Aside from the obvious what's the differance between a 15/205 50 or 17 with a tire that would give me the same circumfrance as the above mentioned tire? I don't want to change the stock tire circumfrance.

1 word: "construction".

both were constructed differently.

with the 17s, you'll be using 215/35/R17 tires (most likely), which usually available as "Z"rated tires. Z rated tires are known to have stiffer steel belts as the back bone of its sidewall construction, therefore giving you a rougher ride. But this in turn also helps stiffen up the suspension a bit, therefore giving you a bit better turning response. And depending by the manufacturer, and what the tire is intended for, the rubber/silica compounding is usually much softer than what's fitted on most grocery getter. More grip, at the stake of lesser tread life.
I think you might want to check with www.yokohamatire.com for further info on tire's construction, here: http://www.yokohamatire.com/csunderstand.asp

not that I want to start an argument, but please read the first post, he said 205/50/15, not 205/60/15.

By then the tire's aspect ratio is already lower by 10 from what is stock (205/60/15)

I have a set of 205/60 15 I want to replace the stock steelies with an aluminum 15. However I would like to go a little wider in the future without compromising ride quality so I thought ?/50 15. The car has been dropped so wheel well spacing is not a consideration. The consensus seems to be to go with a package deal on 17s. But I want to stay 15 and keep the ride quality and safety. This may be a cruise missle but it also doubles as a family car so safety is of the utmost importance. PEACE:p

eltiburon8u, I'm guessing that you don't have a full understanding of plus sizing and tire dimensions. Here's a few things you should look at and play with...

http://www.tirerack.com/tires/tiretech/general/sidewall.htm

http://www.tirerack.com/wheels/tech/wheeltech.htm

And here's listing of tire/rim combos that will fit on the Altima without throwing the speedo off...

Stock: 195-65-15, 205-60-15
Plus Size 1: 205-55-16, 225-50-16
Plus Size 2: 215-45-17, 225-45-17
Plus Szie 3: 215-40-18

And you shouldn't be afraid of going with bigger rims and a smaller sidewall. Low profile tires have much stiffer sidewall to make up in the loss of sidewall height, just like lowering springs are stiffer to make up for the loss of suspension travel.

I'm riding on 215-45-17's and hot numerous potholes, and I'm still good.
