I looked at tirerack and others, and no sign of a 285/35.... you sure you didn't mean the 275/35 or 275/40?

If truly a 285/35, any links to the specs? if verified, then that makes my decision easy: stick with the star spec BMW 295/35R19

When I made my thread back in Sep-2015, the 285/35R19 generic PSS was listed on tire rack with a 10" tread width (see the table at the end of the OP in that thread). I even commented on the fact that it had strangely a narrower tread than the generic 275/35R19.

The generic 285/35R19 is still listed on TireRack, albeit, for some reason, without the tread width anymore.

wow, I must be going blind! LOL

I looked again after your post, and didn't see the 285/35 generic. Oh well, I just had a conversation with Michelin, and they said they don't have those numbers, but they mentioned that size wise the P4S will be almost identical to the PSS in their sizes (similar molds, etc), so I'm guessing if the 285/35 was that small, likely the P4S will be the same.


which, again, makes my decision MUCH easier: 295/35 star spec MPSS

Thats an interesting conclusion from that information. Why are you choosing MPSS over MPS4S if you're buying new tires?

The information on the 285/35/19 must have been wrong on TireRack cause that doesn't make sense. Tiresize.com says the 285/35/19 is 11.4 wide and the 295/35/19 is 11.9.

The Star Versions in those sizes have a smaller bead width that work with the smaller 437m/666m bead widths (among other differences) as CanAutM3 referred to.

Don't feel bad. I checked the price of the MPSS 295/35/19 Star Version yesterday and could have sworn they were not listed at all. No info. Period.

Luckily I took a screenshot that proved to me I was badly mistaken in that instance.

Those 295/35/19 on Florida West Coast still available in Classifieds.....

Don't confuse section width and tread width...

Oddly enough, the standard nomenclature for tires is not very reliable since the section width (the first number in the tire designation) varies a fair bit depending on the wheel width the tire is mounted on and has no direct correlation with how much rubber is on the road. On the other hand, the tread width varies very little with wheel width, is much more representative of a tire's grip ability and yet is not part of the standard nomenclature. Go figure...

I would consider the Contis if I had a way to buy them for a good price. They do seem to have good reviews.

Not independent testing but an opinion compared to the Conti 6.

Wouldn't you want MPSS unless you are replacing all four tires? I'm not sure if MPSS and MPS4S have exactly the same tread pattern but assuming not, I thought mixing tires might cause with how the car drives.

Quick question... TireRack lists the section width and tread width of 295/30/20 Star Spec MPSS as 11.9" and 11.6" while the numbers for generic MPSS are 11.9" and 11.2". Can it be really possible that the star spec 295s have that little difference between section and tread width?

Yes

That means it is a tire that sits really "square". Note that in TireRack, I read 11.5" and 11.6" tread width for the generic and star spec 295/30R20. So both a very close in terms of tread width. The Mercedes M0 is much narrower at 9.4".

Thank you! I didn't know tread witdh basically describes how the tire sits. I thought tread width was section width minus the width of the grooves on the tire.

There is no "official" way to measure tread width per se and it is not a stat that is available through the official and standard tire size nomenclature. However, tread width is a really important one since it much better depicts "rubber on road" compared with section width, which in itself is rather meaningless.

TireRack have devised their own methodology to represent tread width that I find very informative. See here: http://www.tirerack.com/tires/tirete...jsp?techid=201

I thought you were replacing all 4 my bad.

If I were only replacing 2 I would go MPSS as well but I need 4 new tires for my new wheels.

Thanks for the link.

Interesting they noted how inconsistent the wet area was depending on the timing before they state the MPS4S were only slightly better. Hard to make comparisons like that if the playing field isn't equal.

Who knows. Maybe the MPS4S will be slightly better.

However, one can only ask again. If the MPS4S were actually marginally better in with their wet grip, why did Michelin not release those actual test numbers in all their press releases and publicity, especially as wet grip and dry grip were areas where the Respected Independent Reviews note the SC6 beat the MPSS?

Instead the posted lesser important stats and tried to make the margin great with deceptive non-linear graphs (conspicuous by their deception).

Again, the wet and dry grip numbers are conspicuously absent, which only leads to questions.

I'm not the one who is replacing tires. You were replying to someone else but I just wanted to ask for clarification purposes

[gds52]

Anyone in Europe got these tires yet?

[sydenfareren]

I have them. But sadly it is still winter in Norway, so i cant test them..

Looks good. What size are those rims?

[CPT Smuggs]

Great video review of MPSS vs MP4S after 1,000 miles of use.
tl;dr; MP4S is the new top tire.

There you have it. Everything Michelin said comparing the 4S and PSS was just verified by this video. My 4S's are set to ship the first week of March. 265/30/20 and 295/30/20 are the sizes I'm running on a 20X9.5 and 20X11.

Same here. Cant wait to get them on! Hopefully by Friday.
