Run flats or regular tires ?

Many poor Mexican soles are old tires.

Do not let them burn.

Sometimes....

Conti Comfort Kit, not.

Is it a good option to go for regualr tires and buy and repair kit or go for run flats.

Newest gen RFT's still not as good as, say, Michelin PSS, several dimensions.

Not a disappointment like 2008 OEM RFT's either. However, below 60°F and especially <50°F, summer tire ride quality suffers. Depending on where you are in North Caroline, can be major.

Sure, sure....plenty warm now. But what about January?

FYI - I run Michelin PS2's, grossly better than the OEM Potenzas on my paws when I bought the car. Guessing M division thought they were better too.

Been running summer tires (Conti DW currenly on both BMW's) for as long as I have lived here with no issues other then snow. 1" will kill them & its time to take a 4X4 with M+S

But I thought The DSW's are all season tires, wouldnt they perform well in winter.

DWS all season DW summer both good in Raleigh

Yup - don't expect top handling - do expect excellent service, you locale.

Oh, I forgot...NO mileage penalty for a staggered fitment (as with the Michelin RF).

Not sure how the pricing works out vs. Conti if you figure in the ContiComfort kit pricing.

Attn, OP: DON'T count on a "goo" kit to get you out of trouble if you mount non-run-flat tires and you get a flat. They are only good for simple nail punctures in the IMMEDIATE tread area...and YES they will clog your TPMS, requiring a replacement (about $55 through Tire Rack).

I have those tires. If there is a real improvement in ride, it is subtle.

What do these stand for can i see somewhere all the abbreviations. ZPP/6FL/PCD/CA/6NL

Low profile tires and NYC are not a good match.

Hi CA,
There is $100 rebate at discount tire and i am planing to get then tomorrow.
how is the performance until now on your DWS tires.

So far very impressed. Good tight handling, quiet and excellent ride quality. I like them better than the Pirelli P_Zero Neros that they replaced and they are an order of magnitude better than the OEM Bridgestone RFTs that the Pirellis replaced.

The combination of the Conti tires and the Koni FSD shocks have transformed the car.

OK, I will get them installed at discount tire, the sales person was insisting on the Michelin MXV4, but i am going with the conti's.

Thanks very much for your replies.

If they are run flat soles, do they have to carry the conti comfort kit?

I think you will be very happy with your choice. We are on a weekend excursion to Connecticut and the tires are great on the New England twisties.

Totally agree. I love my Conti DWS on my Z4 and my wife's 530xi. Great tires!

I also bought the BMW Mobility kit (20% off) for the Z4.

The 530 has a spare.

While the MXV4 is a touring all season tire, the DWS is a high performance A/S - and costs much less as well.

I'd find a different sales person.

I'm assuming that is the RE960AS version you are referring to. So you do not find the ride quality to be that much more comfortable/soft? What are you coming from? If I remember correctly, you have a non-sport e91, so you have the 17".

I have the 17" tires, and originally had the conti pro contact SSRs, which I had no issues with, but then got new wheels from someone that had the bridgestone turanzas. There didn't seem to be a big difference, but now that they are getting up there in mileage the tire noise is getting unacceptable (still plenty of tread left).

So basically, i'm looking to either get the conti's again, or these new RE960AS (price isnt' that different). Do you have any other thoughts/input on your new tires? All the reviews seem to indicate these things are wonderful, so i'm curious about your real world assessment.

(tried to send a PM, but your mailbox was full)

I opted for the Conti DWS due to cost and being laid off at the time. Definately a performance difference as they tend to "sway" in corners, it feels like your drifting slightly. The Conti are much quieter and half the cost, all season and high perormance. I do miss the RFT, as they could bite the asphalt more agressively.

Possibly, I have had trouble with mine getting an error message "TPMS inoperative" & beeping all over the place. Used my JB4 programing to shut it off.

I have 16" RE960AS. Like them very much compare to 17" ***1054;***1045;***1052;. The ride and handling are so much better. Those OEM bricks used to jump over bumps, when taking a ramp, the car was shifted sideways, not very pleasant. But remember-my suspension is not great, it is X-drive.
I understand that the size is not the same, but the difference is big.
Had also 18" go flats DWS and was very happy with them, but could't stand the spare donut in my luggage compartment.

I just replaced my continental run flats on my 2008 328i with 52000 miles. The Yokohama 580 's nonrun flats give me the ride and handling I expected for daily driving. If I were to race or travel in remote places with NO AAA then the run flats have merit. Otherwise they are too rough and loud . Stearing is a bit squishy if you are a very fast driver in the curves. most of us never notice the differnece. THe BMW suspesion is a great touring match with regular tires given my experience . Buy a can of the Green of green slime

I have 17 225/45 at every corner. It came with the stock Turanzas, which were meh. Ride and noise were not issues, but they did not wear well and handling was poor, particularly at the end of the tire lifespan.

Switched to summer only Kuhmos. The summer performance tires were a major improvement in handling, slightly noisier, and rode about the same. They wore poorly, and they were replaced after just about two years.

Switched to the new 3G potenzas. Overall, they are fine. They are noticeably less sticky than the summer tires though and the ride comfort is only a modest improvement. Nice tires, but not the paradigm shift that is advertised.

It is interesting. I was wondering how are they in 17" and 18" sizes, because with 16" I feel a huge improvement.

Good to know as the 2nd generation Bridgestone EL42s on my E91 are 16". They do OK although the wet traction is nothing to write home about. When pumped up to 35/42 lbs., the handling is surprisingly good, but the ride suffers (surprise, surprise!).

Looks like I'll replace them with the 960 AS RFTs when the time comes.

Just remember: I feel improvement compare to 17" OEMs, so it is not a clean experiment. But my 16" are quiet. The ride and handling- I can't wish better with that so-so suspension.
