do bigger tires affect the fuel gauge at all or does the fuel gauge stay correct?

What makes You think that it might affect the gauge? Bigger tires will most likely affect MPG, but the volume in the tank will still be the same.

the reason i was wondering was because there are so many computers in our truck i just dont know if the fuel gauge would be affected by the tires like so many other things.

The only thing that will read wrong with big tires is the Speedometer. Tachometer and fuel gauge will be as accurate (or inaccurate) as they were before.

It may go down faster due to less MPGs, but YMMV. ):h
