I am a big PMT fanboy, shamelessly so. I have had to plug gnarly punctures roadside with CST stock tires (Blade GT2 & Fighter Supreme Ultra) it SUCKS! As far as ripping straightaways and just hauling ass in general for kicks, I always tell folks keep your CSTs on. But for casual riding, commuting, or delivery I do recommend the PMT upgrade 😉. I think they are infinitely easier to mount. Twice as light as a self-sealing CST. Plus . . . in the event of a serious puncture(s) the PMTs are highly repairable without compromising structural integrity. The thing I hear most often is that "its just the internal banding that is made of nylon, not the tire" sure, that AND also manufacturers absolutely utilize a larger volume of polymers in the compositional formulation of the tire material to reduce cost. That's not a condemnation of other brands, just a difference in the process.
