Need some help with wheels and tyres

[Magical Trevor]

Howdy if youve read my previous posts ive been looking for a set of wheels for my silvia i know its a 4 x 114 pcd and et is how far it sits in or pokes out..? but whats the maximum i could use?
ive found the wheels but the fitting is 4 x 114 et 10 16 x 8

Will these clear the arches on a car running no spacers and lowered no more 40 mm? what would be the size of tyre to buy to fit these? profile wise?

Thanks
