The OEM Contintial 205/65/16's that came on my Altima have a couple of thousand miles left on them. They haven't rode that good after 15,000 to 20,000 miles and they only have less than 30,000 on them. I want to so with 205 to 225 60 or 65's. What brand and size has anyone used that they like. Has anyone put Yokohama's on a Altima yet.?
I cannot seem to find the recommended tire pressure for my '05 Altima 3.5 SE. I looked in the manual and it tells you to find the sticker on the driver's-side centre (B) pillar. No dice... the sticker there tells me all sorts of things (VIN, mfg. date, colour code, engine type, etc.) but not tire pressure. And yeah, I have checked all the other door jams to no avail...
In my '02, it's on the underside of the center console lid.

I looked a few weeks ago and you're right, it's under the lid of the main armrest storage bin (not the shallow top one) on my 2005 Altima. I think perhaps Nissan should update its owner's manual to tell people where it actually is.. still says it's on the driver's-side "B" pilllar in mine.
The car is wearing Bridgestone Turanza P225/55R17 rubbers and they're all currently around 30psi, but I don't know if this is right or not...
I had encountered the same problem several months ago, but I was able to locate the information over a website that shows recommended pressure for different tires for specific car makes and models. If I remember correctly , the recommended pressure was 30/32 psi for rear/front tires. The recommended pressure vary from summer to winter by 2 psi. I was driving around with 36 psi, considering that a safe tire pressure Vs maximum pressure of 40 or 44 psi that the tire was rated for. But the ride felt wobbly and I realized that the dealer was right when he warned me that I have set the pressure too high.
I've noticed a lot of people asking questions on here about tire sizing who obviously don't understand what they mean. So, I thought I'd be a good forum denizen and put my knowledge and writing skills to work.
Tire Sizing Decoded
For this example I'm going to use a tire sized as follows: P245/45ZR18
P = Passenger Car tire (whereas LT is for light trucks like pickups and SUVs)
245 - tread width in millimetres. In other words, the width of the tire where it contacts the road.
45 = aspect ratio of tire's sidewall to width (as a percentage). So, in this example, the sidewall would be 245mm x .45 = 110.25mm.
Z - speed rating (i.e. how fast the tire is rated to go). A 'Z' rating happens to be the highest for passenger cars, able to travel at 186mps (300 km/h). However, most passenger cars make due with far less capable tires (what normal car can go that fast anyway?)
R - radial. This harkens from before radials were the norm, back in the days of the infamous bias-ply tires (before my time though).
18 - wheel/rim size in inches. Enough said.
Calculating Tire Diameter
This following may seem a bit complex to some, which is why I've also included a link to a javascript calculator made for this purpose.
Tire Diameter (mm) = (((tread width x aspect ratio) x 2) + (wheel size x 25))
Note: The above formula assumes all values are in their original formats (i.e. mm or inches). To convert millimetres back into inches just divide by 25.
Since the circumference of a tire is directly proportionate to its diameter (you do remember grade 5 math don't you?), the one will change with the other.
The speedometer (and odometer/trip-meter) in a car are calibrated based on the size of tire the car came with. If you put on a tire that is bigger or smaller than the original, your speedometer will no longer be accurate (although most aren't too accurate anyway - Car & Driver did a test on that a few years back - if I recall correctly, japs were most accurate, euros were least accurate, and domestics were somewhere in the middle).
If you put a larger tire on your car, it will take less revolutions of that tire (versus the orginal smaller tire) to move a given distance. Thus, your speedometer will tell you you're going slower than you really are, making it likely you'll encounter the local constabulary sooner or later.. not a good thing. Putting on a smaller tire will have the opposite effect, making your speedometer show you're travelling faster than you really are... at least you can't get a ticket for that.
As well, the ECUs in some newer cars don't like it when the tire size is changed, and will throw a big hairy fit as a result. So, in short, it's best to keep the diameter of your tires the same as orginal equipment.
What is a Plus-1?
This is basically used to describe the act of increasing the size car's wheels/rims by one-inch while keeping the overall diameter of the tires fairly constant. As a rule of thumb, this is done by increasing the tread width by 10mm (i.e. 255 instead of 245) and decreasing the aspect ratio by 10% (i.e. 35 instead of 45), and increasing the wheel/rim size by one inch. It's quite difficult to get the diameters to match exactly, so generally you just have to make due with the closest match.
Hopefully this information has been useful to you. I'm sure other forum members will insert their valuable information after, so go read that too...
Blitz, I have a 2003 Altima, and I had put 19's on it, but the rain in San Francisco put a million pot holes out there and as a result my rims got tore up, I went back to the originals until I get some new ones. My question is how much meat can I put on my tires if I get 19's again, and how much meat for 18's..... this is where I am thinking that this might be a better bet to help me deal with the pot holes that will pop up from time to time.....and when say meat I mean the width from the tire to the rim as I drive down the road. Thanks for the Advice.

you want to try to keep the same diameter as the stock tires which is 26.3". You can go alittle taller, but not taller then 27". I currently have 245/40/19 which are 26.7" that's a sidewall height of 3.9".

Let me try to explain OFF SET. Take a rim 7"wide. The center if the rim would be Zero, no OFF SET. That means you have 3.5" of rim on each side of the center. If you move the mounting hub of the rim outward away from center that would be (+). If you moved the hub inward that would be (-). So moving the hub +42mm of the rim outward from center which is about 1 5/8" you now have 1 7/8" on the outer side of center and 5 1/8" on the inward side of center.
From my own measuring I figure you can safely go 5 3/4" of inset from center on the 3rd gen Altima. You could go 6" depending on the tire size.
have 93 altima with p205/60/r15 tires. Very difficult to come by at decent prices. Plz recommend change to a more common size that will not affect overall performance. Thanks a bunch for the info.
Hi I am a newbie to Nissan Forums. I was wondering if I could put some 20" Davin SS2 on my Altima? I am a newbie and I was having trouble finding information about this.
