would love to know myself... I can't imagine a nail would cause a massive loss of air with the tubeless tire still mounted.... seems like you'd get a slow leak...But are the tubed tubeless tires more likely to blow out than tubleless tubeless tires? Haven't seen an answer to that one.
I'm looking at the Pirelli Angel Street. I can't find any negatives on these and have never owned any Pirelli. I see the recommendation for 180/55 but was considering a 190/50 but saw some people on other forums said with the slight stretch it makes them balloon a little bit but not really sure if for the riding I do, if it would be an issue. My buddy with the Buell bought a 180/55 Avon ultra 2 and it looks substantially beefier than my Metzeler and a lot wider. I want the slightly wider look now and would consider a 190/55 but since they are taller sidewall not sure if they would give me fits with the traction control and ABS??? Anyone swap some 190s on their bike?????This are the tires recommended by BMW Motorrad.
