lol... I don't even know how much sawblades weigh w/ tires... Around 35-40 would seem about right.. since I just carried them around yesterday.
Heh... even if you figure out what the tires weigh... and subtract that from the approximate weight of the new tires and wheels... what do you do then? How much speed / accel does a 5 lb wheel reduction make?
You can calc until you are blue in the face, but the end result is going to be the same - put 'em on and try it out. If it's too much, turn up the boost.

Grim is right, your dealing with many variables here.
Weight is one.
Diameter of that weight is another.
Total rolling diameter of the finished wheel/tire combo is yet again another.
I'm running SSR Comp's in Anthracite, they are about 16lbs each for the wheel, and Goodyear Eagle F1 GSD3 tires, 255 front, 285 rear in 18's to clear the brakes...
These were totally lighter than the 17" MK4 TT rims and Kumho tires I had on there before, which were totally heavy compared to the sawblades and 225/50's. (Used to run 255 front, 275 rear in 17's.)
Now that I've added the brakes, the unsprung weight is back up slightly, and so it the rotating mass, but it's mass that I'm willing to haul around as this car needs the better brakes to slow down.
So, to answer your question, it's going to depend on what you were running, sounds like sawblades, and what your willing to pay for the 18's. If you buy cast wheels that are 30lbs each, and add in the larger tires, your going to have a heavy wheel that looks good, but hurts your performance. (As I did with the MK4 wheels.)
Or spend the money one time, and buy the rims forged and light, and with room for larger brakes, because you know you want them sooner or later. LOL
Good luck.
