I am looking to purchase some new tires. I have a stock 85 extra cab pickup and want to try out those BFG MT 31x12.5 15 tires. However, i do not want to find out they hard way that they rub.

where are you worred about them rubbing? leaf spings,fenders? I have 33x12.5 15 and they don't rub when I turn the wheel stop to stop. they do rub a little when I flex it but I also have a 3 inch lift.

You will be fine with the 31"but I would stay with 10.5 or 11.5 they may rub a little bit on hard turns nothing to worry about ;D but the 12.5 you are gonna have to get a B/L or a S/L or cut the fenders alot

I ran 31 x 10.50's and they rubed on my 85 with stock suspension, but my springs were all  up. Might want to look and see how saggy the springs have become over the last 19 years ;D |

Okay,
i am confused. Why would the 31x12.5 rub fenders ect.. when a 33x12.5 does not. I understand the 33's will only fit with a lift but the 31's fit without a lift. Are the 12.5 to wide for the truck? Is that what causes the rubbing?

Yes, it is the width of the tire causing the problem. The 12.50, when you turn the wheel, will rub either the inside or outside edge on the fender. There is more tire to turn - so it will rub. When you lift the truck, you lift the fender out of the way - further up the wheel. Naturally, the higher up the fender is, the less chance of rubbing the tire during normal driving/turning.
