265/285 width tires on stock PP wheels?

[AZ_Ryan]

Man you sure are making this your hill to die on, and you've thoroughly hijacked the thread. I suggest to you start a new thread under tires and wheels.

As for the temperature question, If you do a Google search there is a ton of information at your disposal including videos. It is widely known that summer tires get hard and lose grip in cold conditions. GM even did a tire recall a few years back because they discovered micro cracking in their summer tires due to low temperatures. Again lots of info is out there if you just do some research.

This is what tire rack says on the subject-

This thread seems to have gotten off topic. I’m looking to increase grip during summer drives over stock (p zero) tires. Not interested in dropping down to all seasons. The 4S tire would be the logical next step to improve grip on stock tire sizes since moving up a size may not improve anything. I don’t plan to drive the car below 20 F it will stay in a heated garage. In temps between 25 and 50 F I simply drive conservatively. It will not see snow.

Sorry for the thread derailment. Not sure how that got off track to quickly.

Yes, I would highly recommend the Michelin PS4 summer tire or the Continental Extreme Sport Contact 2s. I have used both and they are excellent tires that ride and grip great in warm conditions. FYI Michelin now has a PS5 that is replacing the 4. I dont know how it compares to the 4.

the poblem you will have is pretty much every summer only compound is not recomended to drive on below 7C (45f) , not just because of traction but the hard rubber and the cracking..the cracking doesnt care if you drive conservatively, flexing soft compound when they in freezing temps will shorten the life end of story.

the stock p zero and ps4s arent going to be measurably different in summer conditions on the same size tire, youd only be able to measure the differences on a track, on the street youd never notice. If you went down to a 100/220 treadwear tire youll get more grip than a 300 treadwear but they also dont last very long.

I went up to a 275/305 in the PS4 AS to get the wider tire to help offset some of that traction loss from the summer only in a 255/275 , I am sure if I went to a track I could tell but the PS4 AS seem to have the same if not more grip than the p zero with the wider width, and when it was getting cold and rainy here they were still excellent, going the AS route just let me run the car in Novemebr and late march/april, so give me another 2 months a year to drive. Not sandblasting my car with gravel from sticky tires is a nice perk, and theyl last twice as long...and they look good lol

I can tell you the pzero OEM were awful in october when we had a couple days just above freezing. The PS4S on my CT5V AWD were also abysmal in the cold

Anyways, if you want measurably more summer grip, go wider in a summer only. or drop down to a 100/200 UTQG tire. Could also look at the Indy 500 tires, they are half the price of the Micehlin and Pirelli and if you drive them in the cold and need replaced early, it wont hurt the wallet so much. But they dont have nearly as much rim protection as the Micehelin and Pirelli

for keeping stock size, yes 4S could be an improvement. Winter depends entirely on what you experience in your local area. since everyone seems too lazy to just see what Michelin themselves say here you go.

also just note, a lot of the stuff seen on here is personal experience. will PS4s handle better than P-zeros? sure probably. Ask anyone here if the NT555G2 is a good tire and some will act like you just committed a crime for even mentioning them, but my NT555G2s are handling all 815HP the engine makes with no issues.

Probably need to wait another year or so for wider availability. There are not that many sizes available today.

Anyone try to fit 265/285 width tires on stock GT performance pack wheels? (Comes with 255F/275R width) if so, what did it look like and how did the car handle?

When it’s time to replace tires thinking of moving from the Pirelli P Zero 255/275 to Michelin Pilot Sport 4S 265/285. Wanted to see if anyone tried it and if it does crazy stuff to the stability control system.

The tires are stretched pretty wide on the stock rims for best handling. Going up 10mm in width will work just fine for all types of normal driving. I did the same thing on my 2018 Escape Titanium and I'm very happy with the result. It rides a bit smoother and I don't notice any change in handling. The looks are improved as well, in my opinion at least, as the wheel wells are filled out a bit better and that "rice rocket street racer stretched tire on too wide a rim" look is much less apparent. I'll probably do the same thing on my 2025 Mustang GT PP when the time comes for new tires.

Keep in mind the P Zero PZ5 is supposed to be a big advance on the PZ4's that come on our cars.
Tyre Reviews put it up with the PS4S in most areas.

Thats saying something. PZ4s are already quite a bit better than than the older versions.

I can't say I've any complaints. I've had PZ4's on two cars now.
I did think Mich PS5's were better in some areas. They have lot of grip considering their low rolling resistance. I don't know how Michelin achieve some of their results. I think it involves a cauldron and an old hag.

Tire Rack comments say they do well at 40° Fahrenheit (7 Celsius) and that they are an improvement over the PS4S. They are 340 tread wear, so probably will last a little longer. Tire Rack shows them available only in 17 and 18 inch sizes, though. Michelin's web site shows 19, 20, and 21" sizes, but nothing wide enough to fit my Dark Horse handling package wheels (and all of the sizes say "Check Availability," so I am assuming availability is very limited).

Are you referring to PS5 or PS5S?

LOL, I did not even know there was an S 5, so the PS 5 had that comment in the comments section at Tire Rack. Now I see a Pilot Sport S5, but at least on Tire Rack there are no 19 inch tires.

That's interesting. I had PS5's on my last car and liked them a lot, steering feel was better than the P Zero PZ4's that were on before. But quite few reviews rated them lower than than PS4S for "enthusiastic" driving. I've also seen vids of cars running them at the 'Ring succesfully, as long as track temps aren't too high.
I'll be pricing them among others when tyre time comes up for the Mustang.
