Alright, I have a 2001 Ford f150 4WD and I have a 79 ford bronco that I dont drive at the time. The bronco has 15" rims with 33x12.5x15 that I want to put on the f150. I have read some threads that say 15's wont fit on a f150 but I put them on and they almost fit. I am just wondering if i buy some wheel spacers will they end up fitting? Let me know please....

 

No. The two vehicles have two different bolt patterns and as you found out, they won't fit over your brakes.

 

The diameter of 15" rim is obviously 15" which will hit the brake caliper so like Wandell said they wont fit because of that reason and the other reason is that every vehicle car or truck has their own specific bolt pattern. You can have 2 trucks with a 5 bolt wheel but the space that the studs are split apart will be different. A 97-03 f150 has a 5x135mm bolt pattern.
