All Season Tire Comparison - Real World
For those who may consider dumping their OEM RFTs for all season tires I thought I would try and summarize my recent experience with 3 different tires over the past several years. While only one set was used on a Z4 you may find my impressions useful.
1. Yokohama ADVAN S4 - installed these on an 07 335i vert and on an 09 335i vert. Handling was equal to the RFTs. Ride was improved, perhaps about 50% less jarring over bumps, road noise slightly better than the RFTs. On a scale of 1 - 10 I give them the following scores: Handling - 9 Noise - 8 Ride - 7 Can't comment on treadware as I only put about 8K miles on them. http://www.tirerack.com/tires/tires....odel=ADVAN+S.4. 2. Yokohama ENVigor (W speed rating) - these are the high speed version of this tire as it is also sold in lower speed ratings. Survey results are in the HP AS section of tire rack but this is for the lower speed rated tire. I suspect the higher speed rated version would have similar results. It is the top rated HP AS tire on Tirerack. I have these on my Z4. Ride imrovement is significant over the RFTs, no noticeable decline in handling, road noise is also lower. Wet performance is excellent. Have not driven in any snow but in low temps I detected non decrease in handling. Handling - 9 Noise - 9 Ride - 8 I have 4K miles on these tires with no noticeable wear. http://www.tirerack.com/tires/survey....jsp?type=HPAS http://www.tirerack.com/tires/tires....or+%28H%26V%29 3. Continental ExtremeContact DWS - Just installed a set on my 08 VW R32. Marked improvement over the OEM Dunlop all seasons. Ride is better, handling is good but not as crisp as either of the Yokohamas (the ADVANs have the best handling feel). Noise is very low, they are quieter than the Yokos. Have not driven in rain or snow but they are rated very high by TireRack in the snow. Handling - 8 Noise - 9 Ride - 9 Treadware - can't comment as I have only had them for a week. http://www.tirerack.com/tires/tires....emeContact+DWS Summary, I find the Contis to be closer to a touring tire than a true high performance tire. That said, if you are an average driver and won't be using your Z4 on the track or drive it hard, the Contis would be a good choice. If you want to maximize handling, I would go with one of the Yokos, with the ADVAN being slightly better for handling but the ride is a little rougher. At one time the ADVAN were top rated by TireRack in the UHP AS category, but the Contis have surpassed them in the last year. I can see why because they do maximize ride and treadwear both of which appeal to the average driver. http://www.tirerack.com/tires/survey...jsp?type=UHPAS I have no regrets switching to a non-RFT all season tire. If I have a flat I will call BMW or AAA. Used to carry a slime kit and a jack but decided I probably wouldn't use it so they are both in my garage.

Once these run flats are worn out I'm going to replace them w/ non RFTs but I'm wondering what happens if you get a flat.
I guess the only option is to get it flat bedded to a tire shop. |

Does BMW NA provide a one year road assistance? In Hong Kong, we are provided with a one year road assistance, renewable for another 2 years... (But than HKG is a small town in size to NA...) I was told that BMW was trying to substitute the RFTs choice by providing the road assistance (??!!))

A lot of main roads in Holland have dual-layer porous asphalt. It reduces the noise a lot and having RFT's is not causing a lot of tire noise.

I totally agree on Continental DWS.
I wonder why wouldnt they make 285/25/20 size. DWS is very solid on wet weather and black snow especially in Seattle or Vancouver in my experience.
