I would like to here from other Altima/Nissan owners. Are you experiencing any vibration/ride harshness with the following tire:

Continental P215/60R16 94T Touring Contact AS

Thanks.

I have the 2005 3.5SE sport with Bridgestone tires. Ever since day 1 I have experienced miled vibration at speeds over 70 to 75.

I have vibration and noise all the time. Also, the inside edges of all the tires are wearing/cupping. Nissan says it is the tires, General says it is the car. No one will fix it. So here we stand, it is no ones fault but my own for buying the car! It is going back to the dealer again tomorrow for the same problem. The tires are shot at 21,000 miles. It feels like the tires are not round when you drive it..

I own the 2005 Altima which came with the Continental Tires. I found out, belatedly, that I was to rotate the tires every 7000 miles. Well, I didn't realize it until I had put on some 16,000 Miles. After the first rotation I notice the loud humming noise similar to what you have described. I took the car to a Discount Tire store and the folks there said it was a "feathering" problem. The dealer confirmed this and said there was nothing I could do about it. After 31,000 miles, I had had enough and had some Michelin Radial X tires put on. Oh, what a difference! It is smoothe and quiet now.
I read in a car magazine about Nissan's problem with "feathering" on their 350Z cars. I called Nissan today and asked if the warranty or replacement reimbursement applied to the Altima as well. They said no. They were not aware of any recalls concerning the Continental Tires. I logged a complaint. If you want to call them, here is the number - 1-800-343-0294.
If there is a continuing pattern of complaints, we may have a case.
I still like my Altima, regardless.
Best wishes.

I have a 2005 3.5 SE with Bridgestone tires and have the same problem along with numerous other problems. They had to replace the rear sway bar because it would not stay in place and the vibration is still there now they are telling me that it is the tires. They won't replace the tires all they will do is force spin the tires which is a waste of time. The car is in the shop where it stays more than I get to drive it, I am having electrical problems along with all of the vibrations that they can't get out of the car. The car also will not stay in alignment.
Good luck on getting Nissan to do anything. I hate the car that I once loved!

i own a 2005 Altima 2.5S, it came with the continental Touring AS tires. they were loud, and very poor in rain. I developed a vibration at 20,000 miles that no one even the dealer knew the problem. I replaced the tires with B-stone potenza's 216 60R 16's and the vibration, noise and poor rain performance are gone. The continental tires are very poor, replace them for the rain safty alone, i would not let my wife drive the car ever in the rain with those tires.

Just to keep all of you updated. My car was in the shop again two weeks ago for tire problems with feathering (chewed up/cupped) vibration and noise AGAIN! After less than 4000 miles since the last alignment, the dealer says the toe was already out again. I am talking normal driving on city streets, not off-roading. They realigned it for free but, I am afraid this will be an on going problem with this car. The dealer says they cannot replace the Continental tires unless Nissan North America says they can. They will not, as Nissan North America says they do not warrant the tires. I was going to bite the bullet and replace the tires myself but, if the car will not stay aligned, I will just be wasting more moneyon it.

These links refer to the front airdam causing vibration at higher speeds or windy turbulance. http://www.nissanclub.com/forums/showthread.php?t=188530&page=12&pp=15

You will find twelve pages of info on the first sight. Pics on the second.
I give this same info to my dealer and they have offered to modify (remove)
the airdam(2006 3.5sl) on their own dime. Nissan USA admits no problem, yet the SE-R (racey model) has no airdam.

One test I found interesting was finding a windblock (semi) at higher speed and see if vibrations are reduced.

Good Luck

Wow, I just read about problems other Altima owners were having with the tires. So I checked my tires and they are Continental Touring AS tires, mine are feathering and cupped. I drive very little and was chastised by the dealer for not having them rotated soon enough. I rotated them at about 12,000 miles front to back. I realize that the front wheel drive can eat up a tire but they are close to replacement time. At about 16,000 now I have to look forward to just wearing them out. I guess I will join the list of unhappy Continental tire users on the Altima. thanks

i have to admit the continentals are crappy tires. although you do need to rotate the tires every 6,000 miles. i rotate the tires on my truck every oil change, or 3,000 miles. i know it kinda sucks but i would go with either bf goodrich or michelin tires when replacing them.
