Hate to resurrect an old thread, but I was looking at my tires the other day, and realized that I'm going to be due for a new set VERY soon. Currently, there are a set of Goodyear 205/50 R17's on my 128i. Has anyone played with tire sizes for this? Need to do this before the car becomes due for inspection this year.

You have four wheels the same size(widths) ? Or do you have the sport wheels with a staggered setup ?

I'll assume you have the square, same width setup. So you have 205/50R17's on all four corners.
You could also go with 225/45R17s on all four corners as well. Go visit Tire Rack for more tire research. I really LOVE the Michelin PSS tire. In the wintertime I have Michelin Alpin's on my "other" BMW and really love them too.

You would be correct. 205/50ZR17's on all 4 corners. I was looking at TR, and they suggested 205/50R17 for the front, and 225/45ZR17 for the rear..
I need to do this soon.. Brakes need redone, and I'm undecided there (what to upgrade for now), and I need new tires while I'm at it. All this has to be done before inspection is due.

I'm in the same situation. My all season RFT's are at the end of their useful life. I've been running non-RFT Ice-X snow tires in the winter.

I'd like a more performance oriented summer tire (square setup), but I'm hesitant to go to non-RFT performance tires without replacing the sub-frame bushings.

I don't see any mention of replacing the sub-frame bushings in this thread, so I'm wondering if the Pilot Sports would benefit from the stiffer bushings or whether the PS3's are stiff enough that it isn't a concern.

At first I just replaced my RFT's with non RFT Michelin PS3's. The car handled fine. There is a little bit less initial turn in response - like I posted. And after a few months.... yea... the rear axle felt like it was held in by rubber bands. This was really more noticeable bc of my SW stage II tune than bc of the tires. So I also upgraded to the M3/1M rear subframe bushings(RSB). I am happy with the way the car handles. Although next on my List of to-do's are new shocks and springs. Its really a deep rabbit hole. One thing(mod) turns into some other mod.

Really... getting rid of RFT's was the best thing I could do, for an improving the driving characteristics of the car. The tires felt like they were made out of rubber as opposed to the hard as rocks(and heavy as them!) stock RFT's. RFT's felt/drove like square blocks instead of rubber tires. You can really notice the difference even on low speed small bumps.

I finally decided to go with Michelin PSS's and did the Stoptech drilled and slotted rotors along with Street Performance pads. So far, I'm supremely happy. Wasn't aware of the need to change out the bushings for non-RFT's.
I also went and got the MyCarly app with BT connector, and made a few changes.. But yeah.. I'm bitten.. What mod to do next? I REALLY think I want to change out the headlights for projectors with angel eyes, and HID's, then worry about the tune, bushings, etc. It handles REALLY well now.. and SO much quieter!!

+1, I just did the same and best money I ever spent. Now I've got some almost new RFT to throw up on the classified section.

I went with PS3+ A/S and I stuck with the sizes that came on the car and did not increase to 225/255.
