My Ride: On Order, due in May - 2007MY 530D SE, Silver Grey, Black Dakota, Auto, Brushed aluminium shadowline,sports seats / wheel, hi fi speakers, mats, space saver wheel and a few more bits
![Default](https://5series.net/forums/images/icons/icon1.gif)
11 October edition of Auto Express (UK) carried out a claimed first ever run-flat tyre test.
Concluded that non RFT's compared to RFT's performed worse, lost control in thw wet earlier and took longer to stop. Tested on a 3 series, Bridgestone won - the testing was at Bridgestones ?30M euro testing ground
. General view was that the car was designed for RFT's and should always use them
After advice on our forum, I ordered the spare wheel as an extra for when I ditch the RFT's in the future. Was that a mistake?

So to get back on topic, this report may be more relevant to the E90 than an E60. I have just swapped to 19" non-RFT and to the best of my knowledge, BMW has not yet approved a 19" RFT for the E60 anyway? So you cannot generalise with the non-RFT vs. RFT, it depends on the model, wheel size, etc.
@07530d
To get back to your original post, you have not made a mistake with your choice to move to non-RFTs. You do however, still have to make the right choice with the brand/type of non-RFTs though if you are really going to benefit from the change.
No doubt other Forum members who have made the switch can also advise.
Cheers

There's no doubt RFT's are getting better. My 550 came with Bridgestone RFT's and they were pretty good.

No way i'm going back to RFT! Traction in the wet is minimal and i can't figure how a non-rf tire could do worse in the wet...i might aswell start walking if it's true.
BTW i suspect there is NO motorsport that uses RF tires right?![Big Grin](https://5series.net/forums/images/smilies/imported/biggrin.gif)
Also who said that the E60 was designed for RF tires?!? So the E60 in staggered setup is what? A compromise or what?

So if RFT are better than non RFT then why don`t the F1 or rally cars use them? ![Laughing](https://5series.net/forums/images/smilies/imported/laughing.gif)

Sorry, the article was about RFT's on the current 3 series (dont know what E). Maybe it was not relevant to the E60 but the report summaries generalised about all RFT cars??

Apparently Ferrari are going to be using RFT for some road cars. The Goodyear Eagle F1 EMT.
Ferrari chooses Goodyear Eagle F1 EMT for new Ferrari F430 equipped with Runflat tyres The EMT (Extended Mobility Technology) allows the tyre to run flat keeping both high performance and safety. The new Run Flat equipped Ferrari F430 will be exclusively fitted with Goodyear's Eagle F1 GS-D3 EMT 225/35ZR19 (front) and Goodyear's Eagle F1 GS-D3 EMT 285/35ZR19 (rear). The Goodyear Eagle F1, the award winning top performer of Goodyear's high performance tyre range, is the perfect match for Ferrari's latest creation.
With its 4300cc 90 degree V8 engine and 490bhp, Ferrari's new F430 takes four seconds to reach 100km/h from a standing start and reaches a top speed of more than 315 km/h. Goodyear Runflat tyres can be safely driven after a puncture or total loss of pressure.
The reinforced sidewalls consist of an innovative rubber that bears the weight of the car even when the tyre is totally deflated and that keeps the tyre on the rim. The Eagle F1, with its striking V-shaped tread design and OneTRED technology, continues to set the standard among tyres in its class.
It has captured the top spot in key consumer magazine ratings, won several technology awards and captured top spot in countless tyre comparison tests including Auto Express, evo and Which.
