Tyre sealant's

[Skippernick]

I run "slime" the green stuff,  in my rear tyre at the moment due to getting a large slit in my 1000 mile old bt23 and being to tight to buy a new one put that in just in case it goes.
Well it hasn't yet but i haven't noticed any balance issues either, again i'm not a fast rider but i don't hang about either.
My dealer said they have  had customers come back from touring abroad with 3 punctures and never noticed!!
