"tires let loose ..... due to the car being light"
hmm now it sound like making something out of nothing - but if you are looking for an excuse to get lighter wheels/stickier tires, or lower your car, go ahead.

 

I’m on a 3-year, 36k lease. I fear I am going to have to replace all the tires just in time to give the car back.
I have a Ti Lusso with the 18” tires. I wonder if they will wear better than the 19” tires on the Ti Sport.

I have been doing 3-year leases for a long time and never once had to replace tires, but this is my first set of run flats. A large expense I did not plan on.

 

Run flats have nothing to do with it. Winter tires are an answer. Better seasonal performance and months of wear not incurred by the OEM tires.

 

"you know those roads"
oh, he doesn't just know them - he is the self described fastest guy to drive them in anything, in his prior mazda protege.
so one might guess this was something more than the simple normal vehicle dynamic of unweighting a bit over a crest - but apparently that was all it was, for "a fraction of a second".

as good an excuse to buy stuff you already want as any.

 

I liked his question. Gave me a chance to think about the physics and finally understand how unsprung weight works.

Hopefully he'll take our advice and buy great tires, longer springs, and a giant wing. I for one would love to see what a Q 4 rallycar looks like. Not even Bing sarcastic here!

 

No issues.. but does let go around some corners. I will make the front tires the same as back and see if any difference.. 6k miles

 

Not a good tire in my opinion, I have them on my X1. I have a goodyear runflat on my 5 series which is better. Read some online reviews before you get these.

 

Honestly, the P7's have been just fine for me. I have the 19" 5-hole Quad wheels. I live in the Rochester, NY area and we have our fair share of crappy roads thanks to longer, harsher winters. My Ti Sport Q4 is pretty much a daily driver (for leisure, I drive a Yaris to and from work and to the gym). Of course, I sometimes enjoy some spirited driving on some decent back roads, of which there aren't many. The Pirellis are fairly comfortable albeit providing some road noise at high speeds. Around sharper corners you may hear some brief squealing but the car's chassis and steering capabilities are so good they make up for a relative lack of grip. I've yet to try the Giulia on track but a couple of friends are pushing me to join them for a track weekend at Watkins Glen. They both drive BMW's and said I wouldn't need to get summer tires, unless I planned on using the Giulia on track multiple times a year.


All in all, my impression is that the P7 run-flats will be just fine and will last a decent amount of time with relatively regular driving and occasional spirited runs. I'm on a 2-year lease but I plan on purchasing the car anyway for sure. I'm about 3,350 miles in and the tires look brand new still even after a long road-trip through Canada and New York in which there was definite sporty driving involved. Seems to be a solid set of tires, if unspectacular I guess. I was also recommended the Michelin tires mentioned in this thread.

 

there is a great deal of traction (braking) uphill, much less when going down.

with brake by wire the pedal effort remains pretty constant, apparently hiding/masking fade even for guys doing track days.
unintended acceleration, must be an audi (driver).

 

My impressions of the OEM Pirelli Cinturato P7 all-season grand touring run flat tires on my Giulia Ti AWD is that they suit the character of the car very well. They offer plenty of grip for spirited driving on public roads. No, they are not like the extreme performance summer tires I run on my Miata. And that's fine as I have rare occasion to really push the Giulia that hard anyways and doing so on public roads is rather irresponsible, never mind the non-defeatable ESC/TCS and the immense grip already afforded by the Q4 AWD system.

My biggest gripe is the poor tread life (at 15k miles I'm down to the wear bars) and the fact that none of the official Pirelli dealers in my area understand the official Pirelli warranty policy and they don't want to deal with OEM tires for run flat road hazard warranty adjustments (even though it's their job). Alfa dealers aren't official Pirelli tire dealers so they can't pro-rate the cost, either. So far I've spent nearly $700 on replacement tires in my first year of ownership due to road hazards, which should have been less than half of that cost if only I could find a Pirelli tire dealer willing to administer the warranty. Which is why you pay twice if you have the Mopar road hazard insurance that the dealers can administer.

 

Also, not sure if it's already been discussed here, but the P225/40R19 93V XL Pirelli Cinturato P7 RFT is available in two variants: AR for Alfa Romeo and Star RSC for BMW. I don't know what technical differences exist between the two. The price difference is $13.50 per tire, with the AR version being the more expensive one.



For BMW the star notation may be used to bring used vehicles to CPO status. If the vehicle does not have the star on the sidewall then the vehicle will need new tires to be CPO. It can also be used to determine if a tire has been replaced with a non-OEM tire for warranty claims without having to run the Tire Identification Number (TIN) through the information system.



Has anyone installed the BMW Star RSC variant on their Giulia instead to save a few bucks?
