205/50/16 will fit but they're change how the car handles as the Plus rim is a 7.5j and the 205 was designed to fit the standard turbo 7j width.

Plenty of 225 available on demon Tweaks.

Ar...I thought Plus wheel and standard wheel were of the size width (was referring to Useful Info), and now for 7.5J, perhaps I should try harder to look for 225 tyres.

Thanks for the heads up.

From ePER, the Plus wheel is listed as 7J. I took a look at Yahoo Auction in Japan, there's a listing of Plus wheel, in which the pic shown is 7J as well. Attached pics of ePER and Yahoo Auction.

Do you think there are two different Plus wheels various in width?

7j for the turbo, 6.5j for the n/a models, any joy with 225 tyres?

Since you said 7.5J, I was thinking 225 would be more adequate so I placed an order for a set of 4 Bridgestone 71RS 225/45/16, which will be shipped from Japan to Hong Kong. Costed me a kidney

Yes it's crazy shipping costs all over the globe at the moment but at least you've found the correct size tyres for your Plus rims, and to be fair Bridgestone aren't too bad and do last in comparison to track compound.
