My car has a little over 17,000 miles on it. I just had to replace the front pair as they wouldn't balance, being worn unevenly towards the insides. So they're all basically new now with about 17,000 miles.

Is that about what I should expect to get out of the stock Pirelli run flats?
The treads were still very strong on the fronts. It was a more of an issue with being unbalanced ..... wobble, wobble, wobble!


Also, if the front wore unevenly, despite being new tires, that have been balanced and rotated, is there a chance that a misalignment might cause them to wear unevenly again?

17K is a pretty fair average for those tires. It seems we do need to watch our air pressure and alignments pretty close with these cars. My last set of non run flats only made it to 17-18K before they were at the wear bars. Hopefully these new ones (Michelin Pilot Sport A/S/ Plus) will fair better. I'm up to about 6K on them so far and they're doing fine.

Those seem to be about fairly average, my fronts are still in pretty good shape at 18,5 -- the rears are about ready to be changed though (worn in the center) -- I did readjust my tire pressure which helped trememdously. I run 27 cold in the rears and 34 psi cold in the fronts. That seems to be the sweet spot for the best wear and a respectable ride.

^^^ thanks!

BTW, I'm running them at about 30 psi BACKS / 33 psi FRONTS... in hot weather (88-98º)

This is about where I've been keeping them now. The recommended pressures are not correct.

I got 18K out of my OEM Pirelli Runcraps, and they were shot at that mileage. I replaced them and never looked back.

Do tell, do tell.... what did you replace them with? What improvements could be expected? I've got about 17k miles to "shop".

This has been covered in other discussion topics, but I followed the path of a lot of people and first replaced the Pirellis with Goodyear F1 All Season tires. They were really good at first, but got extremely noisy after about 10K miles. I, like a lot of others ended up hating those tires.

After 15K miles on the Goodyears, I replaced them with Michelin Pilot Sport All Seasons. They are more expensive, but they ride a lot better and have equivalent performance to the Goodyears. They are also very quiet. I got mine from Discount Tire and they havea 40K treadlife guarantee, so we'll see how that works out since our cars are known to eat tires.

So... the short is, I personally recommend replacing your Pirellis with Michelins. I'm happy with them so far, and I have about 7000 miles on them.
