1. anyone with 20's have any problems with rubbing?
Depends on offset and overall diameter. IF the overall diameter is the same as stock of VERY close, there shouldn't be problems there. Now, offset and width could be an issue, but I don't know the xB characteristics enough to say.

2. what kind of life span do the tires have?
Which tires? The Falken FK-452?
That same page CLAIMS: "High Performance 40,000 Mile Tires rated 300/AA/A"
So, IF they fit on an xB2, they should get a decent lifespan.
BUT, I'd try to keep close to overall stock diameter (so, the speedometer and ODOMETER remain close to accurate.

I'm running 225/50/16s, which are only 1.5mm CIRCUM. off from the stock 205/55/15s while being 2cm wider. No rubbing issues.
Use THIS chart:
http://newscionxb.com/wheels_tires/eddnogs_xb_20_wheel_tire_chart-t23.0.html
Try to keep it in the GREENS to YELLOWS, which leaves these for 20s:
215/30/20 (yellow) +16mm circum. from stock, +.48 MPH off
235/25/20 (yellow) -20mm cirum. from stock, -.61 MPH off

Those are both close enough to the 2-5 width that a 40 offset works, as would a 30 (work=no rubbing).

As for the Falkens . . . they only list: 245/35/ZR20 and 255/35/ZR20
BOTH of those would be MUCH larger diameter AND width than stock, so rubbing is a HUGE probability, while Speedo and Odometer would be WAY off too.

3. do they affect MPH or MPG in any way?
MPH-> see above. Yes, it will. IF you use one of those 2 tire sizes, it could be "ok" otherwise, A LOT.
MPG-> depends on rolling (overall weight). Lighter is more efficient (everything else equal). 20s TEND to be notably more heavy than the stock steelie combo (43-44 pounds overall). More weight takes more HP to get rolling and also more brake energy to stop it rolling (inertia issues), plus it takes the steering system more work to change direction (steering-> same reason).
Most who run 19s or 20s seem to think that the look more than offsets the cost.

4. are these wheels nice or what? :naughty:
Quite pretty.

I wonder what they weigh . . . ?

YESSER...

im rollin with 20s with 35 series tires.. i have not had any issues with rubbing.. had my whip since feb custom ordered that way, and already did the first 5 k maintenance and askede about the rims and tires and they told me it was ok.. if TOYO put them bad boys on there im sure they would have said something about the size..*thaz what she said* hahahah

anyhows.. i also had the car lowered about 4 inches and have not had issues with the rear tires either.

SHouldnt ahve problems.. as long as you dont go with a tire bigger then 35 series..
mine will do full turn with those.. no rubbing..

and those are sharp 5 stars.. id get them myself..

I've got 20's on mine. No problem. Since 4-08. The dealer put them on. I sort of wish I didn't have them, I'd like to lower the nugget. Husband likes them a lot. He agrees with lowering, but he says it would make the car not as smooth. My nugget is a daily driver, I don't do much speeding, sometime you don't know that you are. LOL.

Still . . .
I'd keep an eye on the weight.
That will affect more than most people realize. That said, they ARE combos that will work GREAT and still be close to stock weight . . .
I can't find anything giving weight of those . . . oh well.

ENJOY!
