My 370Z Feels wrong when making sharp turns
My 370Z feels so wrong (Jumpy and Tung, Tung, Tung Noise) when I make sharp turns, specially left ones. I took it to Nissan and they told me that It was a Z thing. 370Z with the 19" wheels tend to do that. This is my 4th Nissan and it sounded like bullsh!t to me.
Please feel free to comment on this, cause I cant believe that Nissan did this.:crying::crying::crying: |
It's most likely your tires are breaking loose. In cold weather, the stock Bridgestones tend to do this. It's not the car, it's the hardness of the tires in cold weather.
|
can you give any more description to what it is doing that feels wrong?
|
Have the dealership show you in a new Z if its supposed to be normal.

The dealer showed me with another used car and it did the same thing. I just bought this car and I freaked out about this sh!t. It pissed me off that I payed $32,000 for a car that does this sh!t

Dude are you sure it isnt the tires?? How fast are you going when you hear this noise??

Can someone help me find good all season tires that will not diminish performance
|
Continental DWS.
You're not going to find an all-season that won't diminish performance. As long as you're not trying to track the car at 150mph, then the slight reduction in performance will be negligible. Don't blame the car for the jumping, it's strictly the tires. If you put the same size tires on another car, the same thing will happen. It's just basic physics at work. |

What you need is a set of winter wheels and tires (especially if you need to drive around in the snow) and a nice set of summer wheels and summer tires for maximum warm weather performance. :tup: The summer tires on your car now get very hard in cold weather and skip across the surface of the road during tight corners or high load situations. That's the noise you're hearing and feeling. If you can't have a summer and winter set, and are going to rely on your car in the snow, then the Continentals TreeSemdy suggested are your best bet. They are the only all-seasons that have any real snow capability. |

is your car 6-speed? If you start the car and turn a sharp left/right out of a parking spot lets say and it makes that noise, I found its from not enough RPM's, it doesnt come from clutch or engine shutter but sounds/feels like wheels are jumping.. get the RPM's up higher to at least 1500 or more and try that, see if it works.

If you are making a sharp turn in cold weather with summer tires and it feels like the tires are skipping over the pavement... it's because they are. That's just how these compounds of rubber behave when they are below operating temperature. |
Ya it's just the tires, and it only does it when your going really slow. Mine does it when i back out of my drive way while cutting a sharp left turn. It's normal.

Okay, I will explain since people are still asking and wondering about rpm and all that jazz.
When you turn the wheel allllll the way, and you turn at low speed, the rim turns--and the tire turns. The rim turns at a set speed, and so does the tire. However, the inside of the tire is pivoting/turning in a tight radius, while the outside of the tire is describing an arc, and needs to be turning much faster, as it must move to cover more ground on the outside than must the inside....except it's on the same rim, and is the same diameter as the inside of the tire...so it's NOT turning much faster. It's turning at the same speed, axially. The problem becomes apparent with wide, sticky tires. The wider and stickier, the "worse" it becomes. The outside of the tire cannot physically perform this action, as it is physically attached to the inside of the tire as tires are a 1-piece affair, and they are both only able to rotate axially at the same speed, yet the outside of the tire is of equal diameter to the inside and MUST! cover more ground during the sharp maneuver. The inevitable happens. It "skips". This is what you hear and feel. The outside of the tire breaking/gaining traction to keep up with the inside of the tire. My Z06 does it, your 370Z does it, etc. etc. The solution is to: Create a vehicle with narrower tires (sucks). Create a vehicle with less articulation in the steering components and thus larger turn radius (sucks). Create a tire that is larger on the outside than the inside in diameter (WTF?). Not whine about a normal noise that is not indicative of anything being damaged (WIN!). Quote:

Got It. Im a new Z (1 week) owner and did not know this. Thank You all for your great comments. Ill go with Not whine about a normal noise that is not indicative of anything being damaged (WIN!). :driving:

If you've never driven on summer tires before, be sure to be very careful with them when it's really cold out. When you first start the car up in the morning when it gets really cold they can be pretty dangerous. Your stopping distance will increase tremendously (almost as if you're on ice) and emergency turning will be nearly impossible until the tires can warm up some. Usually it takes 10-15 minutes of regular driving before the tires are warmed up enough to where you're at really safe levels of grip for emergencies, but even then you need to be careful.

It was in the mid 20's when I left today. Still have the OE wheels with the RE050a summer tires. No skipping or binding coming out of the garage/driveway. Maybe this phenomenon is something that happens as the tread decreases.
Probably mount the snow wheels this weekend during this last warm spell (chicago). |

I always drive with this kind of thing in mind until I see a 3psi or so increase in the tires. Our TPMS shows us individual tire PSI and it is very useful as a rough diagnostic for when you can play a little. Oh...sharp turn in a parking-lot at wheel-lock the entire front end was shaking and vibrating and the car resonated with the phenomena OP mentioned. It's normal, even in supercars. *The girl at Nissan who is working with me told me the 370Z had a TPMS read-out for individual tires. I don't own it yet, so I have not fiddled with it, but I could NOT find it during the test-drive. I doubt it exists "normally", but is there a way to crack it? I know on the mustangs 99-04 you could get them to display engine RPM digitally, ACTUAL oil-pressure, and all that through the Info center on the dash if you followed a procedure. 370Z have anything like that? |

Import, only the 350 has the individual readouts. They killed it on the 370

WinterSports going back on this weekend. |

I havent found a reson why to buy winter tires yet and I dont want to spend 1 or 2 Gs on something I wont need. Im new here I was from FT Drum NY wich we meassure snow by feet not inches and I thought I needed winter tires in MD. I still dont know |

If you rely on your 370Z every day I think you should invest in a winter wheel/tire setup. You can build one on Tirerack.com that isn't too expensive. |
49* here right now. It was 40* when I left home, and the high is supposed to be like 70.

I get the same jump feeling on tight turns in cold weather. Usually when the tires warm up it goes away.
|
I get the same thing.. when the road is wet you can REALLY hear and feel it.
