Hey look, not spam.
So I need rear tires. In good warm weather, I can't hookup in 1st at all and skitter through 2nd, so grip is a factor. I'm currently on Michelin PSS, and was going to go PS4S, figured it was a no-brainer.
However, in my research, I learned that my PSS are BMW-specific (and have a little star on the sidewall to indicate as much) - never knew brands actually got their own tire molds. Anyway, they're a little stretched and apparently that's the BMW-specific part of them - they're a little skinny. For example, going from BMW-spec to Generic can be a width increase of 0.5-1".
Hopefully this pic loads, PS4S left, BMW-spec PSS on right, same sizes, both mounted:
I prefer the square sidewall appearance to the stretched one but that's not high priority. Some forum folks say steering feels lighter and the front end more vague with the PS4S (nobody is mentioning alignments, which would be another variable if it were done). This may be the kind of thing you get used to, but I really like how direct the car feels today. I'm not sure if this is due to the stretched sidewall, other BMW-specific design differences, or maybe even just the deeper tread blocks of new tires. Then again, the increased width and maybe newer tire design would let me put power down?
Anyone have experience with this nuanced nonsense?
