My '22 with the ZTK package came with Continental Extremecontact Sport summer tires.

Hold up, from the factory, BMW gave you staggered All Season tires. Interesting.

2023 staggered setup on mine with 245/255 Michelin Pilot Sport 4s...after running both Bridgestone & Pirelli on my previous G20 M340, I can honestly say, Michelin beats them hands down in every category - ride, cornering & braking.

The only potential problem I may have are with the fronts, which are an odd width 245, quite close to the 255 rears, so not that much of a stagger...

Anyone tried running lower width up front? (225 or 235?)...otherwise I may be tempted to upgrade the rears to either 265/275

'24MY RWD w/ZTK package just delivered came with Michelin Pilot 4 S *

245 front/255 rear

Will likely move to 265 or 275 in back when these wear out. The rims are definitely wide enough to handle wider tires - the tires almost look too small for the rim width now.

That is very odd - every one that I have seen with ZTK had the Pilot 4 S * tires which are actually very special tires made for BMW M cars. Did they come that way from BMW or did you buy it used?

I am 99% sure that my car was a BMW Press car. I bought it with 500 miles on it in February '23 and it was a '22 BMW M240i (has every factory option)and only ever registered to BMW of North America. So there's a good chance that they changed the tires at some point but I don't really know.

I was considering getting 265s for the rear and moving the 255s to the front but it doesn’t look like Michelin makes a PS4S * spec tire in 265/35/19.

That is good to know.

If we don't track our cars, I wonder if we would notice any difference between the more common PS4S VS the special PS4S*, especially on a RWD car. We might even notice a slightly quieter ride with a non-track oriented tire.

For city / highway driving I really doubt that I would notice a difference.

What makes you think the PS4S* is a “track oriented tyre”?

The ZTK package is a track oriented package as opposed to a street oriented package. Those tires only come on M cars and baby M cars that have the tire/wheel/track package.

If they aren't track oriented, why would they not put them on all the cars?

Everything that I have read about these special * tires indicates they were developed for drivers that would track their cars. I see no reason why they would develop a special tire for street use if it did not have track advantages.

If you just want to argue about semantics, go ahead but I will stand by my assertion that they are track oriented.

Wow. Take a breath thinkerbell. No one’s arguing.

Not agreeing with you, but not arguing

They work with tire makers all the time and for just about every model to optimize comfort or handling. Including the crappy Pirelli Cinturato runflats they slap on nearly everything, which carry the same star symbol. All the "*" means is it's a BMW Group part.

The OEM spec PS4S are nice, but they don't feel radically different than the normal ones (I've had both).

On the contrary, by this response it is very obvious that you are trying to pick a fight.

my 2024 came with 797's and 225/40/19 Bridgestone Turanza LS100a rft

Looking to get some PS4s or Cont extreme contact sport 02

So square 225 setups have x8 wheel width all the way around?
