Hi,
Recently purchased a 2012 330d E92 M Sport and the tread on the rear tyres are shot so they need replacing. The car is currently sitting on Bridgestone Potenza RE050a which I think came with the car originally?
I've been advised by BMW that should stick to these run flats as the car has been designed with these in mind and it may affect the handling a cause further problems, however I'm pretty sure they might just be making this up? I'm used to driving an MR2 roadster so I don't really feel the hard ride much and I've been told that safety and ease of run flats outweigh the cons.
However upon searching the internet I've noticed quite a few people are changing for non run flats and just carrying a bottle of sealant around with them?
So what should I go with? The fronts still have a bit of life in them so do I just replace the rear with the Bridgestone run flats or do I change the whole lot for something different?
My tyre sizes are:
Front - 225/35R19 88Y
Rear - 225/30/R19 91Y
Sorry if this is is a stupid questions but I've heard mention of getting XL tyres for this kind of car? Is this something I should keep an eye out for when looking at new tyres, I don't really know much about tyres as with MR2 I've always just got the previous ones swapped out for the same so sorry if this is all obvious but I really want to get the right tyres.
When doing searches, Michelin Pilot Super Sport and Goodyear Eagle F1 Asymmetrical 3 seem to come up a lot but I don't know how suitable they are?
Thanks for your help!

The car will have been designed with runflats so yes, the statement is correct. However, I'm yet to hear of anyone complain about the positive virtues of standard tyre vs runflats tyres when making the change.
The important thing to note is not to mix them. The handling balance change can be quite drastic so if you do want to change to standard tyres, do all four.

Be interesting to know the view of your insurers.
If the manufacturers spec is that a specific type of tyre must be used - the runflats in the OP's case - would they regard the use of 'normal' tyres with a can of sealant as is common on many cars as a modification that should be declared with potential financial consequences in the event of an incident?

As long as the non-runflats match the size and load rating specified (and are E marked), the insurers can't say anythingIf the manufacturers spec is that a specific type of tyre must be used - the runflats in the OP's case - would they regard the use of 'normal' tyres with a can of sealant as is common on many cars as a modification that should be declared with potential financial consequences in the event of an incident?

Wasn't the e90/92 offered from new with non runflats as a no cost option? Non runflats will be fine, I've fitteds them to my z4 coupe and it made a big difference to comfort, road noise and handling. I think runflats have improved over the years though, newer ones might be better.
I'm not sure the general e9x had a non-runflat option, the M3 certainly was non-runflat and no spare, and the M135i / M140i come with non-runflats by default with runflats as a no-cost option.I've no comment on the runflat / non-runflat option, but I will caution this:
Whilst in Donegal last week I had a bad puncture on the O/S rear of my X1, wearing OE Pirelli Cinaturo Runflats.
Given I know the cost of new Pirellis on the mainland, I decided to have the local tyre place fit the cheapest non runflats in the correct size.
Despite the Pirellis that came off having approx. 1.7mm of tread, the brand new tyres that went on are nothing short of lethal... in 9 months and 20k miles on the Pirellis I'd never seen the TC light, on these cheap tyres it's flashing on every bend and roundabout, even in bone-dry conditions... I've never known anything like it.
In short, whatever type of tyre you opt for, buy a decent brand, cheap rubber really is a false economy.
