I am considering getting some Rota Slipstreams in this size

16x7 5X114.3 45

will the tires I already have fit on these wheels?

 

yes

 

yup but you will be pushing it
tell me how they fit i want to get a set of 18*7.5 with off set of 45 but i am lowered and don't want to rub i also have a -1 camber all round so if it is just tight it will fit pertect for me please update thanks

 

it will be totally ok.

 

I am not sure if this matters, but the car is lowered a bit with H&r springs and Koni Yellows.

 

sure they'll fit
