carl ekblom Posted November 7, 2015 Report Share Posted November 7, 2015 I did some measurements of rear tyres. Here is the result. Michelin Competition tubed type, used but OK: 5.7kg Michelin X-light new: 5,8kg IRC TR011R tubed type, new: 5,0kg So, X-light isn´t so light....anymore.

nigel dabster Posted November 8, 2015 Report Share Posted November 8, 2015 what is the weight of X11 standard? Quote Link to comment Share on other sites More sharing options...
carl ekblom Posted November 9, 2015 Author Report Share Posted November 9, 2015 All my old X11 (tubeless) are sent for recycling so I´m not able to measure. An inner tube is about 0.7kg. On my pre 65 Royal Enfield I feel that IRC may not be as good as Michelin on stone and rocks but feels more stable sideways so the result will be about the same. Considering the weight difference I think IRC is an attractive option, specially that tubed Michelin not is available anymore. By the way, IRC is good at moss when wet. Perhaps better than Michelin. Are there still issues about tubless IRC? Carl Quote Link to comment Share on other sites More sharing options...
guys Posted November 9, 2015 Report Share Posted November 9, 2015 (edited) It's only logical that a tubeless tyre is a bit heavier, to make it air tight, it needs an extra layer of rubber of on the inside. If you want a fair comparison, you'd have to add the weight of the inner tube. Edited November 9, 2015 by guys Quote Link to comment Share on other sites More sharing options...
