I pulled out of the garage this morning, before doing the detailing, so I could program the Homelink, which thankfully, went well. I then turned the car around and backed into the garage, using the around view monitor. It took a couple of tries to get it straight in, and while I was maneuvering the car, I heard the most outrageous sounds - I thought I was scratching the car against something - I'm sure you can guess what my emotion was at first. I then realized it was the tires putting out that scratching sound when I was turning the wheel. I have never heard anything like it from tires. Monday, they go!

The tires are pretty bad.

wow, that's pretty critical. lots of reasons to change tires, but this is a new one for me :)

Just like everyone else here, I'm convinced that the RFTs are terrible. I took a short drive today, and the tires are LOUD. Worse that that, they accentuate every bump, something I never noticed before with my G. It's possible that the bumps were harsher because the hybrid has the sport suspension, but I doubt it. Monday will tell.

I understand. Not a huge fan of the run flats, have just never considered dropping a tire because of the screech on garage concrete :). I see that you were changing them out anyways and this was just another reason.

You're right, it is just one more thing. Even without what I heard in the garage, there's no way I'd want to live with the harshness of the ride. The loudness on the road would be annoying, but if that were the only thing, I'd probably keep the RFTs.

I'm going to change them out because I know they won't last the lease anyway, so why put good tires on with a year left, when I can put them on now and enjoy them the whole time. Then I can put these back on just in case Infiniti really does expect the leases to be returned with rft's. I'm putting Micheline AS3's on in a few months.

I have run flats on my GT-R and they are noisy. I don't think the Q50 run flats are that bad at all. My .$02.
I agree that I don't think the Dunlop RFT's are noisy, but they are extremely harsh riding and bone jarring over bumps. Their grip could be better too, a test that has come more to light from many professional reviewers.

My S04's are soft and quiet and grip like crazy glue, so it was worth it just for that.

I'm no expert on RFTs, having just had the car for one day. I also don't know about Dunlops. However, the Potenzas that are on my Premium Hybrid made riding very uncomfortable. It felt like the car had no shock absorbers. I assume that on a smooth surface, they would be O.K., but most side streets aren't smooth. I also am guessing that you'd feel every joint on a highway. If, after putting the Yokohamas back on, the car feels the same way, then I'll admit it's the suspension. I just don't think it will come to that.

It isn't just the brand but the specific tire. I took the RFT's off and I had the Potenza GForce Comp2 put on, they rode good but very noisy, so I changed them out for the S04's. Every tire even from the same manufacturer is different. The Potenza S04's are great and not in the least bit uncomfortable and I have the Sport. I highly doubt it's your suspension but you might want to have it checked at the dealer anyway just to be sure.

Wow, what a difference!

I came back from the dealer with my "old" Yokohama tires now on the car. Unbelievable difference in ride quality. That just confirms that it was the tires that made it feel like I had no shock absorbers. It is well worth it to get rid of the RFTs!

So glad to hear that getting rid of the RFTs solved the ride issues. That gives me more confidence about buying one. One question, with the Hybrid, what do you do if you get a flat, particularly if you're out in the boonies?

Well, that is the only issue if it does happen, but I'm sure roadside assistance will be able to find you, just pack some food and water and a book if you're traveling through the boonies.

I had a E46 M3's and they never came with a spare either, luckily in all the years I had it I never had a flat nor worried about it.

I bought a Craftsman tire inflator package at Sears, which I'm keeping in my trunk - it's small, and takes up almost no room. They have several different varieties. Mine was about $55. It "plugs" into a power outlet in the center armrest(or into the cigarette lighter in other cars). Well worth it.

I really wish I had the space (e.g. Garage) to store a full set of tires. That's my only problem at this point of swapping out the RFTs when I get my car. I live in a downtown condo now & have no place here to keep them. Wouldn't be an issue if I was back home in Big Windy. Maybe I'll run a cost analysis to see if it's worth it to invest in a storage unit. :(

After a couple of the days with the RFTs on the Q50 I agree with you. The car does have a stiffer ride than my G had but I thought the G was a little soft anyway. I like the ride.

These RFTs have been like a needle constantly nagging in my head every time I get behind the steering wheel in my new Q50S. I've never driven a car with RFTs before, so I figured I'd give it a fair shot at satisfying my driving needs. Well, I can only echo what others here have asserted; the ride is stiffer than necessary & can clearly be attributed to the tires, esp. in absorbing road harshness. I also searched online & couldn't believe my eyes when I saw the replacement cost is $460/PER TIRE. Added to the fact that they don't last very long, it makes no sense to keep with these tires when inevitably I'm going to have to replace them--relatively soon with my driving. Irritates me that Infiniti did not offer the Spare Tire package w/ standard tires. Anyway, I'm now in the market for a new set of tires; it sounds like Michelin Pilot Sport A/S 3 the way to go. I did a quick search & saw $250/tire. Is this a good price? Expensive but I never go cheap with tires; I just want the best deal.
