I am making a full spare. I want to pickup a steel wheel from summit but I dont know the proper backspacing of my 16x7 steel wheels that came on the 06 ST models.

Anyone know where I can get this info?

Better yet, Can i simply mount a 265/75 onto the spare steel rim under my truck bed? I dont care if it doesnt fit under there anymore, I will most likely store it in the bed.

 

I had an extra 265/75 bf goodwrench AT mounted to my spare.

I never got around to getting a proper full spare for my larger tires for like 3 years, but i finally did.

It still fits under the truck bed, with room to spare. You could probablly fit a 285/75 under there FYI.
