Actually quite a bit heavier, mainly because of the thicker beading to seal the tire to the rim. For example the new Conti 5000 25c tubeless is 300 grams vs the clincher at 215 grams. This of course will vary from different manufactures but that adds quite a bit of rotating weight. Now of course you need a tube for clinchers which adds some weight but it's offset somewhat but having to add sealant to the tubeless version. Also in general tubeless wheelsets are a little heavier due to the fact of the bead lock but that also varies from company to company. Some guys I ride with have had horror shows on the side of the road after slashing a sidewall and trying to fit a tube to get home. The tubeless valve stems are some times impossible to remove without pliers so you can fit a tube among other various issues.
