Optional tire sizes for 2009?

I have a stupid question and I know I am going to get all kinds of answers. I have a 2009 Tacoma and I know they came with option tire size when they came out. I am the second owner of the car. I was wonder how can I find out what size came out on the truck the size the door sticker says or the option size?

 

You want to know what size tires was fitted to the truck when it left the factory? The doorjamb sticker will have the most accurate info.

 

it says 245/75R16... but they also a optional size they came out with on the truck which was 265/70R16.... I know if it came out with the optional size it wouldn't say it on the doorjam stickeer
