Your fleet running reports

Tyre question from my dad as I really don’t know. He wants to fit new non runflat tyres on the 7 series. It currently has nearly new Potenzas of some form but they’re rubbish.
Seems like the only decent non run flat option in BMW star mark form is the Pilot Super Sport but they must be a 20 year old tyre by now.
PS4S available but non BMW star marked for the front axle.

Given the options do you go for:
PSS
PS4S but rear star marked and front not
PS4S but neither axle star marked

Am I clear as mud?

If the RF SS’s are like the non-RF ones that come on the m2, they’re very much a summer tyre (useless <5°). PS4S’s were a far better option for all year round with very little disadvantage.

I would image they’re even worse as the tyre walls are solid but they do sell them in non RF version for the 7 series too. But yeah seems like the PS4S is a way better tyre regardless.

Does it even need ‘sporty’ tyres? Would a normal ps5 or whatever not be more suited to a big barge? - unless they don’t do them in the right sizes.

They don’t do PS4 or PS5 for the rear sizes. I think you get above a certain width and it’s automatically into sport tyres.
