just wondering would a set, of BFG A/T 30.5 inch fit on my 2006 ford f150 lariat with 18' rims 4x4 thanks in advance miller.

 

They will fit but they will be 1.5" shorter than your factory tires.

 

you can fit all the way to 33 X 12.50 on the stock rim on your truck with no rubbing and no level. That equates to roughly a 285/70/17.

 

Why do you want such a small tire?

 

o my bad i was under the impression that the tire that are all ready on my truck are 285's http://kaltire.ca/retail/tires/detai...TAT&cat=LT/SUV wich one is the biggest i can fit on my truck

 

If you add a leveling kit, you can fit up to a 35x12.50 using the oem wheels, but they will rub the control arms slightly at full steering lock. Without a leveling kit you can fit a 33x12.50-18 (305/60-18) or 285/65-18 (33x11.50).

 

ok so I'am thinking about a set of 285/65R18 but what is the stock size of my tire

 

Uh, you tell us. It's probably a 275/65-18. If you don't have the oem tires on it, the size should be listed on the door sticker.
