tire to backspacing

ok if i want to run a 12.5 i gota have alteast 3.75" bs? and for a 10.5 ill be ok with 4" bs? im not worried about rubbing up front just dont wana have a problem with the rear. and if ne one knows some one who makes a 16" rim with 3.75 bs and less that would much appreciated.

I ran 31x10.50 and 33x10.50's with stock wheels and she looked good IMO, you will have to adjust your steering bump stops mine turned too tight and the tires hit the LCA and anti-sway bar. And when I stuffed all the way in the rear the tire rubbed a little on the inner fender well

Here's 2 pics to give u an idea what 5.25 backspacing looks like

33's on with 4" lift


31's with 4" lift


I ended up going 3.75 back spacing in the end but only cause I didn't like rubbing my anti away bar in wheeling trips

http:// this is with 16" crown vic rims with 265-75-16 and i rub like u say but it dont bother me but wen i go to a 6"longarm im wanting that wider stance

31's with 3.75 back spacing


Just to give you an idea how much the difference is between 5.25 and 3.75... Here's how far stock stuck out

so i wud be good with 4" with a 12.5 rite? wat is ur full rim and tire spec cuz thats wat im looking for

Those are 31's on 18x8's with 3.75 BS... A 1/4" won't make much difference, I think 12.5'a would be fine

If you want steel cragar is a good steel rim.It shouldn't be a problem to find a 16 with 3.75 bs
