I wonder why they tested the previous generation of Dunlop Graspic DS-2?
I just bought a set of Graspic DS-3 for our Outback VDC which are the new generation from Dunlop and are supposed to address the lower scores of the DS-2 in the dry/wet handling and braking departments. Haven't installed them yet to see how they fare. |

The one's I got are made in Japan, specifically: EU --> SUMITOMO RUBBER INDUSTRIES, LIMITED --> TOYOTA --> AICHI PREFECTURE --> JAPAN EU is the first 2 digits in the serial. |

When was the DS-3 introduced? I'm pretty sure CR makes a point of buying all their test items off the shelf, and not accepting anything direct from the manufacturers. I also assume that their tire testing for the current issue would have been done last winter, so that means they would only have had access to last year's tires. |

Anybody care to explain how they come up with their scores? The number is meaningless without how they got there.
What I want to see how is long it takes to stop/start on specific surfaces. |

How is it possible that after electricity has traveled through hundreds of miles of power line then hundreds of feet (or yards) of romex in our home, that changing the last three feet of wire with something exotic, expensive (cool looking, and packaged in a pricey box) is going to make a difference?

Good point, they were only introduced this year. Wonder why they results are only coming out now? Anyhow, I'll see how they are in a few months. |

+1. Where were the tests done too? Montreal? Calgary, Colorado, etc. |

I find some of CRs tests and reports frustrating because, in the case of winter tires, there are "winter tires" and then there are "performance winter tires". Also, there are several different winter tires within each brand, eg. I am getting the Blizzaks LM-60s for the BMW, but the CR report only lists the WS60s. On my previous car, had the Dunlop WinterSports 3Ms, which were a performance winter, and I found them quite good. They are not listed in the test, only the Graspic DS-2s (which, I think, are older?). Anyway, avoid the Hankooks...!!!  And treat the CR info as just another piece of the puzzle, not the be-all and end-all. |

My mechanic sells Dunlop tires.
DS-3's came out this year. According to my mechanic, he said the new DS-3's are superior to the DS-2's as between the sipes, when it makes contact with the ground they open up and there are sipes inside (sipes inside the sipes?)
He confirmed that Goodyear owns Dunlop just like Michelin owns BF Goodrich. (which is why he doesn't charge me for rotations or changeovers to winter tires as my all-seasons are Goodyear Assurance Tripletread).

We've tried 3 different ones, and they were all horrible...only slightly better than an All-Season tire. I've read tests that confirm this...(maybe at TireRack?) |

Goodyear bought 75% of the North American and European part of Dunlop from Sumitomo. Sumitomo still owns most of the Dunlop name in Japan. The DS-3 tires I bought were made in a Sumitomo plant in Japan. Doesn't really matter, just a point of interest. BTW, we also have the Tripletred and are quite happy with them, they are a well built tire. |

Tire Rack rates the LM25 6th overal out 0f 14, and 8.9 out of 10 customers would Buy Again. As compared to only 8.2 would "buy again", the top rated Michelin Pilot Alpin PA3.

And it even felt as "sporty" as the LMs in the dry. |

The 401's we had on the van just turned real awful last winter despite the amount of tread still left on them. Should have used them as the summer tires  And the LT tires on the Pathfinder were not that great either. |

Ok....something is seriously wrong here. I just checked the prices for the General's at Canadian Tire and unless I am mistaken, the price has jumped over $30, depending on the tire size. |

The Tire referenced in the CR report is the Primacy Alpin PA3 which Tire Rack doesn't include in their survey and not the Pilot Alpin PA3,s which Tire Rack does have in their survey. As neither of the tires you refer to are covered by the CR test originally mentioned it maybe deserves its on thread. |

No love for the Hankook Icebear. It's good that this will be their last winter on the Volvo. I did notice some deteriation in the grip at the end of last year. At 8/32"s. Honestly they aren't as bad as CR makes out. Last year they rated the same model a red circle for ice traction. Now it is a white circle?
Anyhow my new set looks like it will be the Continental Winter extremes. |
