Real world MPSS vs MPS4
Featured on BIMMERPOST.com Now it’s winter, I’ve noticed pulling out of junctions, I get wheel spin in the rain, even being gentle with the power! So tonight I took my wife’s car out, not only is the ride so much nicer but almost no wheel spin, even when flooring it! I’ve heard the Supers are more of a summer tyre, but are they really that much worse, am I imagining it!?😂

I had the PSS tires on my car until just a week or so ago. I noticed that when cold, they didn't grip at all and I'd routinely have the traction control kick in when cornering at slow speeds until they warmed up. They didn't seem bad in the rain, though. Have you noticed a difference after you've been driving a while vs. when first going out?

The rubber compound in the super sports gets harder below 40 degrees and at 20 degrees it can actually crack the rubber. Don't drive in the cold with them.

The PS4S is the replacement for the PSS and Michelin improved the overall performance of the PS4S so not surprised it’s out performing your PSS. I find the OS4S side wall to be a little softer than the PSS but the PS4S still outperforms the PSS in summer handling and grip.

It was after I went to square 255/35-18 PS4S' for my M240i that I discovered the OEM 245/35-18 PSS tread widths of 9.2" were wider even than the 255 PS4S at 8.8". That came as a bit of a surprise. Had I done proper research, I would have chosen to put the BMW Star Spec 245s on the car.

That would yield the wider tread and, I suspect, a compound somewhat better-suited to the car for which it was spec'd. I'm not that picky on the street, though, especially in a region where the back roads are generally pretty narrow.
