Well i've used tubed tyres for the last 2 years without a puncture, (4500 miles+) and i've never had a explosive blow out failure in 40 years of cycling. Always slow release of pressure.
I suppose if someone has invested in all the cost of tubeless tyres, wheels and the support systems required they may feel they have to be positive about them.
I'm trying to focus on the reality of use, not the constant promotion of the latest marketing proposal the cycling magazines (catalogues) trot out.
They score products from 1 to 10 .... when was the last time you saw a "6" ......
If tubeless tyres are the new, lightweight, puncture proof product the cycling press say they are i'm sure they where used by all the teams in the Tour this year ... and those old fashioned Tubulars where consigned to the bin ....?
(Used to love the smell of the glue, while i stuck my Tubs to their rims.
