Hey all,

Unless I'm missing something here, it looks like Michelin is finally making the PSS in the size we've all been wanting for a long time!!

Think those are run-flats.

These are ZP (Zero Pressure) rated (run flats)

Yes, those are run-flats. Used for original equipment on the front of a ZR1 Corvette.

Thx Ben, I was also curious about running the OEM PSS 255/275 for the F80 M4 on the E90 M3. I know they're supposed to be designed specifically for the M4, but given the similarity in weight distribution, similar suspension designs, similar loads, and Front engine rear drive setups, if the M4 PSS would be taking advantage of a better, more M-specific compound that may also benefit the E90M3. Any insight is appreciated. Thx in advance.

The auto makers and tire companies are not very forthcoming with what changes are made for an OE variant of a tire. Sometimes differences will show up in the tire specs that they are required to report, but beyond that they don't give much clue as to what, if anything was changed.

In the case of the F80 PSS, it doesn't look like there's much difference to be found in the specs. Doesn't mean there's no difference in the tire, but the change would be fairly subtle.

I'm perfectly happy to be proven wrong on a case by case basis, but my general rule is this: if you don't have the specific car for which the tire is OE, getting the OE version is unlikely to give any specific benefit.

I wouldn't worry too much. Didn't the E9x M3 come with OEM tires from three different tire companies (Continental, Pirelli, and Michelin)? I imagine there is quite a bit more variance from tire company to tire company than within the same model of tire offered by the same company.
