Need Help with rims

I have this red Jonway and I would like to replace the original rims. I have seen similar cars but nice rims, the facts I have are on the original rims. I hope someone can help me on which ones to look for.

The yellow one, I wonder which rims are on and which ET / offset as it is very similar in the wheel arches. Have seen that you use 2 + 4 or similar so what would I go on.
I want nicer rims than the original…

I forgot this picture with the ET

Now the new rims in place
