What are the differences between “clincher” and “tubular” tires?

if you get tubular tyres with removable valves you can put some sealant inside them which will often cure punctures for you often without you even noticing.

i tend to find that i change tires on the second puncture but i have read of people finding eight sealed holes after a ride on a (mtb) tubular tyre. with a clincher this would probably have meant stopping to change or repair the inner tube eight times.

tufo and stans sealant words well but is not all that cheap. for economy and even efficiency, “home brew sealant” (google) can be used containing liquid latex, such as sold for making masks or as a sewing glue, a drop of ammonia water and water if thinning is needed, with some added fibres such as cornflower, pepper, glitter or artificial grass used in model train terrains.

sealant can apparently be used in clinchers too but sealing a thin tube, rather than a tyre with threads, can be less effective and or less permanent i presume. i repair my clincher punctures but seal tubular punctures.

the 30 grams to 50 grams of sealant if added prior to puncture will reduce or remove the weight advantage of tubulars, but combined with the fact that tubulars can be ridden with very low (or even zero) air pressure, means that punctures often will not stop you in a race, or on your commute. the puncture will usually seal and you can just keep riding on a softer tyre.

tubulars can be pumped up higher, eg to 175psi for use on smooth surfaces such as velodromes. the roads around me are good so, mainly for puncture resistance, i have ridden on tubulars at about 145psi, a pressure not allowed by the clinchers that i buy.

i doubt that others will do the same but, i find that 100 yen store (dollar store) leather glue works for me, providing an adequate tyre to rim bond but i am not a racer. i get my latex at that price too.

the biggest drawback of tubulars is that one should really carry a spare tyre and not just a spare inner tube for when the puncture is too big for the latex to seal. that said, i feel pretty confident that my latex will hold out or seal enough to allow me to get home.

due to the ease of carrying a spare inner tube and repair kit, given the choice i think i would probably use clinchers since i am not a racer. but i bought some cheaper-than-clincher, deep-rimmed carbon tubular wheels and i enjoy using them often. if i were racing, i would save my tubulars for race day and use them in preference to clinchers for their slightly superior ride quality and self-sealing properties mentioned above.

addendum apparently some people put sealant in the type with non-removable valve cores (though perhaps not containing fibre) and that it is also possible to inject sealing adhesive directly into puncture holes, i believe.
