[WasavaTyres]

I can vouch that goodyear tubetype tyres can safely be used as tubeless tires b'coz thier tubetype tires also have a halo butyl lining inside the tires which prevents air from permeating,resulting in loss in air pressure.Would not know about other brands for sure. A simple way to find out is to look at the inside of the tires. Tires with halo butyl linign would have a texture-effect on the walls,whereas plain tires would look just that plain on the inside with radial lines on the walls at the most.
