First, the bolt pattern is 5x114.3 (some places may call it 5x114, dont get nervous)
Lug Nut size is 12 x 1.25 (make sure to pick up a thin wall socket)
Something that is very important is staying close to the stock diameter of the entire tire/wheel combination.
Check this site out.
http://www.miata.net/garage/tirecalc.html Once you find the wheel you like, use that to find the right tire size.
3.5 Stock Information 17x7.5 26.3" Diameter +45 offset ---> 215 / 55/ 17. This means, the tire is 215mm wide, the side wall is 55% of the width of the tire (215 x .55 = 11.825cm) ... 11.825cm / 2.54cm per inch = 4.655 inches for each side wall. 4.655 x 2 (two sidewalls)= 9.31 inches + 17 inches (size of wheel) is 26.31 inches. (incase you wanted the math)
So for a 20" rim, you could get a 225, 235, 245, or 255 cm wide tire, however, note that when you go wider with the tire, the smaller the sidewall is gonna be in order to fit close to factory specs. And the smaller the sidewall, the more uncomfortable the ride will be.
For 20" rims, here are some possible tires to stay close to factory specs
225/30/20 = 25.31225/35/20 = 26.2225/40/20 = 27.08
235/30/20 = 25.55235/35/20 = 26.47235/40/20 = 27.4
245/30/20 = 25.78245/35/20 = 26.75245/40/20 = 27.71
The ones in bold are the closest to factory specs. You can do the same equation above for 18 and 19" rims
Some specs on 19s19x8:225/40/19 = 26.1"235/40/19 = 26.4"
19x8.5:235/40/19 = 26.4"
And some on 18s18x8 on 235/45/18 will get you to EXACT factory specs (26.3") but 225/45/18 (26.0") is damn close enough and tires are a lot cheaper.
This info is for the 08 Altima Coupe and is a work in progress... Chime in with your fitment/offset/drop
ALL Stock Infiniti G wheels will fit.
Ovrbst had NO RUBS with a staggered 19x9x5 fronts and 19x10.5 rear setup (no drop, that would cause issues)
I will be "sweeping up" the thread to make it very easy to understand.
