i bought a slime filled tube on my tour ov the states and mexico last winter.it went down yesterday,and i found half a dozen thorns in the tire,and the punctures were marked by a green blob.i repaired the punctures but now i think if i had just pumped it up theres a gud chance they wud have sealed.the efect on the steering is minimal.and the tyre dosnt deflat at all.
i was very sceptical at first,believing it to gud to b true.
