Michelin PSS Star vs no star
What is the difference between a Michelin PSS non-star and a Michelin PSS star? Is the rubber compound different or is it just the tread width that is different? I can't believe that a Michelin made for a Porsche is less sticky or more sticky than one made for a BMW. The tire made of the Porsche, same size of course, is wider than the one made for the BMW.

Lots of manufacturers have their own special hallmark they put on the tires they assist in development. Bentley has a "B". Porsche has N0. Ferraris put a K or something like that on theirs. Bimmers get a star. Are they really any different? Maybe, maybe not but as long as the size is the right size they ought to work. |

Truth is, no one outside of BMW knows. Most of the time it doesn't appear that BMW makes big changes. However, if you look at the Corvette version of the PSS, I think they might be a more aggressive tire. They have a lot of reports of cracking in low temps which I haven't seen with the normal or BMW PSS.

I'm reviving this, because I'm hoping someone has a better answer. Because I'm a little dumfounded right now.
Long story short, I had to replace my right rear tire after only 800 miles. Went to the dealership to have them replace the tire and assumed that the tire would be a PSS with a BMW Star on it. Long story short, It's not. In fact it has "MO" on it, which I found out is Mercedes. I've been doing a bit of research in Michelin's site and it appears the BMW Star version weighs in at 26.2lbs vs the Mercedes one weighing in at 24.8. To me that tells me there's something in the BMW PSS that's different. Initally I wasn't going to fret over it much, but I'm going to have to say otherwise. It's basically like running a different tire on the wheel. Take a look at the table: http://www.michelinman.com/US/en/tir...tail-sku-table |

I'm just surprised a BMW dealership has not installed a BMW-approved tire.

I'm in the midst of having the discussion with the dealership. Yesterday I had the run around that "its the same tire, the tire with the part number we use, its the tire we get from the distributor, etc. etc." Well, you're distributor is messing up. |

Another confirmation that dealers are just clueless.
