They aren't bad, but they are an all season tire so performance is limited versus a summer tire. I can't say I have too many complaints with them overall. I can get mine to sing a little bit in the corners when I'm driving spiritedly but that's expected.



I've got 9k on mine, I did just have one replaced due to a nail and the others are wearing fine/evenly. I don't see you having to replace them within your lease.

 

I've got these tire on my 2017 Ti Q4 and have zero complaints. I live in CO where a lot of the city roads are absolute garbage and they seem to have no problem standing up to the rough roads and occasional potholes (I do make an extreme effort to dodge them as much as possible). As far as performance driving, again, I've had zero complaints. I can consistently pull upwards of 0.8g's without any loss of grip. Now I would give some of that credit to the Q4 system, LSD and adaptive suspension, but at least in this configuration the tires are by no means a weak point in my experience. However, if you go with RWD, I cannot attest to whether or not there is still enough grip with these tires. We are about a year into our 3 year lease, and I have no doubt they would last all the way through your 2 year lease even I'd you do some spirited driving often. As long as you're not at the track all the time, wear shouldn't be an issue from what I've seen. So like I said, Q4 with performance pack works perfectly with these tires (and being in CO, it works awesome in snow too) but again I can't attest to the same without those other options working to maximize the performance of the tires.

 

These are my sentiments as well, but I do find the tires protesting at about .8Gs I definitely don’t feel as comfortable exploiting these tires beyond that. I may go with a set of summer tires soon.

Overall, these are suprisigly adequate tires however.

 

Q4, Cinturatos, San Diego (so weather always the same.).

Off camber left turn on way to work.

Cinturatos, 400 miles: ~0.87g typical
Firestone Firehawks, new: ~0.97g
Firestone Firehawks, broken in: ~1.0g.

For 600ish installed, this was a no brainier.

Physicist hat on:


With unsprung mass, your dampers have to fight against the inertia of the mass. So- hit a bump, and the wheel rebounds. The damper must now exert a force on the mass; the lower the mass, the faster the wheel is returned to contact with the ground.



However, for rises and rolling hills, the time constants are very different. On the rise you're discussing, it's likely that the wheel is being damped down at a similar rate to which the rise is falling away. What this means is that on more gradual rises, the unsprung mass will have a much smaller traction effect.


Finally, there's the brute force, always correct solution: moooaaaarrrr downforce! How you get there on the giulia, I don't know.

That’s an interesting question, I wish someone with knowledge could chime in. Unsprung weight, on the whole, can slightly increase traction, but slightly reduces acceleration. But when you unload the car over the rise, will the heavier unsprung weight tend to increase the force lifting the wheel? This is likely a function of the spring rate, which it seems, would be less effective on the higher mass unsprung, after movement began, however the higher unsprung weight would resist unloading slightly longer and be restrained from starting to move slightly longer?

 

Finally, there's the brute force, always correct solution: moooaaaarrrr downforce! How you get there on the giulia, I don't know.

Ew, ew, oh, Mr. Kotter...Mr. Kotter...

Get fat, like me?

 

I’ll echo the above sentiments: they’re pretty good. Sticky enough to do what you want on the road this side of hitting turns like Lewis Hamilton, at which point they will howl and squirm a bit, but will remain predictable.

I have found the Alfa spec front pressure to be too low for my tastes, and do run them up at 37-38psi to match the rears. Feedback and stability seem a little better, and they don’t howl as easily when pushed in the +.8g range.

I’m only at 5k miles on mine, but they look good tread wear-wise. I’ve got to get them through two years/30k miles only.

 

13,000+ on P7's, didn't believe they were run-flats at first because they rode nicely. Squeal like excited school kids if you push them, but wearing just fine.

 

thanks guys. Looking forward to finalizing my lease soon and picking up the car! going with Q4 Ti Sport. so I'm probably good to skip any wheel/tire warranty? especially because tires seem to be covered anyway...

