''giving it a bit''
on brand new tyres ??????????????
that's the reason the tail was trying to come out
tyre pressures are the same regardless of 205/45 or 215/40

What model are they on? and what is the load rating of the tyre?
I have ran with these and they have a soft sidewalls.
I would run with what RB5 says, i too found this from Toyo's technical dept.
I ran with 31 back 36 front on a classic, found this to be the best, you will need a good 500 miles on them to scrub them in.

The original tyres would have been 205x50x16 on a classic, so you are only going up one size on the rim and coming down in profile.

I upped my pressures today in a (vain) effort to get a little more mpg, but also to see what effect it would have
F were 30
R were 28
F now 34
R now 30
result: I nearly crashed!..handlingis completely different to before: the understeer is worse, but its alarming how quickly the rear comes around off the throttle
think I'll go back to the old pressures
