I'm interested in this also. Two of my bikes have had several punctures recently (tyres are on the way out to be fair), both of which weigh close to 25kg so I don't care about the weight increase (though surely it's less than 50g, will look into this also) and it's a pain in the arse to fix punctures with them. Thinking tyre replacements and slime in the tubes will last for quite a while longer!
