255/40/18 on 8.5" at ET38 does not need a spacer. however if the rim was 9.5" then it would because the inner rim lip will touch the strut.
Thank the lord for that. I can't spend one more day looking at tire+wheel posts, I want to put it behind me for years now.

regarding 704M weight, i could not locate it anywhere. however since 442M and 403M weights are known and the 704M is a cast 19" as well, my speculation they weigh 29lbs front, 29.5lbs rear. you could also weight the whole wheel/tire and subtract the weight of the tires, if known.
I have them sitting in the garage but am lazy to weigh them. In the name of science and helping my brethren, I shall weigh them one day in the future. Hopefully. (I'm lazy )
