For those of us with base model 128's, without iDrive/touch screen, how do you reset the TPMS after changing the wheels out for after market rims? Owner's manual only describes instructions for models with the iDrive.

You use the button and toggle switch located on the turn signal stalk.

Noob question: but what is the purpose of upping from 215 to 225 width fronts and the rears from 245 to 255?

More rubber in contact with the road = more traction. Less rotational mass = faster acceleration. +1 death to run flats. Why bother when I can press the SOS button on the roof and get a free fix-a-flat.

Less rotational mass? A wider tire, of the same diameter, would weigh more and have greater mass. Tire weights vary by manufacturer/model a few pounds, most likely when you go with a wider tire, you will have a heavier tire (of course RFT vs non-RFT will make a difference in weight, if that is what you meant by less mass?).

I am really leaning towards getting a set of PSS for the summer. I have RFT, which i used this winter in northern VA with few issues.

relatively speaking, which tires the RFT or the PSS is "Better" for cold weather or snow?

I'm wondering if i can use RFTs in the winter because we get very little snow here.

Definitely would recommend it! I can't tell you how many people have bought wheels and tires from us and never looked back at RFTs.

Neither one is really designed for cold weather or snow. I drive my car very little in the winter...only if I have to and never in snow. Technically, the PSS (And the run-flats) are summer performance tires...but I can tell you the PSS is great in the rain and better than the run-flats.

Sure, you can drive either tire in the snow, I would not recommend it unless you're in a giant parking lot practicing your drifting skills. Plus, some would argue (Though I haven't experienced it) that you will wear a summer tire quicker by driving on it in the cold...

They really are amazing in the wet. One of my track days last year (Lime Rock) was a torrential downpour and the grip was stunning. I kept pushing harder and harder, not sure where I was going to lose traction and by the last seesion I was passing M3s, Audi S5's, etc...of course, there could have been many factors, but I strongly feel a lot of it had to do with the rubber. Good luck and enjoy!

Just quick question here. I do have an M sport suspension, how does it feel with Michelin or Continental? I'm talking about PSS or DW. How if I put 255 on the back? I'm also thinking about going 225 for the front setup. I'm running stock 18" wheels. Is there any rubbing issue? Which setup do you guys recommend? What tires?I use my car plainly for street use and no intention of use it for track.

Thank you,

Carlo

I replaced my run-flats with Michelin PS A/S Plus 225/255 tires on stock 261M rims. No rubbing at all under high speed cornering or with 4 people in the car. Does make the car understeer a little bit more though.

Silly question here, what causes it to have more understeer? You're running your stock M suspension right? How's that feel?

I have the Michelin PSS now and had Continental DW in the past. I have the M sport suspension too. Went to the 225 front, 255 rear with both, on stock wheels. No rubbing with either.

Both ride much smoother with far less of the jarring bumps than the original RFT's. Better traction too than the stiff RFT. Michelin maybe just a little better ride, but really PSS and DW are similar in ride and handling. PSS are supposed to last longer and have a very good (for summer performance tires) tread wear rating.

Okay. One more question because I'm just curious. Does any of you know if pirelli a good choice for our car? I heard pirelli p zero nero is quite good but not sure if it's available for our car. Any information that you guys can share with me regarding pirelli? I know the price might be more expensive but just want to get some more information since I want to change into the right tires. I know for sure PSS is one of the best

Actually, that is not quite true. A wider tire will NOT give you a larger contact patch, only a wider contact patch. The only things that determine the SIZE of the contact patch is the weight on that wheel, and the pressure in the tire.

For example, 340 lbs sitting on a tire inflated to 34 PSI will mean a 10 square inch contact patch. Double the pressure and the patch will be half the size, cut the pressure in half, and the patch will be double the size.

And on that note, can not wait to order a set of nice wide Mich PSS on Apex rims for my car. Wider contact patch means better handling.

Also, on a related note. What do people take with them on long trips when no longer running the RFT's? Any compact spares available?!?!?

That's mentioned in another thread: Some carry a full spare in the trunk, some carry a compressor and a plug kit.
