I have a 85 dodge ram 50 and was wondering if 31x10.5x15 tires would fit onto that rim the tires on them now are p215/75/r15 Any help would be awesome

 

i guess it would depend on how much clearance you have with the tires that are on it now.
31x10.5x15 are 3" taller and 2" wider. which would take away a inch and a half of clearance and put it a inch closer to rubbing on the inside of the front.[>:]
