lightweight custom rim... to give me the option of using the highest specific performance street/track tire available.

Also, Bridgestones have stiffer side walls, resulting in a harsher ride.

For the most part, I'd agree with you... but the general feedback on tirerack doesn't seem to have the same findings. Tirerack's own testing found the actual "daily ride" quality to be quite good.

A direct quote from Tirerack.com: "While Extreme Performance Summer tires normally trade off ride quality for steering response and handling, the Potenza RE-01R not only delivered the best ride of the four tires, it delivered surprising civilized ride characteristics that could have easily been mistaken for those of a tire delivering far less performance."

I have a stiffer suspension, hence I don't want an even stiffer ride, on my daily driver.

While I can understand your desire to ease the daily commute, I hope you do know and understand that before any of your "stiffer" suspension components get a chance to do their job, your tire sidewall is doing ITS job. And, if the tireside wall compresses before energy is transfered to the suspension components, then your contact patch is compromised before the suspension even comes into play.

Good suspension performance starts with rubber... not ends with it.

Actually, I NEVER compared these two tires to one another.

Maybe you felt that way... but I wasn't the only person who's perception on basis of your comments felt otherwise. Don't take my word for it... look at the comments of others who felt the same.

I clearly stated that all Bridgestones tires, like GYs are heavy!

And that was responsive to my query on specific Bridgestones, the RE-01R. So it made it have the perception of a comparisson. Can't you see that? If I would have said... what does everyone think of the Michelin Pilot Cups... and you would have responded, "The Cups will kill you if you touch so much as a drop of water, go use the PS2 product instead," you'd have the appearance of comparing the Cups with the PS2s. And I'm sure you'd agree, those two products don't compete with each other.

I won't trade weight for tire wear or grip.

Even if performance INCREASES... the car goes faster in straights and twisties? You still hold on to the lighter tire?

If the car goes faster in a straight line (no impact of rotational force) and the car corners better... what good has the lighter tire given you? The bragging rights to the light tire?

Seems a bit too much of the "cutting off your nose to spite your face" way of approaching the matter.

That was my point of every post.

<Shrug> Ok.

Actually, I'm going to check out the new PZero probably.

Do let us know how you fair... would be good to hear from a PS2 owner and fan.

LSD is a Quaife ATB unit.
It works perfectly with the BMW DSC/DTC, as Birds in the UK has shown it and Auto Sport Magazine drove it and loved the feel.

I'm keenly interested in the Quaife LSD. Where did you get? How much? And since you're in L.A... can you tell me who installed it? What should I look for in hours/cost for an install?

Thanks in advance...

bottom line, 99% of tire reviewers on TR and this forum for that matter have NOT pushed any tire to it's limit.

I'd bet only 5% of forum members have been to a road course circuit.
Maybe a few more to the Drags, but you can drag on the street too.

I don't take the reviews on Tire Rack all to seriously, as most 'think they can drive', but honestly can't.

I've been to the Drags and to track days with alot of 'Monday Morning Quaterbacks' that show up with all the glitz of being Micheal Schumacher and I end up lapping them my 4th go around at Streets of Willow.

I would bet money on the fact that anyone tha buys an RE-01 now, still won't push it to it's limits or past what a PS2 or Conti2 or General Exclaim is capable of.

So, in my mind, my opinion is the only one that matters pretty much, as I know my driving style and ability.

Talk to Harleigh at Autotech in San Juan Cap about buying a Quaife ATB LSD for our 335i.

There is another tread where someone asked Gary at TR about the new PZero and he said 'I don't really know much about that tire'....... So take TRs info with a grain of salt as well.

off to work.

Below is what I posted a week ago in another thread. RE-01R is not in the same category, thus not tested in Sport Auto. In the Sport Auto test the new Pirelli is a full second faster than any of the competitors, so if someone of these tires would be compared against RE-01R, it would be the new PZero.Notice that for some reason F1 Asymmetric seems not to be available in US. In Europe it is slightly more expensive than the old GS-D3.

"I just typically browse through the tire tests, like today, in the current magazines, without buying them as I don't have any need to replace my Potenzas at the moment. This time I took a few minutes as you asked the info and as far as it stays in my memory, here it goes:

Sport Auto 5/2007: Pirelli P Zero was clearly the best tire. Goodyear Eagle F1 Asymmetric (which is better than Goodyear GS D3) was third. PS2 was 5th out of 9.

Powercar 2/2007 did test P Zero Nero (older version) so Pirelli, Vredestein, Goodyear and Conti SC3 were on the top. PS2 was 5th out of 8. PS2 was the most expensive, in this test so no reason to purchase.

In both tests F1 was better than PS2. SC3 was clearly better than PS2 in Powercar, but slightly worse in Sport Auto.

PS2 position was slightly better in dry tarmac than in wet, but however it was not the best tire in dry either. In sport Auto test P Zero had the best grip in dry.

RFT's were not included in these tests. However, generally RFT's are better in dry and worse in wet. If you are interested in dry tarmac performance here are some figures for you from a Sport Auto last year:

Handling dry (2770 m track):

Potenza RFT: 1,17,0 min
Potenza non-rft: 1.19,4 min
PS2 RFT: 1.17,4
PS2 non-rft: 1.17,8 min

(This data is the main reason for me not to ditch my tires )

Unlike what I said earlier, it seems that the new P Zero is available.

Notice also that the whereas GS-D3 was a good tire, its successor should be - and now in the tests has proven to be - extremely good. This is Goodyear expectations from earlier this year:

"Goodyear has launched a new tyre designed to replace the much-vaunted Eagle F1 GSD3.

But, while the old tyre’s symmetrical tread design was key to the product’s success, Goodyear is expecting the new product to succeed exactly because it isn’t. In addition to an asymmetrical tread design, the Eagle F1 Asymmetric features an asymmetric casing construction designed to reinforce one side and squeeze more grip from the tyre. Goodyear representatives told Tyres & Accessories they were gearing up for more award success following the introduction of the ‘Active Cornergrip Technology’ into the design of its latest tyre."

So at the moment it seems that the best tire out there would be Pirelli P Zero and the new Asymmetric Goodyear could be considered as well."

the tire size on the tire you want us to try DOES NOT come in 255/35/18 which us the stock size on my 300i sport and thousands others. What is so confusing about what i say? You asked why more people here dont use it and I gave ytou the best reason I can think of. She had the 050 on her car and the grip was good but the grip was better when I had put BFGoodrich KDW2 and is even better with the PS2. Sorry for using the word luck it really seems to bother you.
