Tire noise from the cold weather
 

:confused:Anybody notice a stuttering or grinding feeling when turning the car slowly at either the full right or left position?

I get it as well, but initially as if it's TCS test kicking in.

I'll back out of the parking lot, turn the steering wheel, apply gas, and hear and feel the racketing noise from the front wheels.

I actually think with the wide contact patch in front, camber and toe angles, combined with "biting" tires, this should be expected. Mine does it too without electronannies having anything to do with it. I usually notice it more when one tires have two different surface types under them. Watch when you have a little dusting of snow... Then you really notice it. My judgement= completely normal.

i have just noticed this, one week ago. Its a very hard right turn while moving slowly.

My theory was, the tires turn so far to the right that the car is literarly pushing forward and the tire on the front are probably sideways so it makes a rubber skipping on the pavement. Hope that made sense

You should never turn the steering to full lock (where you should hear a noise). Unless you enjoy replacing your power steering pump components frequently.

Exactly correct........:iagree:

Yay! I've been supported by THE Modshack!

I've never heard of that?

I also have this tire scrubbing. It happens in both directions if you are turning tight going slow. Sounds like the front tires are scrubbing a little bit on the pavement. It kind of reminds me when you have your truck in 4WD and turn tight on drive pavement and you here that tire scrubbing. I have been meaning to go to the dealership and ask about this but haven't had time. Makes me fell a little better knowing I am not the only one having this problem. Is this normal for the Z with 19" tires?

It's not a problem...It is perfectly normal. You should hear the Corvette guys whine about this as it is worse on that car.

i too get tire scrubbing at tight turns, but i always thought that was from the rear wheels because of the lsd?

There needs to be a TSB for this.




j/k. :)

Perfectly normal. Happens a lot when I park at work.

BTW, my brother's Jeep SRT8 and parent's Supercharged Rovers do the same thing with their wide tires. My last FX35 did the same once I wore off some of the tread. I'm sure my new one will too. A little more grip, a little more scrub. Awesome!

m4a1Mustang, that's an awful color you picked. I wouldn't buy that in a second! Oh wait! JK...

Oh blow off! You Solid Red bastards really get on my nerves! :tiphat:

It is definately just the tires, and should only feel it in the cold temperatures. I have recently had it come back, now that it is starting to get cold up here. Essentially the tire tread rubber gets stiff in the cold weather, less flexible and scraps, giving you that feeling. Not a real problem, and may happen in warmer temperatures, but the rubber is probably more flexible and it doesn't scrap making the noise/feeling. Now, in my opinion it is a poor design (being a former tire designer), and shouldn't be on the car - they obviously didn't do much winter testing. I won't complain, not worth the hassle, since it only happens when the temperatures are low, and the tire is cold. It doesn dissappoint me every morning as I leave my driveway and have the issue occur. Just means I look forward to my first set of replacement tires.

Tire noise from the cold weather
 

another bug....

noticed last night that at full lock (not sitting against the stop, to the stop, and back off a slight amount) that the front end binds somewhere....

it feels like my 4x4 dune buggy with a lock front end.... or simliar to over extending a cv joing. you can feel it through the wheel and floor, almost like the outside tire is skipping. i find this very odd since my car is lowered about 1", nothing crazy.

now, its not that its a huge bother, but i am very anal and do not like "not knowing" what it is. nothing is rubbing i can visually see, and unfortunately no not have the ability to see under the car with the front weighted down (lift ect) to peek around.


also, ive noticed a clunk in the rear end.

here is what it is :ugh2:

Your rear sway bar is moving side to side. Check your bushings, they should be fairly-snug against the stop.

Mine scrubs near lock and it's at stock height. It was kind of a surprise, but the way I see it, I am willing to live with some scrubbing for the (great) turning radius.

I've done some suspension design and it is basically a huge pile of tradeoffs. I figure they needed to sacrifice correct turn toe for some other handling characteristic, but maybe I'm just being naive.

Mine does something weird whenever I have it a full lock and Im turning slowly (like coming out of my spot) but Im pretty sure it did it when I had the stock suspension on there too...

Tire Dragging on Sharp Turns U-Turns
 

A few weeks ago I noticed that when making a sharp turn (with the steering wheel turned all the way in either direction) you can hear a tire or two dragging on the ground. I figure that it's a result of the 370z having such a tight turning radius. I brought it to the dealership and they said it was normal, but has anyone else experienced this?

Are you holding the steering wheel at full lock? If so, it might be the pump making noise, not the tires. If you are, don't. It is very bad for the pump.

:iagree: turn off the VDC and steer with the rear wheels:roflpuke2:

Sounds like the LSD, if you have one (ie sport package). Have you modified the differential (new internals, new oil, etc.)? I have a 350 so not sure if 370 stock diff will drag the inside on tight turns. Perhaps understeer if you are carrying too much speed. ^+1 don't use full lock when turning.

In cold weather, the front wheels/chassis will flex and skip on sharp turns at slow speeds.

I read about it here, then a couple nights later I experienced it. Had I not read about it here, I'd have thought "WTF!"

i've had this same thing happen.. not until it got cold out though.
if i'm stopped and have the wheel turned nearly all the way in either direction and give the car a little too much gas i get the dragging feel in the wheel an the sound. feels/sounds more like the front wheels than the rear.

:iagree:

I also started to experience this tire dragging almost like the front tires are losing traction when the weather turned cold but once the car has moved like 150 feet it stops. I think its just the cold..

Only happened to me when it was cold outside. After a very short distance, it goes away. Whatever it is. :ugh2:

It's called crappy tires.

Not this again.

Ditto... after getting new tires with my wheels, I've not encountered this issue. :-)

Yes I do have a sport package with a LSD. But I think it's the front tires, not the rear. I could be mistaken though. Maybe I'll get someone to watch from outside.

I agree that it seems to only happen when it's cold outside, as I do not remember this from summer time. And I usually experience it when pulling out of my drive way to go to work in the morning when it's like below 40 degrees outside.

I also agree about the tires. This could definitely be the source of the problem. They suck in cold weather. I spin out too easily now in 1st gear.

Haha, nice. :tup:

They suck in cold weather because they are summer tires. If they are below operating temperature they are going to be slippery as hell... they are like hockey pucks in the winter. So if you insist on driving hard with them, be careful.

i can verify this it happened on my car everytime i took a slow turn near lock and caused massive understeer when i tried to make a yellow once(i know for shame but no one was at the intersection so i said what the hell). I'm wondering if the front tires are doing it merely due to the awesome width on the things just like how the car dances on the highway because it can't drop into the groove.

Yeah the road-controlled steering forces you to pay pretty good attention most of the time, at least on some of the roads I drive on. I avoid certain lanes on my drive to work.

Mine does it but only when I first start it in the cold weather. I noticed it twice when pulling out of a parking space. On a warm day, doesn't happen.

OH YES ! I HATE that road controlled BS. I was thinking it was just me due to a couple reasons such as my front is taller than the rear(pretty close if not) due to bad tires sizing and the front tires being a larger diameter tire than the rear. Thought maybe that was the reason for that road shxt. So the real reason is what then ?

Also could it be the LSD causing this ? Because I don't have one and I haven't noticed this issue.

this is exactly what happens to me. im glad someone else is having this problem (just discovered this thread)

yeah i was gonna ask about this too. when i start my car and get out of my parking space i have to turn my wheel all the way to the right to back up and it starts to act weird like something is grinding.
