Michelin Pilot Sport 4S

[OF Hero]

Just curious if anyone has tried these tires yet on those transition days in Fall & Spring where it might be like 35 deg and DRY in the morning before it warms up to over 50 during the day. I've taken the MPSS out in those conditions a few times (absolutely no rain or snow) and if driven carefully, never had an issue. I know some "tire purists" will say to never take it out below 40 deg, but sometimes it's just not practical especially on those days where it's only cold for a few hours in the morning.

I had my PS4S tires installed in the fall last year prior to the rainy SoCal "winter". Definitely more traction in the wet. But we never see snow or temps below the 40s unless it's in the mountains.

Just this past weekend though, the San Diego Chapter of the BMW CCA went on a Holiday Tour on the windy, twisty back roads in East San Diego County. The route took us over Mt. Laguna, 5738' elevation. There was still some snow on the side of the road in the shady forest parts from a previous rainstorm and the temp showed 36*. There was some runoff and apparently that runoff across the road was icy/slushy. I was in MDM mode and the car lost traction 3 times just running through this short section with no throttle. I put DTC on again and switched to D2 until the temps got back over 40*. The tires felt like bricks below 50* and I definitely didn't push them again until the temps were over 55*.

LOL! If it is cold and rainy, don't drive like an idiot and you will be fine with these tires in socal "winter". Definitely don't use MDM. These tires are not magic.

I have driven OEM tires and these through out Seattle's rainy winters the last 15 years in M cars and never had any problem, down to below freezing on dry pavement and above freezing on wet pavement. Sure the rubber gets hard, but it still has plenty of traction, definitely better than many other cars on the road. Just drive safely.

Just to confirm, the people running 265/35R19 and 285/35R19 PS4S tires have the generic versions for both sizes right? As far as I know generic is all that's available for the PS4S but want to confirm; not very well versed in tires etc.

My car is a stock F82 with OEM 437M wheels.

I just got this setup on my car. The ride is much smoother. Will need a track day to test performance.

Will original Michelin PSS perform better in such conditions?

I drove mine several times in low-30s on dry pavement before switching over to snow tires/wheels a couple of weeks ago. Not one issue.

Anybody running MPS4S 265/35/19 on front 9.5” rims and 305/30/19 on rear 11” rims and experiencing issues with traction control? Is it just on the street, track or both? It looks like the 275/285/295 are all around 10” tread width and might look too stretched on the 11” rims and the 265 front will be a little meaty. Trying to get my tire setup for Apex SM-10 rims.

Yes, I’m running ps4s 265/305 on 19” 9.5/11 wheels. No traction control issues.

Good to know, thanks, I’m figured that running same diameter would be ok, since the Winter package from BMW has a square setup and same diameter tires.

On that repack there are 2 diff 285 35 19 4s. Which one are people getting?

[marvinp]

Here's a brochure I got from Michelin reps during M Track Days and it includes part #s for PS4S. I plan on getting what's recommended on there. Hope this helps anyone.

They are simply recommending stock tire sizes for stock wheels, which is how it needs to be. Not everyone installs them on stock wheels though, so the recommendations become meaningless in such a case.

The XL version from Tire Rack is what I went with and they are excellent.

[rosenbergendo]

Both say XL.

Wheel: 437M
Current tires: Stock Front PSS 255/35/19; Stock Rear PSS 275/35/19

I need to replace my rear tires, but not sure whether to get 4S 275 or go to 4S 285?

I don't want to replace my front tires yet, as the tread is fine. In this thread, it seems 265/285 is the preferred set-up, but is it fine to go 255/285 until I need to replace the fronts?

Yes absolutely fine, I am currently running a 255/285 setup.

Can anyone confirm if stock 19s lowered on Swift springs will have any rubbing with 265/285/35/19 setup?

[aliiin]

Do these ever go on sale? Read on another thread a retailer on eBay gives you $100 off $400+, couldn't find this deal though (although he said the sale happens in March sometime, so not sure how long I should wait?).

I'm buying a pair of 285/30/20's soon for my 666M. Wondering where people are getting the best prices for these?

Sill question, I put mine in last night when I swapped off my snow tires....is the 4s not directional? There was no arrow pointing to which way they should rotate...

4S is non-directional but there is an Outside/Inside.

[LAKERS333]

Just switched from the 295 35 19 to the 285 35 MP4S 19 rear tires, I have to say that although the 295 has less tread width compared to the 285, look wise the 295 looks much better and more aggressive than the 285.

In the future I might revert back to the 295 if the traction/grip is not noticeable difference. Have not drove the car enough as I cant imagine it being much different grip wise.
