Tire and rim weights are well known to vary by at least 10% and not be considered "wrong". Molds and dies wear and material density varies. But 570 VS 395 is a lot of difference. I suspect that the problem lies with the spec list being wrong. This also happens all the time. The people responsible for the document writing don't get/ask for the right data from the manufacturer side (which is also often a bit different then what the design side intended too. ) Andy.
