I plan to buy 5000 and give them a try after payday at the end of the month. one tyre has ~65G on it, another 45g and IIRC one has nearly 100g on it. So I think I'll go with this and leave the weights on for now, and maybe slowly remove the weights if this seems to work.
Worked out as ~1135 0.2g pellets to make up 227g (~8oz) per tyre which I think I'll need for 33s.
