Finally pulling the trigger on some new tyres for the 340 but there is £30 difference between having the * rating or not and wondering what the impact is in not having them * rated?

Thanks for your help guys!

I've got non-* PS4S about 2 months ago, from Blackcircles.

I just went for the cheapest in the right size/load, and they are absolutely fine and brilliant.

Apparently the * means nothing really, it's the BMW approval (or Mercedes is MO, etc) but the tyres are pretty much identical, no difference.
But I guess BMW will only fit * tyres so the cost is a bit more and they pass that on to the customer.

I recall reading a comment once that maybe they were inspected and found to meet BMW specs, but seems silly to me. It's a high tech speed rated tire.

MPS4S are the best tires that I've ever had. Can feel the side tread grip as you enter a curve. Amazing in rain too!

* rated tyres only really matter with X Drive cars.
You’ll be fine on standard Michelin’s

I think if you don't have X-drive it will make no difference

If you do have x-drive then it _might_ make a difference but it seems from anecdotal evidence it probably doesn't

Found this on their website?

You'll notice a big improvement in bump absorption and traction off the line if you're coming from run-flats.

Don't bother about *

* not required, I have non run flats and they are very good indeed

Agree with all said above, but depending on your BMW dealership you could have trouble if you ever have any drivetrain problems! in my case it was when i had my 7series and was having gearbox issues took the car in under approved warranty scheme
and got a call from the service manager saying that the two rear tyres are not star rated
and until they are replaced they could not proceed with a warranty claim, these tyres were actually Bentley marked tyres same size has BMW of course, so only way forward was to buy two new BMW marked rears £500, that was my experience with my dealer not saying it will be the same with others, but that is there policy regardless of 2wheel or 4wheel drive, cheers Dave

Just changed out of run flats on my 335d , I did phone one local BMW dealer to ask if they would fit P4s* and they said they would only fit like for like.
So bought the tyres from Camskil's and had a local fitters do them .

Order is in with costco now. £566 for 4 Michelin pilot sport 4s with the star rating. I'm still in warranty so just thought for £30 I'd do it for peace of mind! Really can't wait to see the difference.

Dealer was a c**t. Would not have used them again.
