How are exactly non-RFT tires better at handling ? They have softer sidewalls which flex when turning therefore slowing car's response to any steering wheel movements.
On the other hand RFT tires have stiff sidewalls (to support car's weights if air pressure is lost) which make the car handle like it is on rails: all the steering inputs are instantly and telepathically translated into change of direction with no delay, no slop and no "squishiness" common in non-RFT tires. Before my M235i I had 128i with sport package equipped with RFT Bridestones and I can confirm it handled better, felt more planted and "locked in" than my current car. |

Rft feels like you're riding on concrete. Sidewalls are stiff but very poor feel. Having better shocks/springs will feel like its on rails. I wouldnt want the tires to feel like that, rft bounce too much and not gripy as non rft high performance tires

also you can always increase psi if you want stiffer tire but you can't soften an RFT |

The RFT tires also easily bends over under intense cornering (had first hand experience @ autox events). Its common for people to run super high tire pressures (~40 psi) at the autox/track if they have RFTs compared to low 30 PSI for non RFTs just so the sidewall would not give out. If the sidewalls are so stiff as you claim, there would be no need to run such high PSIs. RFTs have no place in performance driving whatsoever. PS: I've had the Bridgestone S001 RFTs and they are absolute garbage compared to actual performance non-RFT tires. Not to mention they are expensive as hell to replace. |

All you have to do is run a slalom with run flats and hear that tires squeal and lose traction. No way run flats are higher performance.

I'm also stuck in this boat unfortunately. Going to keep the pirellis on through winter and the first few thousand miles for break-in anyhow. Springtime will be looking for options. |
