It's up to the local dealer. Some say they will swap the run flats out. Mine didn't. I did replace the 19" run flats with Michelin A/S 3's and they are about 674% better. Ask you dealer
My understanding is that RFTs are standard on the Q50 and the only thing they ship them with. If the dealer decides to help you out in any way, that is on the dealer. Mine refused.
Don't think so. In my case I bought a set of 19" Bridgestone Turanza Serenity Plus
High Performance 245/40R19 tires from Costco for $288.99 each. Also bought a set of OEM Infiniti rims on e-bay. All this to replace the 17" run flats that came on my pre ordered Q50 premium hybryd. (not the S version)
The dealer in my case had no clue so I took it upon myself to do all this. After all that I had to buy a spare OEM tire on ebay because the dealer has no clue on ordeing a spare tire package. (much less trunck space in the Hybyrd now with spare)
The car with these tires runs super quite, & smooth as silk on the road.

Be careful if you lease your car. Some people on this forum have indicated that you must return your car with the run flat tires so swapping is not an option. You have to buy new tires and store the old ones until you return the leased vehicle.

Where do you put the spare in your hybrid? If it does fit in the trunk, I assume you have no plans for a vacation.

What have you noticed that is different (ride wise) with the Michelin A/S 3 vs the 19 run flats? Are the Michelin A/S 3 cheaper than the stock tires?
You went with a good choice for tires I had a set on my G35. They are confortable and still has performance, equvilent to Michelins quality but not the price tag.

Really???
Initially I thought the RFT were decent, but after finally driving the vehicle for 3 consecutive days I'm starting to notice how much they suck. So I guess I have to go 3 years like this... I refuse to add anything additonal for a car i'm going to return.I would say if you plan on staying with Japanese sedans for a long time then you might as well buy your own set of wheels and tires, so even after your Q50 lease is up you have a set of wheels you can still use on another car.Really???
But I don't know if it will make much sense since you are paying for it.
Plus if you return a car with tires in new condition while the car has thousands of miles on it, they will question it.

The A/S 3's are a much smoother ride and way quieter over bumps. As a bonus they handle better too.. And yes they are much cheaper than the 19" run flats.

For the most part we (my wife and I) have been enjoying the new Q50 Premium with added 19" wheel package, but I must AGREE that the run flats are noisy and ride extremly rough, especially on the highway for a car of this class. I asked the dealer to swap them out during negotiation, but they wouldn't budge.
I'm wondering what the tread life is expected to be on these Dunlaps RFT's under "normal" day to day driving conditions?
Also do you think one might get a slightly smoother ride if you decrease the PSI in each tire slightly? I ask because I believe they are pretty high already at say 35 psi?

The wear rating on the 17" Potenzas was 400 - I don't know what the rating is on the Dunlop 19" tires. When my dealer wouldn't switch them out, I had them put on the tires from by G trade, which have a rating of 560 and had only 11,000 miles on them. They should last longer than the new RFTs. As far as decreasing the pressure in the tires, I wouldn't do it, for several reasons. A low pressure in a tire will make it heat up faster, and even if it didn't, the handling would not be the same. Also, remember that with colder weather coming, the pressure in the tire will go down even more. Even here in Tennessee, I have to add air to the tires in winter, in order to keep them at the proper pressure.
