I cant tell you how much I hate how the runflats handle in the cold weather. I wish I could drive a Q50 without runflats to see the difference.

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.

Anybody looking for a set of 17" runflats
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.

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.

The RFT's have a treadwear of 260 which is better than the RE050 the M37s had. Those lasted me about 32000 miles so im hoping to get 40k out of the Dunlops.

I love mine...I don't have any issues with RFTs. It's much quieter than my prior G37S and my last M37S.

I didnt want to say it earlier, but i feel 100% the same way in comparison to my previous G37s and M37s as well. Glad I know I aint going crazy
