I just ordered a set of Nitto Dune Grappler tires, size LT305/70/R17. Currently I have LT275/70/R17 size tires. Will the new ones fit?? I measured and they are no THAT much bigger, but now I am getting nervous...

The new tires are
12" wide
33.8" tall
The old tires are
10.8" wide
32.15" tall.
You're speedo will wbe off by about 4.9%
So you are basically going from a 32" tall tire to a 34" tall tire with just over 1" additional width.
Is the truck leveled?
