Putting together my Vespa vbb front end and when mounting the wheel and tyre and spinning it whilst the bikes on the stand it appears the wheel doesn't spin 100% true, slight wobble to it.
Took the wheel off and tighten the hub that sits over the brakes as much as I could but even then when I span that without the wheels attached it looked like it was perfect. The Hub was a new part so could be the issue but i took it off and sat it on a flat surface and couldn't see anything visually distorted with it.
any ideas?

your wheel rims might be bent.
check these.
Also check your rear wheel as well whilst its on the hub, then remove and try it on the front hub.
These checks should confirm if the rims are out of alignment.
You might need to buy a new set of rims

Im surprised that you say SIP has let you down. Ive always found it to be very good.

rims often have slight run out , an also could be tyres un-evenly seated on the rim an thats putting your eyes out .on a warm/hot day , let the air out of them,then re-inflate to 40-45 psi an bounce them on the ground hard ,working your way around the whole circumference .this will flex them an hopefully get the edge to seat up on the rim fully .then release excessive psi til at the proper pressure to run on .

What is the correct PSi to run on these 8 in tyres - In fairness these are brand new Michelin White wall tyres, new inner tubes and new split rims. I might have to double check how tight and even I bolted the rims back together once on the tyre.

Believe same as 10” so 25 rear 18 front or even a little less.
A slight run out on the rims/tyres you really won’t notice on the road, if it goes up and down (as sometimes happens when tyre not seated great) you will notice.
Look out for some second hand 8” rims, these are really really solid and probably never get bent!
