Does anyone know what the wheel offset and lug pattern is on a 2013 Tacoma with 18"wheels ?

I'm thinking of getting new wheels and i need help with the wheel offset and lug pattern. It's a 6 lug, but I don't know the spacing or the offset. I'm completely stock, and I'd like to keep it that way without any modifications. Thank you for your help!

 

18 inch wheels are not a common stock size for Tacomas. X-Runner came with them. You might have after market wheels. Stock 6-lug are 6X5.5 bolt pattern. Backspacing on stock wheels are 5.25-5.5.

 

They're not aftermarket, I bought the truck new. The limited has 18"x7.5 rims. Not sure of the offset and backspace and all that. I would like to by Xd Series rims, but they're 18x9
