How does E92 perform without RFTs?

I'm curious to know what the effect is of removing the run-flats and replacing them with traditional tires. I can't say that I hate the RFTs, but they do make the car's handling feel a bit more insulated and synthetic.

I had Michelin Pilot Sport A/S 2s on my E46 which were just incredible. If I do ditch the RFTs, I'll probably go back to them. Does the car handle or behave differently in any negative way without the RFTs? Does the TPM system still work without them?

Every aspect of my car's ride and handling is better with non-RFTs (OEM size for winters and +1" for summers). TPMS works the same, it's on the wheel and doesn't care about the tire kind. The only downside (my choice) is carrying a compact spare in the trunk.

Mine were first-gen/2007 RFTs, perhaps they've gotten better, but I ditched and didn't look back.

Just be aware that if you're leasing your car, you'll need OEM RFTs in place for the return.

I've had non-runflats on my E92 for 3 years...no problems, better ride, and better handling.

Simply put, considerably better. The rider is quieter and handling is not affected at all.

I just ditched the runflats that came on my car (Bridgestones 18" on 193M wheels). Replaced with Hankook V12 evo tires (19" on Style 269s).

I realized the RFTs are hard as a rock. Bumps are soaked up so much better and you get an even better feel for the road. The car sticks to the road, handling is improved, quieter, just improvement all around. Not a single thing I miss about the RFT save for the fact that no spare was necessary.

If you lease, take the RFTs off and keep them, just put them back on when you return the car.

Dramatically better without RFTs. The instant turning response you get from the stiff sidewalls on the RFTs is nice, but isn't a "true" handling characteristic. Overly stiff sidewalls negatively affect the side of the contact patch under actual cornering - plus in corners my car actually used to "skip" because of bumps with the RFTs.

I'm by no means a tire expert but my change to 235/40/18 (front) and 265/35/18 (rear) Hankook ventus v12s (yes, cheap tires!) has produced a much more comfortable ride, with more predictable handling characteristics. Wish I had switched long ago...

Planning on picking up the compact spare kit for my trunk as well.

Note - I have very little direct experience with the newer RFTs - mine were the old brigestone REO50AII...

I also have the Hankook Ventus V12, paid $614 for all four. An excellent, cheap tire...

Most non-RFT's ride better and are quieter. BUT, you lose steering response and some of that wonderful "planted" feeling the RFT's offer.

If the roads I drove were in better shape, I'd consider going back to the RFT's, but they are expensive, difficult to repair and much heavier.

I also replaced with Hankook Ventus V12 18"; however, at high speed (160KM+) I found my RFT were more stable.....

We strongly suggest Hankook Ventus V12 as well. They are the best bang for the buck. Also gives good grip and nice handling. The tire threads also last longer. As for the ride comfort, you can definitely tell that these are softer and feels better compared to thick RFT sidewalls.

My RFT's feel planted enough in a corner, so long as that corner is baby-butt smooth. Any imperfections and the car gets twitchy. Looking forward to being non-RFT.
