Michelin PS 4S - Worth It?

[25 IS V8]

They are absolutely worth it. For my 2025 IS 500 (I no longer own an M2 Comp), I went from the stock 235/40 and 265/35 Bridgestone Potenza's to 245/40 and 275/35 Michelin PS4S tires. I also swapped the rubbish stock front LCA bushings for RC F bushings. You cannot imagine how much better this car is now.

Pilot Sport⁴ S
- Dry Grip, 10/10 - as good as it gets for a "Street Tire", these can do Canyon Duty.
- Wet Grip, 8/10 - As good as it gets for a Summer Tire.
- Noise, 5/10 (worse as they wear) - It's a performance tire, they are loud.
- Poise, 7/10 - Good stiff sidewalls, they do tend to tramline a bit however. They start getting sketch under 40 degrees (better as they warm)
- Wear, You're getting a good 10-15k mi out of these - tops

Pilot Sport 4 A/S
- Dry Grip, 8/10 - as good as it gets for an "All Season", these can do Canyon Duty but not as well.
- Wet Grip, 10/10 - As good as it gets.
- Noise, 5/10 (worse as they wear) - It's still a "performance" tire, they are loud.
- Poise, 8/10 - No real change here outside of they are not sketch under 40
- Wear, You're getting a good 15-20k mi out of these - tops

tl;dr
PS4S is the best street tire there is IMO
PS4A/S, You trade in 20% dry grip for 20% more wet grip and you can drive on them under 40 degrees
- I'd rock PS4A/S before I'd trust any other Performance Tire.

And the PSS5 (I wish they'd stick with a naming convention here) somehow improves on all of this.

Hello,
I can't get used to the OEM Bridgestone tires. I tried to adjust pressure several times but nothing is helping.
I read great reviews on the Michelin PS 4S all season but I'm hesitant to make such an expensive purchase especially now that the Bridgestones are still almost new with only 5,000 miles on them.
Do the Michelins really makes a difference? Are they worth it?
Your thoughts please.
Thanks

wdym can't get used to? are you tracking it? I legit see no difference between chinese tires and ECSForces when I'm street driving (other than noise).

Not an apples to apples comparison, but my Bridgestone Potenza S001 tires were utter crap. Are you trying to say there's not much difference between the Bridgestone and Michelin tires? Because there absolutely is.

I have the Michelin all-seasons and they are SO MUCH better than the stock potenza's in every way. I live in a place that gets all 4 seasons and I will drive my Z in below 40° F quite often.
Mine are pretty new still maybe 1k miles on them, people say they have more road noise which makes sense but honestly I cannot tell.

Sorry, but your rears are definitely not new. Mine wore out by 10k

I went with the Pro Sport 4S (the all seasons are Pro Sport AS4) and have been happy with their performance even in the rain. Not enough winter weather down here in Texas to justify an all season. My first set of PS4S rears were "below spec" when I was around 28 or 29k and replaced with a prorated warranty. My next set I may try something that will last a bit longer.

I felt the same, Bridgestone are not enough for the Z. Mediocre grip when warm, slippery when the temps got into the 50s.

I got a full set of stock size PS4s. I trust the car much better now. I’m not getting any wheel slip unless I want it. When I fishtail the car, it grips and goes in the direction I point it. I wish I had done it sooner.

you’ll also be able to get some money for the Bridgestones on marketplace.

When I had my Bridgestone tires, they were so damn loud. You could hear them all the time. I'm not sure why manufacturers continue to use them as OEM. But them again, it is probably less expensive for them to do it.

Look at the continentals.
tirerack.com does reviews on all our tires.

Go with the Michelins , I had them on my C8 z51 pkg. which came with PS4s but switched to a set of AS during winter months. The Z has too much torque for the Bridgestones. I’m currently running the PS4s now on my Z Nismo.

I drive my car year round so PS4s in the summer cause I track too and then winters for winter.

I had PS AS4s on my last car and they worked great until they started melting on track, but you are not driving that hard on the street and you shouldn't be driving that hard on the street.

AS4 gripped great on the street though. Was at 500 rear wheel on my last car and it had no issues with a 285.