 

I got the warranty on mine. Low profile + Michigan roads make it worthwhile. I've already had one tire replaced.

 

They're average all-season tires, and don't do sporty cars justice.

I noticed tread squirm in fast corners, that they tended to suffer from sidewall deformation at speed.

Once I had replaced them with Continental DW summer tires, it was as if I unlocked a new level of performance.

If you have to have a sport oriented all-season, look at the Michelin A/S3 +

 

I miss my Conti DWs. Got 38k out of them on a slightly lowered MB W210 with Koni Yellows. Rode on rails and I couldn't break them loose without cold pavement under them (when I lived in the eastern half of the country).

 

I'm probably going to forego the wheel insurance (unless I can get it for like $300) because I don't hit many potholes even though I am in NJ... hopefully nothing happens

 

double post having issues deleting

 

Are they expected to last though a 2 year 10-12k/yr lease?

I have 24,000 miles on my Giulia and the tires are still fine for probably another 5-10K miles. I had to replace one of the tires because of an unrepairable puncture. The single new tired had to be “shaved” to make sure it was the same diameter as the other three because I have the Q4 and performance package.

 

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

 

If you want performance tires stay away from runflats. Check tire rack they have alot of tires tested.

 

Not sure I agree with that statement; I have the Michelin Pilot
Sport run-flats on my Corvette and they are a phenomenal tire plus peace-of-mind.

 

P7 are basically all season grand touring tires....Giulia’s handling is so good that it in many ways masks P7s deficiencies....I think they are perfectly fine for everyday use....I will eventually replace them with high performance all season P Zero Nero in runflat version, they are much better AS tire with still very low wear....I contemplated going to non runflats where there are more options but the hassle if you have a flat (I had one slow leak so far on P7) is just not worthed the trouble when somewhere on the roadtrip

 

Are you guys driving with the same tires I've got? 225 40R19 Centuratos on a Q4. I have yet to hear anything but a little road noise from the tires, in spite of getting a little bit sideways and frequently pulling about 0.85 gs (on the center display) in turns. I hear a little ABS chatter when I brake very hard, but nothing like a squeal.

I inflate to 33PSI front and 34PSI rear (lower than on the sticker). This seems to quiet things a little and provide a little more grip. Also, I do my most aggressive driving above 6000' elevation while I check the tire pressure at sea level, so I probably have slightly higher than the recommended pressure once I get going.

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%) .

 

I don’t have these on my Giulia but do on my 2014 BMW 328i xDrive. They’ve lasted 40000 miles so far. And roads in the Boston area are bad. Of course this is on a daily driver car. Had to replace one tyre because of a pothole but i drove on that “flat” tyre for 150 miles until I had the time to get it replaced. I’d say if these are what came with your car, leave them on, especially if it’s a lease and you aren’t doing constant spirited driving. Here is Boston there’s hardly any time of day where there no traffic to do that.

 

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....

 

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 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.

 

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.

 

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

 

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

 

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

 

get longer springs.

 

Lockem, much of what you are describing is fixed by right dampers not springs....realy good stuff has separate damping and rebound settings for low, high and mid changes....active suspension probably takes care of lots of this automatically but depends how it is calibrated, it most likely still can not handle very sudden, high speed changes.....since bikes have only two wheels such sofisticated dampers are very common on pretty much any performance bike these days....baja cars even have two dampers on each wheel to cover for the extremes of high and low speed damping and rebound as well as travel....

 

I have the active suspension and had it in D-hard--lots of random curves and reasonably smooth pavement in that section of road. Perhaps it would do better on the soft setting?

I don't hear the thud of the suspension hitting the stops and the car certainly was no where near airborne (I still had quite a bit of traction, just less than I am used to), so I don't think more travel is the solution. Of course slowing down would help (the sight line is not very good, so maybe a good idea to slow down?), but where is the fun in that?

Actual speed is in the 40-50MPH range.

 

you need the downstroke to keep the wheels (loosely) on the ground when the rest of the vehicle is going up.
