A few buddies are running the PS4's and really like them. Say wet grip really good. I tried to find them for my GT4, but Discount Tire couldn't locate any, sold out. Had to go with the more expensive Dunlops - dang it.

Best honest review I've seen on the 4S vs. MPSS... generally it confirms some of the comments, better wet grip, better ride and fuel consumption, AT THE COST of losing some ultimate dry performance!

So, price being equal, I'd say pick MPSS if you live in mostly drier places, but PS 4S in mixed environments.

I heard it differently... He actually says that the M Sport 4S' dry grip is slightly improved... he goes on saying that at 8/10s and beyond there's perhaps less feedback (perhaps because the tire is more supple) and this only noticed if compared against the MPSS back to back... Better in all areas, dry, wet, NVH, wear.

All in all it looks like the Sport 4S is a better street tire. For track I would get the Sport Cup 2.

But you do need that extra at 8/10th, not street driving. Again, if I lived in CA, MPSS probably the better tires if you also track, but here in Vancouver with our wet weather, I'd pick Sport 4S next time. Albeit, my MPSS have done amazing in the rain (vs PS2) and if cheaper I might pick another set.

PS. Right now, MPSS costs $230 less for a set...

4S is an amazing tire. Does anyone know if they will produce a (N) rated version ? My dealer insists that for the warranty.

alexb76

Are you serious? I've never heard of that... like your engine will blow up if you have the wrong tires on?!

I just checked and neither MPSS or PS4S are made N-rated in "our sizes"... they make 20inch ones (for the 991) with N-rated.

Clubber

Not for the engine but mostly for the suspension parts...

Where can I buy either set locally?

In the scenario of a fair-weather only car, would Pilot Sport Cup 2's be the way to go? This is not my daily.

I'm undecided between 4S and Cup2's. I think wear is the only concern outside of getting caught in an unexpected rain storm. In that event, I will just slow down.

Thoughts?

If you don't track, skip Cup 2, too soft and not compliant on the street and will wear out so quickly costs will double. If you're mostly driving dry and don't need better wet traction of 4S, best deal right now is MPSS which is $250ish cheaper.

Most tire shops can get you Michelins, shop around for best price. I usually pick a few close spots, call em for prices and find one that works best. We also have an online store http://www.1010tires.com/ which is Canadian, but then you need to figure out installations.

TireRack prices (4 tires F & R):

MPSS - US$1120.80

MPS4S - US$1157.88

Price diff: US$37.08...

Interesting... Maybe prices went down for 4S over night, I compared Tirerack prices last night, it was $230.

I have about 5k miles on a set of PS 4S on my DD right now. Great tire. Noticeably quieter than the brand I had before. Does well in both wet and dry settings. Several techs at 2 different shops in 3 different locations have commented on what a good choice I made. Not N rated but that is forthcoming as I am told. I will be replacing these with more of the same for what it's worth. The car's designed speed rating requires the compound to be somewhat softer than I would want for a DD but it is still holding up well enough.

That' great news. Do you have a time frame ?
