I am currently running stock tires 255/65/17 and looking at upsizing to 265/70/17 and wondering if I am going to have to clearance issues. Tire Calculator on Discount Tire says there is an approx 1.56" diameter difference. I measured it on the truck and it looks ok, but looking for some more expert feedback.

Thanks

 

They will fit fine.

 

That's the size (265/70-17) I put on my '04 last month, absolutely no issues......
I'm thinking I left a larger tire on "the table"!
