Hey guys,

I currently have Pirelli on my new M5 and they suck in the rain (as I am in Seattle and weather is starting to suck now). I called a few places and inquired about All Season and they don't make them for the size I'm currently running (F265/35/R20 R295/30/R20). The biggest size they have for Michelin Pilot Sport A/S 3+ is Front:255/35/R20 Rear:285/30/R20. The car currently has style 343 wheels which is Front +9 Rears +10. I'm curious if going down -10 in width will give it a sketched look. Does anyone have this setup already?

Added pics of what I currently have

Thank you,

lol.. I was just researching for the last hour on tires for our climate. Its not an easy find is it? The best tire for our climate hands down are the Michelin Pilot Sport AS 3+ like you have mentioned. I've had them on 2 separate cars, phenomenal tires. Super dissapointed they wont work., I would not want to downsize.. can barely put the power down w/ the 295s.

Right now.. I'm eyeing the Toyo T1R.. at least that's what my rep is trying to place me into. 275 Front/ 305 Rear

Also found these all seasons.. but they look a bit rough tread wise for the dry in terms of putting power down: Bridgestone Potenza RE980AS @ discount tire.

You ever find anything suitable?

I've also been doing extensive research on this and what I currently believe is our best bet is Pilot Sport A/S 3+ with 275/35R20 up front and 285/30R20 in back.

Those Michelins run relatively wide so you're not giving up *that* much width in back, but yes its not ideal.

Attached is what I'm looking at. Red are OEM summer sizes and green are what I think are best bets.

255/35 on a 9 and 285/30 on a 10 aren't even stretched at all.

265/35 and 295/30 are maximums for the 9 and 10, so one size smaller would still look meaty.

Yea, should be fine.

The Michelin's are clearly the best all-season tire. However, the Bridgestone is the only one that comes in nominally the "right" size for our cars. Its not as good, but FWIW at least it is the best tire for wet weather.

In the dry I wonder if performance would be better with 255 and 285 Michelins or 265 and 295 Bridgestones.

Here in NYC with a lot of parallel parking and potholes, rim protection is a not-insignificant consideration as well...

Personally I think I'm going for the Bridgestones. They're the clear leader in the wet, 1 out of 3 days in NY is wet, and accidents per mile increase 4x in the wet. Realistically I'm rarely going to reach my dry grip limits but wet grip limits are much more likely to accidentally come up against wet limits.

And they come in the "right" size.

Getting ready to finally buy some tires. While the RE980AS are definitely the no-brainer choice, the glorious Michelin Pilot Sport 4S (a 3-season tire) are available in our sizes and outperform all of our all-season options in the wet.

Any thoughts on if the Pilot Sport 4S are at least workable at cautious speeds on a couple of days of snow+ice per year?

Went ahead and got the Michelin pilot sport 4s for the rears. Might get them for the fronts too.
