The only way you have 5x4.5 bolt pattern is if somebody redrilled them as ALL stock S-series are 5x4.75 and since you said the ones on there now are a chevy rim with chevy centercap they would be 5x4.75. 2wd or 4wd makes no difference.The reason your ranger rims won't just quite fit is because they are 5x4.5
old post but I would like to know what you ended up doing for rims? If you figured out what you have or you still need help.

 

yeah, it would be nice if someone updated their OP.

maybe he was embarrassed by the discovery we were correct about his bolt pattern?


***edit*** so i was kinda curious about this guy (& his thread)......did a little diggin'..............

turns out he's flaked on a few threads he started.

besides never following up on this one.....

started a thread about valve lash adjustment on 9-22-10

started a very similar thread on 9-25-10, ranated a bit for a couple of days.

but never finished either one off.

then for some really stupid reason, he does a wrap up of the issues in his welcome thread almost 2 weeks later (10-08-10).

and that was it. never been back since. guess we'll never know what happened.
