i know its been asked already..

but i cant remember wher i saw it.and i used the search and didnt get to much, unless i typed it wrong..but wat is the correct offest for a 20x10 rear wheel to get them to fit correctly and not stick out of the fender.or even a 20x9 or 20x9.5 mabye??? its o5 cts, i ordered a set from work.they fit but the offset is to much.one guy they will fit,and another said no they wont..so im sending them back..lol
and i dont want 8.5 in the rear either to match the front..:tisk:
im hate to be asking this stupid question again.but i need some assistance please folks.lol
