Sure your gauge is trustworthy?Guys, so what's the consensus on pressures? I ran my stock PZero AR at 26/29 cold and it wore faster in the middle tread so I think that was over inflated. I've got Goodyear Eagle F1 SuperSport in 205/235 which are slightly wider than the stock PZeros (as has been talked about when switching to Michelins previously, so I think the Goodyear size = Michelin size). I've dropped by 2psi front and rear to 24/27 cold, does that sound about right? Or should I take the car out for an aggressive drive, and adjust the warm pressures down to 26/29 and then leave it. I'm talking about pressures for road, not track here.
I check my pressure before every drive, but if your car is a daily, I can see this as quickly becoming impractical. Wouldn’t it be convenient if those TPMs actually gave a pressure readout. Surely it wouldn’t have been hard to do?Yeah my gauge is a good dial type and has been verified/calibrated.
Thing is that 26/29 "cold" in Italy is different to 26/29 cold in the middle of winter in the UK. There could be 20 degrees celsius difference in temperature there.
On a track this is easy. Heat up the air in the tyres over some laps and then bring the pressure down and you're doing everything on a single day. On the road when ambient temperatures are changing etc, it's not so easy to be consistent. You'll adjust cold pressures to whatever the temperature is one day and the next day it might be completely different.
I bought Michelin ps AS+3 and I am happy with them. They are not for racing around, but are nice. Had to upsize one size on the 18-19 rimsis there a best all season tire for 4C?
not a snow tire just that it still drives in the winter cold temps?
Thanks will look in to itI bought Michelin ps AS+3 and I am happy with them. They are not for racing around, but are nice. Had to upsize one size on the 18-19 rims

Hi Chimera, I’ve run Conti 5’s for a few years until recently on my 147. Good in the wet but soft and I got no more than 2 years and 20,000km out of a set of fronts. I’ve changed to Michelin PS4 tyres and find them more sophisticated. Quieter, smoother riding and with plenty of grip. The softer, more compliant nature of the Michelin’s might be a reason why some didn’t like them coming from Pirellis. I digress, that’s why I’d go for Michelin Pilot Supersports if you can. Just an all round more sophisticated tyre than those track focused ones. Those track focused ones are noisy to the point of seeming like you’ve got stuffed wheel bearings, at least that’s what my Hankooks sound like. The Supersports will have plenty of grip and be a generally more rounded Tyre, pardon the pun. I think the RE71R’s would melt in our summer temps.Folks, thoughts on best out of the following in 225/40R18 and 255/35R19 or perhaps 265 as per comment in another thread. These are on 8 and 9.5 “ wheels, not stock.
At present I’m looking at Yoko AD08, Michelin Cup 2 or Michelin Super Sport. Unfortunately 4S not available in 225/40R18 here. Unfortunately AD08 is non R version here. I don’t track so Cup 2 wouldn’t be good choice for wear and wet weather. That leaves MSS which while good is hardly cutting edge, or best anymore. I might look at RE71R but any other suggestions? How are Conti 5s?
I think the Kumho Ecsta PA51 is a great high performance all season tire. It is the next generation of the 4X/KU22 that I had and was very happy with that tire.is there a best all season tire for 4C?
not a snow tire just that it still drives in the winter cold temps?

Agreed......one of my other cars is a 2018 GMC Acadia Denali SUV. It has pressure readout that is very accurate on each tire. I can use the dash info display to show the pressure at each tire.....or log in via an app on my cell phone to check it remotely. If a tire loses pressure it will aIso alert me as the 4C does. I also get an analysis report from GM occasionally on email that gives lots of diagnostic info including the tire pressures when cold. That information is useful and a good use of technology.I check my pressure before every drive, but if your car is a daily, I can see this as quickly becoming impractical. Wouldn’t it be convenient if those TPMs actually gave a pressure readout. Surely it wouldn’t have been hard to do?
They are good but noisy. If that doesn’t bother you at all they are an excellent choice. They are excellent value, being relatively cheap, at least they are here in Oz. Masses more grip than those Pirellis. I’m putting mine back on soon for a track afternoon at the start of next month.For my 17/18s I am going to try the Hankook RS4s next. Supposed to be really close to RE-71Rs for performance and last 4 times as long.

Even my 2016 Abarth 500 has pressure readout for each tire. Wish there was a way to "alter" our display to show actual pressure and not "OK".Agreed......one of my other cars is a 2018 GMC Acadia Denali SUV.

As alfanut said, PS4 is my tip. Great tire for our car, but not saying a better does not exist. I had the Pirellis before PS4, that was night and day, both in the dry and especially in the wet. Have not tested the other brands/types commonly mentioned on my 4C, but have Goodyear Asymmetric 3 at my other two cars, they are great, but does not excel in the wet.Folks, thoughts on best out of the following in 225/40R18 and 255/35R19 or perhaps 265 as per comment in another thread.
