wheel backspacing

[droppedoffroad]

Going to do a 2/4 drop on my truck and will be running 15x10 rims on rear. My question is what is the correct back space I need to where the rims DO NOT stick out my fenders? I want to to be flush at most. Please I need help with this asap!
truck is a 98 ext cab

Thank you!!

stock is about 6" on my wheels... if that helps any... haha I'm not a rim and tire guy.

You would need a 4.25" front space so a 5.75" or higher bs would work depending on tire size. I would say a 6.5" bs would be the max. bs I would want on 15's so the wheels don't looked tucked in too far.

Blue im not sure on exact tire size but prolly a 325/50 15 for tire as I plan on a nice meaty tire. The tire will prolly be the Mickey Thompson drag radial which will need to go on a 15x10 rim

I would probably stay with a wheel close to a 5 3/4" bs to a 6 1/4" bs, too much backspacing with that tire size will rub your leaf springs.
