Guys after installing the new tires, will I notice any differences in the driving expirience? Like will the car feel like it picks up faster because of the increased grip?

I ask this because many people seriously advocate adding new tires as the first and one of the most important mods for this car.

I think the "switch tires to fix the car" is bunk unless you are going with 245+ and tracking the car. On the street, the car is near perfect, if just a bit too rough. I'm guessing any change you notice will be psychological.

I switched to MPSS because they were about $100 less than OEM, and seemed to have the lowest number of complaints about about quality or sidewall flex. Also, the Primacy tires lasted me just shy of 20K miles, and people said the MPSS should easily last 30K.

I have 215 on my car. I have never tracked the car.

The main difference I notice is that they are softer.

Con: The car feels less darty - less on rails. The steering feels more artificial, very electric.
Pro: Going around long sweeping turns at higher speeds feels more controlled. Minor corrections no longer send the car across the road.

I haven't noticed any increase in grip. As I mention, the car feels softer and allows you to make minor steering corrections and be precise with placing the car. You can spin the rear tires with 3K revs just like the Primacy tires. I haven't understeered, but I never found that to be much of an issue with the Primacy tires. Again, just be smooth.

The MPSS feel solid in the rain. I recall the Primacy tires struggling around corners and braking at low speeds.

I think the MPSS take awhile to get warmed up. When the tires are cold, or the road is cold, they seem to struggle a bit. Recently we have had a few 60 degree mornings and 95 degree afternoons. There is a stark difference in grip at those two temps. In lower temps, giving it just a few revs and pulling out into traffic will lead to a bunch of wheel spin and more squealing than you might expect.

I'm curious to see what happens in the winter when it is 32 out.

Hmm my Z2SS were nearly gone by 20k miles, well past the wear bars, but 3x track days and ~7-8 autox events in that time.

Road surface and tire pressure have a role to play as well.

I've got about 7k miles on the MPSS right now and they look like they'll easily hit the 30k mile mark as long as I don't hit the track and keep the autox time low.

Tires wear differently, whether it's due to differences tire to tire, driving styles, conditions, etc. Experiences rarely translate 1:1, but there are some generalities. I think it's fair to say if you are blowing out MPSS in <20k miles you'll get like half the mileage out of say a 200TW tire like Z2SS or RS3/4.

For every bunch of reviews saying they get 30k+ miles on MPSS there's some guy in a Corvette or Ferrari wearing through them in 5k-15k miles.

I can't see how I got 8-12k out of them and people are claiming 30k. I drove 99% straight roads with just about stock power, mild alignment, watched tire PSI and never do racing events.
There are so many people online claiming the same about getting well under the 15k too. Michelins are supposed to have great quality so how could they have such different lifespans?
I can see if I was racing around sideways but 90% of the car's use is going grocery shopping. I'd like to see how somebody drives and gets 30k+ out of them. It must be painfully slow.

Now I'm curious how you drive. 35 psi?

Is it mostly freeway miles at the speed limit? Higher speeds will wear the tire out quicker due to more heat. My commute isn't fast so the 'painfully slow' part may actually be true (although it's not my intention to drive slow) as plodding along in traffic at <40 mph is definitely going to be less wear than >65 mph over the same distance.

I'll have to take a look at mine tomorrow, ~8k miles and 2x autocross events after almost a year of driving, plenty of tread left.

Where I live everything is very close by so I never really get the tires heated up much.
90% of that was 5 to 10 minute drives at around 55 mph or less. Here and there at 60-70 mph, maybe a couple hundred miles of the total.
No real long distance to speak of. Exactly two trips about 100 miles each at 75-85 mph. I don't use the car for vacation travel.
Just a bunch of short normal driving and that's why I don't understand how I went through them in less than half their life expectancy.

Looking at mine this morning 30k may be optimistic and I'll probably be at the wear bars before 20k but I'll probably stretch them to 20k anyway. I'm at about 10k miles now (was wrong looking back at my records unless I'm triple stupid today) and they appear to be about halfway gone if I measure to the wear bar, 1/3 if you are willing to run them until they're slicks.

Maybe that's the trick, people being cheap and pushing them past the wear bars?

Ended up going with the mpss 225/45r17, got them for a great deal.. Hope ill like them!

Guys I had question about when installing the the tires at a shop do you have to buy a new tpms for each tire? Or do they just transfer the current one to the new tires?

the TMPS are on the rim... you are g2g

Haha hope i didn't fuck myself over for winter

How slippery are the PSS tires in the snow, even if I drive like a granny?
....Here in Maryland the weather is unpredictable, one year it snows a lot, others hardly an inch, but the winter only lasts 1-2 months.

I know summer tires are terrible during winter, but i'm wondering how bad. I don't want to switch tires either. Also I don't commute very long.

Will the salt/snow affect the tires grippy compound and cause pre mature wear and cause it to lose the grippy feel?

The tires will be destroyed. You can't even store the MPSS below a certain temp, let alone use them for driving. The compound can't repeatedly freeze and warm up, that would just ruin them in one season. I wouldn't even dream of using them in the winter, but I am in canada after all lol. Even winter tires aren't enough sometimes.

lol bet you mostly use your winter tires in that crazy weather

I was literally just saying the same thing on another thread. lol I can definitely vouch for this. Do not use or store MPSS when it's near or below freezing!

There are some max performance summer only tires that can function adequately in DRY conditions down to about 40F. Michelins are not generally on that list.

Much below that, with any summer tire, you might as well have shopping cart wheels on there. And trust me, you don't even want to think about even 1/8" of snow.

Isn't that a legal requirement in some provinces?
