i had new tires put on my truck today...of course they are tubeless
i have always had "tubed" bike tires
what are the advantages of "tubeless" tires...i have heard they do not hold air as long...if that is true ....why?
while i find it a pain to change out a tube on a road bike tire...what do you do if you have a flat with a tubeless mtb tire (i am unsure if there are tubeless road tires)???
a second question...i have noticed that on presta valves most do not have a screw on cap....you can get them and i have always heard you need to protect the valve from dirt and damage...i know the little metal piece on the valve does that to some degree....do you put valve caps on those little valves????
