Here is the deal-
Less than a year ago I went from 255/70 16's to 265/75 16's. The stock 3.73 gearing is a little off for my tastes and my in town MPG sucks ~12. It shifts into OD way to early- 40 MPH. 60 MPH is 1800 RPM. My speedo was recalibrated for 31 x 10.50s, so its fairly close. My tires are 31.6"
There is no way the wife will let me buy new tires. I really want 33's and 4.10s, but can't do it. I just spent $700 on those tires not 10 months ago, and they aren't worth squat now.
I soon will be the proud owner of 4.10 gears front and rear. I can save these until later, but could I run them now? I know it will be a little low, but is it too low?
