Is there a way to find out what gear ratio my truck's diff has? I know I could call a dealer with the VIN but I was wondering if there was any other way.

You can look in the glove box and find the axle ratio on the information sheet on the door, or you might find it on the radiator support under the hood.

This is with 265/75/16's.

Here is what it should run with 3.55's
