Are the PS4S recommended for Daily Driving ?

kingjah23

Unfortunately when I bought my new Z the tires were worn out so the time to replaced them is now. I see everyone on the forum is talking about the Michelin Pilot Sport 4 S Tires but as someone who doesn't do any track racing are they worth the investment or are there other tires that would be better value for the daily driver?

I DD mine.

I recently got a set(245/40R19-F, 275/35R19-R) on my 370Z sport coupe as replacements for the OEM Bridgestone Potenza S007 tires. The recommended inflation pressure is 32 psi square. I DD my car and don't track it, although I occasionally do some spirited canyon carving and slicing and dicing on the coastal mountain roads here in northern Cal when the weather permits. I was wondering if you had experimented with tire pressures and had found something good? When I set the pressures to 32 psi on the Michelins the car felt like it was a bowl of Jello around corners. I bumped up the cold pressure to 36 psi square and the car is handling much better. I did put some very stiff Hotchkis sway bars on the car a few months ago, which greatly improved the handling.

I'm at 36 all the way around.

That sounds 100% correct. The Bridgestones are known to have super stiff sidewalls, especially when you go up the performance ladder. So you really don't need much air in them to get stable handling. When I ran RE-11s and RE-71Rs for daily driving, I would have them set at 32 psi, mainly because I found they wear evenly at that pressure. The door pressures were causing more wear in the middle of the tread. I did run different wheels compared to stock, so that likely also affected it. Now I don't daily the car and it usually sits on the Conti Extreme Contact Sports with around 34 PSI.



Regarding the performance metrics listed earlier in the thread are for extreme driving conditions. So during track conditions, I wouldn't doubt the Michelin's worth. If anyone is DDing, they shouldn't be getting near those limits on the street anyway as that's ridiculously irresponsible. So getting a comparable tire for significantly less money would make sense. tl;dr, I would get Michelins if I was sensible about doing Daily driving and track work with one set of wheels.

Thanks for the feedback, particularly on the info regarding the stiffness of the sidewalls of the Bridgestones. That was my impression about the stiffness of the sidewalls of the Potenza S007s, which I liked.

Why wouldn't they be?

These are street tires. It's not until you get into the "extreme performance " aka autocross tires, that you start to sacrifice streetability. These are about the best tires you can get for the street.

Now, there are tires that are more economical and perform nearly as well if you don't need the absolute best tire. Look at Bridgestone and Continental for high quality alternatives.

Well like the op I'm gonna need tires soon, 50/50 hwy and twistys, I'm not hard on the car in the corners and a tire that lasts awhile would be good!

Go read the reviews on tire rack.com for the PS4S. Very positive, if not phenomenal.

abm89

They're good from what i've read. You can't go wrong with them, but I personally wouldn't spend that much money on them. I'm running the Conti DW with no issues.

DW's were replaced by the Extreme Contact Sports. The ECS's improved and competitive in every objective measurement.

The PS4S is a great tire. If that's what you're wanting, its great.

I'm rocking em. I dont track my car but with how easily the back wheels break free I absolutely adore them. Then the few times I go into the canyons or mountains they prove to be reliable and predictable through every single turn. I started a thread on them here, check it out. Lots of people have put in their opinion. None bad.
