Are the 19" Dunlops supposed to be better than the crappy 17 Bridgestones? Is anyone planning on trading their tires in anywhere right after they pick it up?

Good question. I never even thought that trading out tires was an option. I'd love to know if it is.

I've been a Michelin fan for a number of years. I hope they have a decent model that would work well with this car.

Just saw a recommendation for a Michelin tire in another thread. I'll have to check that out.

I traded tires the same day I got my Acura TL because everyone was saying how horrible the stock tires were. I drove it straight to a discount tires and they gave me an $80 credit per tire.

My Tire shop said that they will give me $200 credit per tire for the 19" Dunlops.
This is if I pay the list price one the Michelin.

If you lease, just store the oem tires and put them on say 9 months before the lease return.

Sooo question!! Would it make a difference in tire/brake performance if I bought a Premium with 17" tires and traded in the tires for "regular"/better 17" or are the 19" tires better in general?

I don't think you have to return it with run flats. I've turned in many leases with different tires, sometimes MUCH cheaper tires because there was only 9 months to go, and no one has ever said anything. They just look at the tread life.

I don't think so either. I just had my lease inspection done a couple of hours ago and there wasn't any issue with my tires that are not run flat tires.

The bottom line: Despite the disadvantages and inconveniences of run-flat tires for many, IMO that the safety benefits can outweigh the downsides. And the technology behind them is improving while prices are coming down.

How much are the Michelins?

It depends on who inspects your car. They suppose to look at wear, correct size and speed rating. The G37 never had run flat tires.
Most BMW owners had problems when they tried to return a leased car with non run flat tires.

The 17s will be cheeper and have better ride, the 19s will look better and probably have more dry grip (are you planning to autocross your car:D).

The best dry performance tire in 225/55/17 is:

Micheline Pilot Super Sport is by far the best tire in 245/40/19 size:

I don't think the 17s felt any better on the Q

And if it doesn't say in the lease that the tires have to be identical then they can't hold you to that

Probably something more distinguishable on rough roads! I can definitely feel the difference of my 20s and 19s and am thinking the 2" difference would be significant but then again the run-flat tires might be a factor as well!

Corrent lease terms call for same speed ratings for replacement tires. They will
probably update it to include run flats (this is the first Infiniti to use them).
BMW specifically states that RFTs must be used as a replacement.
