i found it to help ballence my wheel on my DR350 as they have a big rim lock in them and the slime or what ever counter acts that and got rid of my 30mph bounce, but only been up to about 70 on her so cant say about plus ton with slime
I've used it in the past and it never leaked again over the rest of the tyres life (3000 miles), did speeds well over 100MPH without any issues. Also had tyres plugged which have worked just as good too.
