Funny...i have nonRfs and the other day i noticed i had a slow leak (per DIC) in my left rear. Turns out to be a nail (head was shaved off). I do have a small portable pump and so for the last two days until I can get a spare (got one from tire rack) I have to pump my tire before I go to work. I thought of patching the tire but where the nail is at its just on the side of one of the tread and groove. Worst case I'll patch it later and use it as a spare. Kind of an inconvenience...

Many have reported a small loss of MPG too,,just thought I'd throw that out there as well!! My opinion Goodyear run flats:ack:,,Michelin's:thumbs::thumbs::c heers:!!

I have a question??
 

Michelins appear to be the front-runner-Now the question? Does the C5 come with a lug nut lock key to remove wheel? I haven't found one if it does!

Look under the drivers side, rear, lower, compartment under the hatch. Lift the cover and a key should be tucked in there. If not, drive a socket onto the lug, remove it and replace it with a regular lug. That is after all, all a thief would have to do to rtemove it. :)

No Locking Nut Here
 

I do not have a locking nut on any of my wheels and am reasonably sure the car (2004) was stock when I got it. Bottom line, you may or may not have a locking nut and the only way to know for sure is to look. If one came from the factory the key is located as posted above unless, of course, somebody used it and did not put it back.

I can't agree more with the improvements of the Michelin AS ZP Plus tires offer. After a lot of research I replaced the original Goodyears and the difference was huge. The Goodyears had next to zero traction especially when the temps dropped and were LOUD all of the time. The Michelins made a huge difference - quieter and the grip is amazing compared to the original Goodyears. I did appear to lose some mpg but that is the only down side that I have seen.

The Michelin PS ZP's (or AS ZP's for all season) are the absolute best runflats you can get. Period.

However, despite some claims here, you can still get better tires in the non-runflat catagory for less money. For example, I just changed out my Pilot Sports ZP's for some Nittos and the difference was remarkable.

This is not ragging on the ZP's, just know that there are better tires out there.

who knew?:rofl::cheers:

Sorry, my computer was down and out, bad hard drive. You are right, my air pump has a light on it, plus I carry a headlamp, so I don't have to hold a flashlight.
Many moons ago I wrote up a Tech Tip on the tools I carry, it seems to have gotten lost.:cheers::flag:

Another vote here for the Michelin AS/ZPs Like Jet Jock said, night and day difference over the Kuhmo RF that were on it when I bought. mine were $1000 out the door.

Michelin AS/ZPs are on....incredible difference over the GY run flats:thumbs:

Michelin AS/Pilot
 

While I am happy with the noise improvement over the GY F1s (1997 C5), and the performance is good, I am not crazy about the look. For a "Low Profile" tire, seems to look (FAT). However, I live in the Northeast and feel more confident with the AS Tire in the rain.

On my second set of GY runflats. LOVE the look, don't mind the ride or noise at all. It's a sports car, not a Buick. Besides, my right foot and music drown out all the tire noise anyway. LOVE the runflats! Gotten flats twice in 5 years. WONDERFUL to just drive the car into the shop and get it taken care of.

... still not seeing many reports from those running the PS2 ZP.

I'd like to hear comparisons of the Eagle F1 EMT to the Pilot Sport PS2 ZP.

Bigger issue....I just bought a 2003 in 2013.....with tires made in 2002...Originals!!!!!!!!!!Museum??:rock:
OMG:eek:
I guess the need for a flag on the rear end was more important than safety..:hide:
In God We Trust but WTF.:blueangel:

Please remember how to read DOT codes indicating year tires are born...
We can argue about how many years they really last...:iagree:
I say 5...some say 7 none say 10...:lurk:
HellO:ack:
Just sayin':crazy:

I know 3 year old thread..:spit:

Wish I'd had this information when I purchased my Michelin run flats a couple months ago. I would have gladly paid the price of this spare kit and purchased non run flats.

I have been running the pilot a/s sport zp runflats for three years now the tires come with a 45,000 mile warrenty and so far with 37,000 on them it looks like they will get the 45,000 plus another five before i will need to buy new ones i have no complaints with these tires they are much better then the goodyear run flats that came with the car...i will probly buy them again when the time comes...

According to Google:
UHP stands for Ultra High Performance and refers to a tire meeting the following requirements.
* Rim diameter : over 16 inches
* Aspect ratio : under 55
* Speed rating : over 'V'

Don't know what MP means.....and it was NOT a dumb question.
How about:
