You keep harping on about that, there is nothing in my experience with the S.drives which supports that. I'm questioning the data you're working from. I have first hand experience.

 

I've been trying to quantify the ride quality of these tires. In comparison to the S.drives, the DS-G3 just feel square. I came up with some data using the iPhone ap "Vibration". It measures the vibration the iPhone is subject to and plots vibration vs frequency. I messed with the results a bit (using a weighting function, supposedly of the human body's sensitivity to vibration). Then plotted the results, they look like this:



To make that clearer, I plotted the low end relative to the S.drives, that looks like this:



That's showing me the DS-G3s are significantly rougher, especially in the frequency range you're most sensitive to (about 8-16Hz).

 

Isn't there an issue between German made GS-D3 and China made GS-D3? I believe I read here that someone had had both and the China versions had inferior grip.

What is replacing the GS-D3?

 

I've heard bad things about the Chinese ones, all mine were made in Germany, so I have no experience.

Nothing obviously in that size. I'm looking at other brands.

 

The GS-D3 is being replace by the Goodyear Eagle F1 Asymmetric.

I'm trying to decide between the new F1 and the Sumitomo HTR Z III.

 

The F1 Assymetric sounds like a great tire, but they don't make it in 16".

 

question it all you want. it's as scientific as one can get - read the article. blind test. S.Drives are worst in test. I'm sorry that offends you.

a bit of anectdotal experience about why braking matters - I'm running 265/35/18 RE-01R's on my car and it's got Brembo's. During a brief moment of inattention while looking at the radio last week on a long stretch of road with no stoplights, I looked up to find traffic at a dead stop. Foot to the floor panic braking and the car stopped with plenty of room from 65mph. The cop directly behind me had to swerve into the next lane to avoid hitting us all. 35ft longer stopping distance would have = major damage.

The fact that I got into the ABS means I could have had MORE tire on the car as braking power exceeded grip. This is with an RE-01R which is one of the best tires out there....on par with the F1 Asymmetric. The cost of my deductible alone far exceeds the extra cost of putting top-notch rubber on your car.

 

EVO is no more unbiased than is CR. Their testing may be thorough, methodical, and interesting but it's far from scientific (as are most tire tests). You run risks of bias by putting blind faith in a solitary supporting reference -- particularly when it's describing two year old products.

Those who like one tire or the other like them. The bickering in this thread is amusing, but I reckon no one's opinion is going to be changed.

 

of those who consult testing before buying tires, I'd guess most look at TireRack.com. Apparently that's good enough for some and counts as 'credible'.

 

You do have a good point there...they certainly seem to be held up as the standard here on NAM.

 

I'm on my second set of GS-D3s. First were German, Second Chinese. Honestly both have been the best all around high performance tires I've ever had on a car. The German set seems to have lasted a bit longer, but I only auto-xed them, while the Chinese set have been to driving school at Mid-Ohio. I'm gonna miss them if Goodyear drops them in favor of a new design. Might just have to buy another set while still available.

 

/\ but the F1 Asymmetric are better in every way. I've owned two sets of GS-D3 and one set of Asymmetric.

 

Have you tracked your Asymmetrics?

 

I've been looking at the Tire Rack test data. I'm using the Michelin Pilot Exalto PE2 as a reference point because I have a set. Problem is that it was tested in 2008 with a 2008 BMW E90 325i Coupe. The Eagle F1 Asymmetric and several other tires were tested in 2007 with a 2006 BMW E90 325i Sedan. I wonder how the two model years compare? One faster, quieter, stop quicker than the other?

Is the PE2 really faster around the track than a GS-D3, Pirelli P Zero, Michelin Pilot Sport PS2, Potenza RE050A Pole Position, or Yokohama S.drive? Me thinks the 2008 Beemer must faster than the 2006.

 

no, I had A048's for that. The EVO mag article I posted shows track results (of course not vs. the outgoing GS-D3).

 

Anybody have any thoughts regarding the Bridgestone Potenzas or Goodyear Triple Treads?

 

That doesn't offend me, what offends me is your bad science. We have raw data which conflicts. Good science would be to try to work out why the data conflicts, bad science is to ignore one data point and insist with no reason that the other data point is more significant.

I'm trying to work out what the difference is, you're just insisting the magazine is right and everyone else is wrong.

 

By the way, I got some Michelin PE2s and added them to the comparison: https://www.northamericanmotoring.co...ml#post2779845
