320si - From Bridge RE050A RFT to Pirelli PZero RFT?

Dear forum members, I need your help.

I have a 320si (it has an M-Sport pack) and since it left the factory back in 2006, it still has the same stock tires on. I know...should have changed them long time ago, but they have only done 30.000km.

So I am thinking of dropping the stock, stiff and uncomfortable RE050As and going to PZero Pirellis runflat. Dropping runflat as a whole, is not an option.

Tire sizes are the following:

Fronts: 225/40/18
Rears: 255/35/18

So my question to the forum members is, does anyone with an M-Sport suspension on an E90 went from stock RE050As to the aforementioned Pirellis?

How is the ride compared to the B'stones? Handling? Braking?

Would you recommend them?

Thanks in advance!

Hi,

I asked this question a while back, overall, the Pirelli seems to be much, much better than the Bridgestones, and perhaps better than the Michelin PS2 ZP.

I was about to get them, but my problem was that a)they're an old design (not to say that they're bad because of this though) b)Pirelli was screwing me big time, saying "we might get them.... or maybe not", "they may be in production in 2 months, or maybe not..."

I didn't want to ditch RFTs at first, but in the end I did - I'm running Goodyear Eagle F1 Asymmetric 2 in stock sizes, XL rated. I love them! Much more grip than the potenzas (it's phenomenal, put your foot down in a corner, and no DTC, nothing, just straight power!), more comfortable, and more stable at higher speeds... with the RFTs, at 200 kmh hard braking, the car would feel nervous, swaying from side to side from imperfections on the road... With the Goodyears, you can slam the brakes hard and hold the wheel straight, and the car will go straight...

Hm...interesting.

I'm not facing any issues with the brakes, eventhough the tires are REALLY REALLY old and have dried out. Slam on the brakes and the car goes straight...no twitching.

I have had the Goodyear Eagle F1 Asymmetric on my old 120i. I liked them, but I want RFTs.

Do you think the Pirellis have a better ride than the B'stones?

Not sure about that, I was only concerned with grip... search for my threads (my user name), maybe someone commented.
