I've done this exact swap (nearly). My Challenger came with all season Pirrellis and swapped to a Michelin AS4. I recognize that there's a huge difference between an 800hp V8 car at 5,000lb vs. a Nissan Z with 400hp at 3,700lb. However, the tire compounds are pretty much the same.

I'll just say that if you think your Potena S007 is a doodoo tire, then the new Pirrelli might actually be worse. The Pirrellis are notoriously hard tires. To get them to perform any kind of way, they have to be excessively heated up. Wet weather performance is a punchline, as I have felt safer on some drag radials than on Pirrelli all season tires. Again, they're extremely hard and they don't communicate pretty much anything to the driver other than the excessive humming tire noise. This hard nature affects both the cornering feel as well as braking and wet weather traction. If you do some research, I think you'll find it readily apparent that the Pirrelli tires tend to have sudden loss of control issues with wet roads combined with increased lateral load (aka, hard turns in the wet). And no, I'm not talking about rear slip, but the fronts. On one occasion, I was navigating a round-a-bout in the Challenger at around 35mph. The car hit a puddle, lost all steering and glided right off the road. This occurred when the car had around 800 miles on it. The Pirrellis were gone before 1,200 miles.

Thank you, I really appreciate the thorough first hand experience with both this tires. When I replaced the shit Dunlop Sport Maxx RT that came factory on my 17 Subaru WRX STi Limited to the Michelin Pilot Sport All-Season 4, it instantly woke the car up in regards to confidence, the Michelin PSAS4's give you very good feedback without being overbearing, fairly good road noise. I think Imma ditch the Potenza S007 on my Z and replace them with the Michelins. Again thank you I appreciate the fedback.

Any recommendation for tire pressure (psi) for the front tires 255/35zr19 and rear tires 305/30zr19?

I have upgraded my tires and don't know what is the correct tire pressure.

Thanks!

FWIW.

I bought the lmrs1 wheels (bronze w/ staggered set up). I wrapped the them in Firehawk Indy 500s. I've been happy with them.

The tires are sticky. Note, I never have driven the car in the rain (I know, I'm that guy), so no comment on their wet traction.

When I get a second set of wheels I'm going for the Firestone Firehawk 500 for the Spring-Summer season. I've ran these on my 86 for almost 5 years and they haven't skipped a beat. Excellent wet weather rating, and pretty good grip as well. May not be the top 3 stickiest tire but just right for the street. They last awhile too.

This is a bit of a loaded question. I would say that you should probably start at the car's factory recommended cold tire pressure that's printed on your door jamb. That should say 32 front, 29 rear. The tire compound or manufacturer itself shouldn't factor in too much unless you have a drag radial or some other kind of specialty tire. This is assuming the tires you bought match the OEM load index specification (they should, or your tire guy should be lit on fire). The factory is calling for that certain PSI mainly for optimal load handling performance. You can safely operate the vehicle outside of those parameters to some small degree, but there's pros and cons of doing this.

The Firehawk Indy 500 is a great tire for the money. I'm a diehard Michelin fanboy (dad was a Michelin tire regional exec back in the 70s/80s). But as a driver, I've used lots of different tires. The Indy 500s don't inspire me in the wet at all. In terms of handling and launch grip, I'd put them just out of the top 3 behind a Nitto and behind both the Michelin PS4S and the PSAS4. Yeah, I said an all season Michelin is better than a Nitto summer tire (because they are ).

But the Firehawks are a LOT cheaper than Michelins. I only get tires once a year during my local Mavis' memorial day buy 3 get 1 free sale. That way it doesn't hurt quite as bad when buying 2 sets of PS4S tires, heh. The Indy 500s are definitely a competent tire. They're a little loud, but they look cool as hell. Love the tread pattern. If I were building a show car, I'd paint a white letter design on them and they'd look stellar. The prime reason I don't use them though, is they develop traction fade too soon for me. Most high end tires will go 80-90% of their tread life before they lose 30% of their traction/grip. The Indy 500, like Pirrelli P Zeroes, start to get noticeable traction fade at around 50% life, and by 30%, they start to feel BAD. So, while they can technically be driven more, you stop being able to have fun on them long before the tread's gone.

These are my same thoughts on this tire!

If you want to get REALLY specific with tire pressures they’re dependent on the load rating and weight of the front and rear of the car. If you end up with tires with different load ratings than stock, there are calculators online that allow you to plug in the OEM info, and it will adjust recommended psi.
