OEM Sized wheels

I am trying to find out what size wheels are OEM for this 1999 Toyota Tacoma SR5 4x4 . They are 6 lug , Thats all i know . The prior owner put on these wheels and they look like they stick out 8 inches on each side . I would like the tucked in look . Thanks
And why does this not show my trucks picture ?

 

16x7 +30 offset

or

15x7 +30 offset

you'd be fine with up to +15 or even a +0, if you're running 265 width tires ( I assume you will be)

 

Thanks for your reply , at this point Im not sure what Im doing
