I have a 180 or a 190 rear tire. I forget at the moment. My buddy is looking to off load his rear tire which is pretty new however it is one size smaller than mine. What will i expect if i put this tire on the back of my bike. Or should i even bother? (Ive got an 05 640 Adventure)

Check the sidewall of your tire size as I'm positive you don't have a 180 or 190. The largest rear dualsport size I know of is on the big duallies which will be a 150. Big sport bikes have 180 or 190 rears. You probably have a 130 or 140.
The tire size looks something like this:
150/70-R17 73Z
The 150 is the width in mm
The 70 is the profile in percent of width in this case 70% of 150mm or 105mm tall in this case.
If there is an "R" next the tire uses radial construction otherwise it's bias-ply.
The next number is the rim diameter in inches.
The load rating is next, "73" in this case means the tire can carry 805Lbs at max inflation pressure.
The next letter is speed rating i.e. Z is 240KPH, H=210KPH, S=180KPH etc.
I have an HP2 that calls for a "140" rear but that size is not always brought into Canada in the tire I want so I have run a "130" at times. You won't run into clearance problems running one size smaller tires, but you might have load rating issues.

if the tire width is wider for the recommended rim width: riding becomes wobbly, the sidewall of tire deals with more friction, good for riding on rock with low pressure,...
If the tire width is smaller for the recommended rim width: the ride becomes stiffer, rocks end up between rim and sidewall of the tire, rim damage,...
there is probably more to it when i know.
however, this is my experience
