P zero nero are pirelli's high performance all season run flats, continentals are dws, and the michelins have been mentioned often.
it's not quite accurate to bag on run flats or all seasons if your complaints are based on the touring/lower performance versions.

with super low profile tires, designed to reduce sidewall flex being the standard for performance tires, I'm not quite sure why people would decide a tire with an extremely rigid sidewall can not be a performance tire.
maybe not a race tire, maybe not the fastest track day tire, but ....
a less comfy ride seems to be the biggest drawback to RF in daily use, balance that against say, Boston where the breakdown lane on the freeways is utilized for traffic during rush hour, or other situations where you might not want or be able to stay where a flat occurred.

Guys,

Can non run-flat Centuratos be ordered on the cars? Just wondering if ride and handling would improve (could always throw a tire inflator kit in the car...I have read good reviews on the tire at Tire Rack and just like the idea of an Italian tire on an Italian car) - I remember my Pirelli P-6's on my GTV-6 and it was really a great tire but of course, that was donkey years ago....

 

[chaadster]

I don't think Pirelli offer a higher performance, runflat, all season tire in the stock Giulia Q4 19" 225/40 sizing. I checked their P Zero and P Zero Nero lines but didn't see any.

Other than Goodyear Eagle F1 Asymetric 2's, which runflat options are there in the stock sizing?

I am planning to switch to 245 35R19 Michelin A/S 3+ non run flat mounted on 19x8.5 Tecnicos in a couple of weeks. We will see if that yields the extra 0.1gs of grip and maybe 10 feet less braking distance from 60MPH that tire rack claims.

255/35R19 is a better match (-0.23%) for overall diameter to the factory 225/40R19 than 245/35R19 (-1.28%) .

From articles I have read the most impact failures occur with the lower profile tires on the 19" rims. This makes sense to me. I think if you have the 18" or 17" wheels you should not worry too much.

I couldn't resist the 19" because the MSRP of the Misano blue Ti Sport I saw was cheaper than the Base Sport Misano blue I was looking at lol... it came with a bunch of driver assistance crap

hoping I can score insurance for cheap

 

[spiders]

no issues with the wheels? that document I posted said the tires were covered already but not completely sure

The coverage I bought covers both the wheels and tires, the recent replacement was due to a nail so that was covered without issue. I tend to buy the wheel & tire coverage as OEM wheels aren't cheap steelies anymore and replacing them tends to be costly. It's worth buying the coverage to me just to cover my butt just in case.



I've had to use the coverage at least once on my last 4 cars.

225 is not an accurate measurement, as the width varies between manufacturer.

You need to go on TireRack and use their 'Tread Width' value to accurately match wheel & tire fitment.

Example:

A Continental tire in 225/40-18 has a tread width of 7.6", and my wheel is 18x8.

This is optimum fitment, it preloads the sidewall with a mild stretch that enhances agility.

A Michelin tire in the same dimensions has a tread width of 8.1". This is a bit too wide to be ideal.

I know it has been answered by other members but, in my experience, these P7 are good daily driver tires with good wear and acceptable comfort. Sometimes, a little bit noisy but it does not bother me. As for use in track days, I found them less than ideal, although they are predictable and provide a reasonable feel.

These (P7 Run Flat All Season) were also the tires that came with the Mini Cooper S that I use as a dedicated track car. They feel the same in the Mini: not a lot of grip but predictable. They are also pretty safe in wet conditions. However, when I had the opportunity to drive the Mini few months later, in the same track, wearing PZeros (also Run Flat but Summer Performance), my lap times were about 1.5 seconds lower. Much more grip and still predictable. Of course, it is all based on what you want from the tire: performance wise, it is not fair to compare a Grand Touring All Season (P7) with a Max Summer Performance (PZero). On the other hand, thread wear was WAY better on the P7 and, when I took my Giulia to the track, the tires still looked really good after almost 4 hours of track time.

Finally, I got the tire/wheel warranty, which included also key fob replacement and paintless dent removal for $799 (5-year coverage with no deductible). I always get these, mainly with a large wheel that I love... I had three wheels replaced in the past with other cars when I lived in Michigan (pothole land). And this was a great value considering how expensive these 5-hole dark wheels are.

The P7 are fine for what they are (middle of the road all season tire) but nothing near as good as a high performance summer tire.

 

[lost1750GTV]

what brunocav said - if you are going for lap times/position, yeah you want sticky stuff, with the downside that they get eaten up.
most people are better off with a predictable tire that lasts a little/lot longer - and doesn't allow/encourage you to eat your pads /rotors if you venture out for a track day.
of course there could be a situation in your daily life where you wished you had the stickiest tire for that particular moment, but you aren't going to know if it's going to be hot or cold or wet or dry until it happens.

 

[Tony Bonanno]

I've been reasonably pleased with the P7's on my Q4 Ti with Performance package with 19 inch rims. 225/40-19 on all four corners.

Wouldn't mind a slightly wider stance on my Alfa though. Anyone have any thoughts on what the largest size you can safely put on the standard 19 x 8" Alfa rims (5 hole style)? Or best to leave it as it is?

Thanks!

Tony

My bad. I came from the land of 4 rings where the 19" wheels are 9J instead of 8J and can use the wider tires.

 

[Azure]

Do you guys think I will have no problems with treadlife after 20-24k miles for a 2 year lease? I drive not like a granny but no track work for this car. I know run flats have less wear

It's not the wheel, it's the tire.

A 225 tire from Bridgestone, Continental, Michelin, or Pirelli will have different tread widths.

Match that width to be ~0,5in narrower than your wheel measurement (19x8, etc.).

You will have no problems even if you like to push it here and there...grand touring tires have a very low wear....this type of tire would last 40k if you drove like a granny

Where do you live? If someplace cold and snowy, fitting winter tires for part of the year will help ensure the OEM tires survival. And if miles are left on the snows, you can use them on your next Giulia or sell them.

New Jersey so it does get decent snow. That is a good option. I will see where I am at this winter. I am in the document sending process now and will be picking her up at the end of the month

I had snows on my Saab when I lived in northern NJ (Bergen County), mostly because I often traveled north and west from there. Of course they also came in handy close to home.

Congrats in advance.

255/35R19 is a better match (-0.23%) for overall diameter to the factory 225/40R19 than 245/35R19 (-1.28%) .

But 255s are wider than ideal for 8.5" wide rims and the difference is small in either case. Even 245s are a bit wide for that rim. Tire rack reports the tread width of Michelin 245 35R19s as 8.8 inches. Ideally it should be a tick less than the rim width. The 255s have a tread width of 9.3 inches according to tire rack.

Michelin A/S 3+ in 245 35R19 is available non runflat as well as run flat. The former weighs in at 25 pounds while the latter weighs in at 28 pounds. The weight alone is expected to be enough to make a noticeable difference in ride quality and handling.

Compare with the Pirelli Centuratos in 225 40R19 RFT weighing in at 25 pounds.

Now if something better than a square set of Tecnico front wheels becomes available I may change the set again, but there is nothing on the horizon right now. The closest is Forgeline 2 piece with carbon fiber barrels (presumably very $$$), but Forgeline is unresponsive to inquiries.

In spite of being light weight, I believe the Tecnicos are better 19" winter wheels than the 5 holes, since they bend rather than shatter when abused.

are these wheels prone to breaking? what do you mean by abused? I have the wheel warranty but if I end up buying out after the lease would bring up some concern. I would probably ditch the run flats then anyway. I haven't seen any posts about these wheels shattering or cracking.

If I don't hit any major potholes should I be OK? like can the wheels/tires handle normal bumps in the road
