Reccomended Tire Widths for Stock Rims
Hey all.
I've got a 2006 Nissan 350 Touring and have decided to replace all four tires after my back OEM tire blew out with Goodyear Eagle F1s and figured I might as well play with the tire widths etc while I was at it. I know very little about cars and was hoping someone could recommend some combinations that will fit on the OEM rims which I am not replacing and say what the pros and cons are of various combinations. For example, will changing the widths somehow change the accuracy of my odometer etc? I would think this is only true with wheels of different diamter...
Also, I've heard talk about no-touch tire mounting or something like that? Is this a really such a big deal that I should be sure to find a place that mounts this way?
Lastly, after I put my new tires on I'm going to have 3 perfectly good oem tires with about 500 miles on them. Is there somewhere to sell things like this? Can I do anything with them because throwing them out seems like a shame but I don't really have anywhere to put them.
Much Thanks.

I know very little about cars.......... assume better traction since wider wheels?
The contact patch AREA always stays the same regardless of width......pure function of weight on tires and inflation pressure. The shape does change, however----wider just narrower lengthwise.
Lower sidewall height just changes the sidewall stiffness.
Traction [dry] is a function of tread softness the faster the tires wear the better the traction between the road surface molecules and the rubber molecules.
Wider is not always better especially when friction drops due to temperature or moisture.

Ok. So then can someone explain to me the point of having wider wheels? Is it that it looks better? The lower profile 245/40 and 255/40 wont make the car look weird by making the space at the wheels larger since I haven't lowered my car will it? I've heard that it's pretty large and open to begin w/...

The tires that came on my 05 touring were 225/45/18 and 245/45/18 ... I wouldn't get much wider tires unless you have much wider wheels.

Wired: Thanks for the info.
Any opinions on whether the 245/40 front 255/40 back on OEM rims will make my Z look weird since I haven't lowered it or done any mods to it at all?
Appreciate it.

As Q45tech and Wired 24/7 mentioned, the outside tires hold the car to the pavement. If you can keep more rubber on the road, the better. BTW 295mm of crummy rubber is no better than 235mm of quality rubber. And adding 10, 20 or 30mm will not turn a novice into a pro.

8" wide wheel... 225 minimum - 245 maximum
8.5" wide wheel.... 235 minimum - 255 maximum
9" wide wheel... 245 minimum - 265 maximum
9.5" wide wheel... 255 mimimum - 275 maximum
10" wide wheel... 265 minimum - 285 maximum
10.5" wide wheel... 275 minimum - 295 maximum
11" wide wheel... 285 minimum - 305 maximum
Front - 245/40/18
Rear - 255/45/18 or 265/40/18
- Any bigger the side wall will bulge and lower lateral performace, also the tire bead will not seat properly and cuasse blow out.

Your speedomoter is reading 2.2% higher than you are actually traveling.
So when your speedo says... "80mph" it is really... 78.24mph. so for every 100 miles, you are actually putting 102.2miles on the car, b/c your 236/40 size is smaller than your stock size, even though the width is wider. That's an extra 330miles for every 15,000 miles of driving.
I know; lame... but true.
A 245/40/18 on the front reads 1% too fast, and would add an extra mile for every hundred miles; an extra 150miles for every 15thousand miles.
REAR:
You rear is reading 2.4% too fast. A 265/40/18 would read 1.3% too fast.
So the propper PLUS size on stock rims are...
245/40/18 front
265/40/18 rear
Anything bigger thatn these previously mentioned sizes will push the side wall over the rim, and cause the tire bead to not seat propperly, and drastically reduce lateral handling; aka... BULDGing.

A new question for you. Since it's the VDC/TCS/ABS system that sends the speed signal, which wheel is the one actually read? Or is it an average of all four?
Also, not all tires of a given size are really the same size.
And finally, the odometer correction on my car is the least of my worries. All the beter if I'm travel slower than my indicated speed. Less speeding tickets. I'm much more interrested in the car's balance and performance.
