MDS can I ask why your tyres got shredded? Was it a case of losing pressure because of a puncture and not knowing til it was all over? Reason I ask is that this seems to be a common problem (tyres get a bit flat, heat up, then go bang before you realise you have a problem) and a TPMS might prevent this. I can't afford 8 expensive tyres in one hit ( tug, trailer, spares) but still want to do some of the tracks and I'm looking for a way to do this. Going fast is not important to me.
Also, if BFGs got shredded, what alternative would have been better?
