I have a few questions about tires. If anyone has replaced the tires what brand did you use? Also, if you did replace the tires did you get run flat tires like the original or standard? If you got non run flat tires, how would compare the ride quality and performance? Lastly, does anyone know if the car can be turned in at the end of an Ally lease with standard non run flat tires? FYI, my car has 18" tires and MRC. Any information that you can provide will be appreciated. Thanks.
Replacement tires

Before picking up my car, I had the dealership remove the factory tires and install Blizzak's. These are not run flats but no problems here. For snowy western ny weather, I'm sure the Blizzak's are going to be a much better than the factory all-seasons. I didn't get much road time on the run flats so I can't compare the ride but winter tires always seem a bit squishier compared to all-seasons and summers. No clue on the lease but I don't think it's going to be be issue.
When turning in a lease car you must return it with comparable tires. If it came with run flats, it must be returned with run flats. If not, you will be charged to replace the tires. If you want to change to non run flats, save the original tires an put them back on when you turn the car at end of lease.
I put Blizzak LM25s on for the winter as well. Ride is decent - not as firm as the 19" runflats I had on in the fall.
As ctspaul said - if you are leasing and don't return the car with runflats the dealer will ding you for sure (unless you lease or buy another car from them)
I just purchased a new set of tires for my 2014. That does not sound bad until one realizes that the original tires only had approximately 12,600 miles on them. They were VERY noisy and made a thumping sound that changed with the speed of the vehicle. As I stated in another thread I was fairly certain that it was a bad wheel bearing or, rotor, or something else. It turned out to be the tires. Not only were they "cupping" which caused the thumping sound and general noise; the tread was down to 3/32". At 2/32" they would not pass inspection here in Pennsylvania. So, since the car was just aligned and since Bridgestone was offering a $70 rebate in April, now was the time to change. I went with the Bridgestone Drive Guard run flats. I did this because the car is leased and I did not want to take the chance that there would be a problem when it came time to turn the car in. Otherwise, I would have purchased regular tires. I only have a few hundred mile on the new tires but there is a significant difference in noise and ride comfort. However, that it to be expected with any new set of tires. FYI, I contacted Pirelli regarding the original tires and as I suspected tire warranties are not worth the paper on which they are written. The problems are always due to something the owner did or did not do. I was even told that there is not mileage warranty on original equipment tires. Just for information purposes, you should know that I had the original tires rotated three times and I checked the pressure once a week or so. Still, Pirelli states the problem was mine. Never again will I purchase a Pirelli tire. I am curious as to the experience others may be having regarding these tires.
I'm at about 12,000 miles and still have a fair amount of tread left, they were about 50% at 10,000. Seems to me like your car was out of alignment for a while particularly since my tires are summer only and usually last about 18,000 miles. Pirelli treated you the same as any tire manufacturer would in my experience, cupping and excessive wear are almost always alignment problems.
Some tires are more prone to cup than others even with a same alignment setting. cafpaf, if there's no mileage warranty on your tires, I assume you have the summer-only set. Vsport tires does not come with a mileage warranty (I had similar issues with mine). I had to check the warranty info myself on tirerack to verify that dealer claim. For a matter of fact, most summer tires (Michellin come to mind as an exception) do not come with the mileage warranty.
Do you have Magnetic Ride Control? How much hard cornering are you guilty of? (I'm guilty of a lot). Did you ever rotate your Pirelli's? I would normally doubt that any name branded tire would cup, but RF tires may be different in that regard.

Interesting. I have noticed my Pirellis getting noisy in the last week or two. I am at about 14,000 miles. No vibrations, though--other than my rough idle.
To clarify a few points about my former tires. I had the 18" all season version of the Pirelli's that came standard on the luxury version of the CTS. I have Magnetic Ride Control and had the tires rotated three times in 12,600 miles. No hard driving or cornering ever! Checked the air pressure every week or two. These are all reasons that I do not understand why I had this problem.
Add me to the list of cupping Pirelli tires. My CTS has the 18" 245/40/18 Pirelli P Nero All-Season tires--car has 12,200 miles on it and it has become very noisy. Tires were rotated at 6,500 miles at the Cadillac dealership. All 4 tires have decent tread, but the fronts are cupping badly. I do have MRC.
Funny story, I stopped in the dealership today to show my service advisor. He called a technician over--the tech said that a customer recently came in with the same issue and customer had to buy a new set of tires. They suggested rotating them and that the cupping would flatten out? I set up an appointment for next week and get on the road for work. I call Pirelli while on the road and Pirelli is no help--they won't warranty OEM tires. Pirelli blames my driving, Cadillac, the weather, the roads, rotation of the Earth, etc. so, I hang up with Pirelli and keep driving. I end up hitting a monster pothole on I-90 in Buffalo near Orchard Park exit and blow out the front drivers side tire. Cadillac Roadside finds a Caddy dealer with a tire in stock and I decide to drive there on the run flat (never driven on a flat run flat before). Cost me $350--and I'm writing this from the customer waiting area of West Herr Cadillac/Buick/GMC.

I dumped my Pirelli Zero run flats and put on Michelin Pilot Super Sports. They are fantastic. When my lease is up the dealer will get the OEMs with about 5k miles on them. I carry an air compressor and can of slime if I get a flat.jbonacci said:
Do you have magnetic ride control?
Yes. I even wrote in my post that I have MRC.
Guys, all the dealer claims about lack of warranty on all season tires and asking owners to purchase new set of replacement tires seem very fishy to me.
GM/Cadillac went through a conversion where tire warranties are administered by the dealer as the part of bumper to bumper warranty. I actually have used this service where one tire of my Escalade could not be balanced and was found out of round. I received a brand new tire and install courtesy of Cadillac. On another occasion, I had badly cupped front tires on my STS. This happened around 16k miles. And although Cadillac pointed out that I needed to rotate my tires more often and really need to check on alignment every 12k, they offered 50/50 split on the tires.
Standard 18" all season tires, as long as they are rotated properly and even with slightly off alignment setting, should not cup to be point they should be replaced around 12k miles. And being an all season tire, they should have warranty which I think Cadillac would...should...honor.

I am going through this same situation right now with my dealer. 2014 CTS Pirelli run flats have been absolutely horrible. My Caddy is actually louder than my truck now. I can't even use my Bluetooth, i'm about to loose my marbles.My last visit (they had my car for almost a week) they said that i must endure through one more tire rotation/oil change and then they would "revisit" the situation, whatever that means.
Not to bash but run flats are a major negative in my mind (short life, rough ride, overall expense). It was a reason for me not to
consider new CTS. (Had a lot of run flat experience with BMW). Have 66,000 miles on noral Michelins supplied with my SRX with 5/32-6/32 remaining.
On my first second gen CTS, Caddy offered to replace tires (Goodyear RS I believe) because of cosmetic bulges that 'did not impact safety'.
In my 40 years of driving I have had two blow outs. Both on these Good Year tires. The second blow out (on replaced set) showed
absolutely no signs of impact damage /or penetration and blew out while driving 70 on the interstate. Sent to Good Year for evaluation
and they said they were fine and destroyed them
