Garage List
Question Run flats and spirited driving

BIMMERPOST
     Featured on BIMMERPOST.com
After having my car for a month and change and weather getting better, potholes being filled, I've finally started to put the car in Sport mode and drive this car like I drove my Audi TT (well almost as this GCFW is twice everything of the TT)

One thing I've noticed quickly is the grip, or lack thereof of these run flats. I mean I do not get any sense of security going fast and turning no matter how shallow the corner. Not that the car is soft, it's hard but I don't have confidence in the tires just yet.

For anyone in the NY, NJ and CT, you all know the Merritt Parkway, a pretty fun drive. I'm wondering if these tires are up for that road (two lanes for say 100 miles, curves, hills but fun, fun, fun)...

Is it just me, the tires (only 2400 miles thus far), maybe not warm enough or am I expecting too much?

For the record, I'm not racing or anything but I cruise safely anywhere between 80-100mph weather and roads permitting.

Thoughts?

you need to get used to it. No I had no problem with those tires (with my previous 650i M-Sport package) at all even at curves turning very fast (over 80) in Sport+ mode traction off. Sometime I had your feeling while my M6 running in MDM mode, but now after about 7k miles I'm fine. I believe the issue that you are referring is not about tires since you are comparing the big heavy powerful BMW 6er to small light Audi TT with half power. watch this video. I think you are talking about what happens at 5:00 and car skids a lot. yes this is a big car but lots of fun and pretty stable after DSC does the job.

JUST got home after ditching the factory Dunlops RFTs (after only about 12k miles) and replacing with Hankook V12 EVO2s. These are the new EVOs that just came out. Had to wait about 3-4 weeks.

WHAT A DIFFERENCE. I hate the RFTs more than ever. If I get another 6 series I'm changing out the RFTs at delivery. Gone is the pounding over tar strips and broken roads. Gone is the rock hard feeling of over inflated tires.

It's too soon to comment on the EVO 2's performance as I need to drive a bit more for the mold release and mounting grease to dissipate. But all signals point to massive improvement and feel. I'll report back soon to the OP regarding the comparison to the RFTs.

In others news my father just got his 2015 CB 650 MSport GC yesterday and already bent the 20 inch wheel on a pothole on 684. Thankfully he got the tire and wheel protection... -.-

Your so right Bonz, when changing out from RFT on how the despise level for the Run Craps exponentially doubles or triples. I'm really looking forward to hearing your review on the Hankooks.

Congrats !!
