v90

These are the rims i ended up getting https://www.jgs4x4.co.uk/defender-modular-steel-wheel-black-16x7-set-of-four/ I was trying to get et0 but didn’t realise until after i paid what mistake i made I could allways go down in tyre size slightly, i wanted slightly thicker than originally tyres for a more aggressive look, how much do you think i should go down?

I brought some 16x7 rims but didnt see they were ET08, i wanted to put 285/75/16 tyres on but now im worried im going to have rub or the tyres will be well more into the wheel arch, what can i do, also im on standard lift but was looking to go higher
