Gear Ratio for 35's

You ain't cruising at 2500 rpm doing interstate speeds in a TJ on 35s unless you have significantly more power than a stock 4.0 gives you.

Maybe for short distances downhill with a tailwind but otherwise, not happening.

I can maybe cruise at 2500 rpm at lower speeds in 5th gear. Higher speeds require more power than you get at those rpms.

With my old setup, I was going about 70 with 35s/3.73s and OD off.
