Anyone know why tyres with the approved star cost up to £20 more than the same thing without it?

BMW probably get a rake-off - but they will probably claim that such tyres are specially checked tobe fit to carry the star.   If you believe that, you must also believe in Santa and the Tooth Fairy . . . .

That was my immediate reaction too but it seems my insurance company takes a different view. No star= modifiied tyres = we cannot insure you. So sayeth the person on the end of the phone!

Are you using BMW insurance? If so, they have a vested interest in the use of OE parts.

For the more exotic models however, it is possible that BMW are doing the same thing which Jaguar did during the 'seventies, when the six cylinder and V12 versions of the E-Type, XJ saloon, and XJ coupe all used a common size and type of Dunlop tyre - but each of the six variations of model and engine type used a tyre of subtley different  construction, although they all appeared to be identical.  The exactly correct tyres, marked with with nothing more than a paper label, were only available from Jaguar dealers and were priced accordingly.

Of course, BMW's star may mean that there are differences in tighter tolerances on concentricity, lateral run-out, and balance, which would be important to those few heros who use all the available speed - but there are precious few of them.  For most of their cars this 'approval' will mean nothing.

Hi Mike

I bought my last BMW * tyre off the internet. I priced the same one at ATS and it was £50.00 more expensive. The one I bought was delivered and fitted at ATS !!!! not sure how it works but it's certainly a cost saving to buy this way and its fitted correctly as well.

If that was Blackcircles, Halfords under cut them by £20 for Contisport 5 RF's.

Ok.. from a Tyre company POV..
 
Tyres that carry a specific homologation marking, e.g. * = BMW, "N" = Porsche, MO= Merc etc. have been developed by the car and tyre manufacturer to optimise the interaction between the tyre and the vehicle.
 
Michelin/BMW have worked together for decades (and others have too..). If there is any reason why the tyre is slightly more expensive, it is primarily a supply and price difference. E.g. we don't charge way more for a homologated tyre than a standard one. But it can be very different beast
 
For example when we worked on the current M5/M6 with BMW M, we ran through some 2000 test tyres and iterations until BMW were happy with the finished product, which then then "homologated" into the Pilot Super Sport *.
 
Now, you can run a vehicle on a non * marked tyre, but in some instances it really is strongly recommended.
For example, we can tune: compounds, casing (constructions) and dimensions. So for some cars if you move away from the homologated tyre a standard tyre might not work on the car.
The vehicle manufacturer isn't doing it to make life difficult for you. Its often the only way to ensure the vehicle performs to its full capabilities.
For example Porsche strongly recommend the "N" rated tyres and it can affect their warranty if a non homologated tyre is fitted.
 
Should you fit * tyres? Where possible, yes.
It really comes down to the driver. In Germany you'd struggle to sell a relatively new BMW used if the tyres were not * marked fitted...

Thank you for your input Tyre Expert, it's always a pleasure to hear a conglomerate's representative speak in public.

Halford's fitted non-starred Contisport 5's RF's but corrected their suppliers error yesterday. I thought I was imagining things until I read TE's explanation. The starred version felt in tune with the suspension and absorbed irregularities vastly better. In fact I felt I had normal tyres on the front. The tyres that came off originally were very old BMW Bridgestones. I can't wait to get the rears changed for PS2's as no Contis in that size.

I'm looking to find 4 tyres for my soon to purchase BMW 382 17" alloys. BUT all the tyres that are * BMW are Run Flats,   and I don't want B****y Run Flats.

I have tried all sorts of sites lots of tyres but as soon as you say BMW I get shown run flats and nothing else.

So what is a guy supposed to do. !!!!!!!!!!!!! I certainly will not buy run flats.

Dependant upon the sizes, you may struggle to get a non run flat * marked tyre

after all the * mark is for the OE developed tyre, and a lot of OE (original equipment) is run flat, so for your car the only approved tyres would be what they left the factory on

You may be better going for newer tyre patterns/models that aren't run flat or * marked

Hi
I recently changed my tyres to Michelin crossclimates to give them a try, as I can only afford to run one set of wheels & tyres. Are these BMW approved & what tyres are OE * marked for my car ?.

What is the manufacturers recommended tyre pressures for the crossclimates?.
Tyre size is 205/55 R16

Regards

Out of interest, does BMW provide a list of approved/recommended tyres.
As cars age, the tyres that were originally installed (approved) when the car left the factory will at some point become unavailable.
I know Porsche produce a list and wondered whether BMW do the same?

Reading this thread one would be forgiven for thinking that Michelin was the only BMW-Approved tyre in the world!  The Z3, for example, came on Michelin, Continental, Dunlop, and Pirelli tyres.

After going from the original - and quite unremarkable - Michelin Pilot Sport* to Falken FK-451 I could not detect any difference at all, except to my wallet!  Unless your insurer follows the BMW party line, I bet there is nothing to be gained from spending money to have a little star moulded on the sidewall, not matter how many hours were allegedly spent to match the tyres to the car. 

Let's face it - the average M3 driver etc may occasionally have a quick belt up to an ego-gratifying speed for a few seconds, but most of their time is spent plodding around town or following the usual motorway procession, when a good remould would be fine . . .

If you drive like a rabid German - and virtually no British owners can or do drive like that in or out of the UK, except in their dreams - then perhaps an Approved tyre may make a tangible difference, in the real world I doubt it.  Has anyone noticed a worthwhile difference?

Mine came on BMW-Approved Continental M3 tyres. Wear rate was awful, dry grip was nothing to write home about, and wet grip was a bit scary.

Put Supersports on them when they became available in my size and haven't looked back. Price has even dropped from about £800 a set to closer to £500 Thumbs Up

What size do you have?  I thought the E36 used 215/45 R17 front and 245/40 R17 rear, both are available sizes for PS/4s.  Or are you using the older square setup with 235/40 R17 all round?

The staggered m double spoke wheels were an option on the m3 e36 3 litre coupe, mine has the original m double spoke style 22 fitted which have 235/40/17 all round.

BMW approve them under very stringent tests , Mercedes and Porsche also do the same thing approving their car tyres . Unfortunately we pay for the testing by the increased premium

Hey guys,
I've just bought a 730d M Sport 2014 and was wondering if anyone can recommend a good, independent, VAT registered BMW specialist in East London. I'm based near Stratford in East London so anywhere within 30 mins commute from there is perfect.
Thanks in advance ;)
