How much is needed in each tyre Chris? obviously it will depend on tyre size, but can you give a rough estimate for 33" tyres?Excellent 4 bottles of OKO tyre sealant.Perfect.
It's doesn't depend hugely on the tyre Chas, a hole is a hole. But I buy 4 x 1250 ml bottles and put a litre out of each in the road tyres and then all the 250mls spare go in the errr spare. Done. Very quick and easy, no mess and it will balance the tyre as it wears like Dyna beads. People can say all they like, but I have been using this since forever and never had a puncture, lost air, had balance issues or anything ever. Only benefits. I wish I'd bought a drum of it when I started all those years ago. It's in everything I have even trailers and quad bike.
Cheers Ben. Like all things, if I could source tube in that size cut to length all I'd have to do is thread one end, cut the original rod, thread the other end and pretty much that would be it. Oh and source some 30mm nuts. But taking a blank and boring the hole down the centre is a morning's work and a couple of tips too. Same with the rear ones. Strong adjustable PH rods would be a nice thing to be able to produce for people but the time taken would be prohibitive.
