Nissan is 4x114.3. If the rims have two-sets of 4 (8 holes total) then they will have a 4x100 AND 4x114.3 mounting capability. I would validate first.

Yes, percentage of width.

sure
KimberKenobi wrote:C) So then my tire sizes were 205/45-17, 205/50-17, and 215/45-17. 1) I chose 205/50-17 and found a set of Yokohama S.drive tires for $115 each. 2) As of no consequence is the fact that the 205/45-17 in the same tire is the same price. 3) I definitely don't want to go to the 215 size... 4) I'm not sure if the 50's would fit on the Camel because I have no idea what the overall size of this would be... it makes my brain hurt. 5) okay, I sat down and thought this through... stock tires = 185/65 which equals ~7"/4.5" (thus overall size of 15"+9" = 24")205/50 equals 8"/4" (thus overall size of 17"+8" = 25") which is what I want - an increase of the overall size of the tire. OMG, is this right?!?
Stock tire =4.5" sidewall, 12.2" radius, 24.5" diameter, 76.9" circumfrence, 824 revolutions a mile.
with 205/50-17 =4" sidewall, 12.5" radius, 25.1" diameter, 78.8" circumfrence, 804 revolutions a mile.
So, with the 205/50-17 your speedometer will be 1.5mph slow at 60. Now, if you go for the 205/45-17 tire, your speedometer will be .5mph fast at 60mph.

See above. Both options are relatively minor

Depends on the package you get. Again, you are only looking at a maximum of a 2.5% difference.
KimberKenobi wrote:C) Would/how would this affect my fuel economy?
Yes, assuming the new wheel/tire package is heavier you will get worse economy

Here's a article I wrote for the Maxima guys but it should explain it for yahttp://
