Talkback: Tannus Musai solid tyres – first look
The thing about stuff, any stuff, is that it weighs a lot more than "no stuff". To that end every solid tire is going to weigh a lot more than a bag of air. Admittedly savings can be made by not having any puncture resistant heavy threads or valves but I reckon the increase in weight has got to be within the 20 - 30% range or they're a definite no-no. Would like to see a full review on them though!
