Which gear ratio do i run?

I bought my Blazer with a 3:73 ratio witch is obviously not enough for my 38 inch tires. What is the best combo here? I do drive it daily so keep that in mind.

Which trans are you running? if a final 1-1 then I would suggest a 4.56-4.88 if running an overdrive then I would step down to a 5.13 or a 5.38
