Run-Flat Replacement

[Sterling's X]

Hello Everyone, and Happy Holidays!

I am in the process of making a decision and would like your opinions and past experiences in travelling down this road (no pun intended). I need to decide on whether to replace 2 worn tires with the same run flat tires speced with the car (Deuler H/L400RFT); or spend a bit more to replace ALL tires with a better suited tire.

I must say that being a previous X5 owner and new to the RFT tech, I haven't been impressed with the drive. The ride feels harsh and disconnected to me. I did have the optional 20" rim on my E53, but even the winter 17" rims I had exhibited a conneted feel during spirited driving. These seem to just push.

My issue here is that I have the third row, hence no spare tire option. Is it worth the risk or carry a "slime" option to run the better handling and cheaper to run non RFT? Do I always go RFT in my situation with the third row and just deal with it (even when I purchase 20" summer/fall tires)? What have you all done?

Also, generally, how do RFT's handle in the snow? They seem like a harder density rubber to me, is this the case? Will they be just as adept in snow as a non RFT tire?

Thanks in advance to your opinions/experience on the subject. This has been on my mind for a while and I need to make a decision soon, for safety's sake. Looks like another East coast winter is coming.

Have a great day!
