Schwalbe Snow Stud, Continental Tube - Woe is Me

I have found continental to vary very much in quality, I had a brand new tyre split at the sidewall and the tubes arent as good as schwalbe, michelin or vittoria/geax, (but better than spesh).
if you can get out west tomorrow, I can find you a tube to fit if you're desperate

Thanks for the kind offer. But I am not too desperate. I was just keen to whizz up the road on the ice. Thanks for the info about the tubes.
