Tried to find a previous post on this with no success. What is the largest tire I can fit on my truck with factory rims?

Thanks,

The topic was the same; largest tire size.

Sorry, my truck is 2wd

I'd try 265/75/16 if it's a 2wd. I'm not sure if anything bigger will fit without trimming or scrubbing.

yes 265/75/16 is your limit without any rubbing.

I know that you want to stay with factory rim. But, FYI The tire size on my truck is 295/45R20. I have no issues with rubbing in my wheel wells. I think you can safely put 285 on your truck, but confirm it with someone else first.
