would 205s fit on an 8in wide alloy??

just for a temp fix to get the car home

my mechanic needs it out the garage soon as and ive been delayed with my delivery of new tyres

and have 4 205/40/17 tyres in my garage

and ive sold my diamond cut rims so its stuck on axle stands

and i cant just borrow a set of rims,due to having my new brakes fitted just now,not all will fit
