Comparing Challenge's Paris-Roubaix variants, 285g for the clincher version, 330g for tubular. Figuring that a latex tube would be about 75g, you are still coming out 30g ahead with the tubular. The tire I wish I could go back in time and try was the Clement Campionato del Mondo, which was fat but only 290g altogether. So you pretty much get the tube for free compared to the Challenge Paris-Roubaix clincher!
Del Mondos never weighed as little as catalog spec. Always over 300 and 330 could happen. Just weighed a very well worn Challenge P-R. Missing tread weight probably much more than weight of glue residue. 346grams. Weighed a well worn clincher P-R and got 310grams.
Mavic rims always always weigh just a lot more than spec. Not unusual to see weights more than 100 above spec. Weighing tires is a waste of time, nothing you can do about it. Rims, well, you can at least avoid Mavic rims over 500g. Or just avoid Mavic. Who owns the company now? Are they going to continue? A 360 gram rim will just plain feel light, a Mavic will not.
