4.11 or 4.56?

I'm on the horns of a delima...which ratio? My Wrangler is a 2000 with a non overdrive automatic with lockup converter. Tire size is 32.7 inches in height. I do some beltway driving but mostly inner city with occassional trail riding. I've looked at grimmjeepers gear calculator but my concern is sustained high rpm on the beltway. Does the 4.0 have any issues with sustained 3000-3500 rpm? I've never thought of them as hi revvers...

Go with 4.56 if you ever plan on moving up to 35s. If not, stick with 4.10. The 4.0 is very happy with higher revs.

Do you think 4.56 would be too much for 32.7 inch tires? I doubt I'd ever go over 33s.

I'd go with 4.10 gears if you're staying with 33" tires.

Based on that stick with 4.10.

I just sold my jeep with auto trans and 32inch tires.. And I had 3.73 gears.. And i had to HOLD the brake pretty hard setting at light due to the jeep wanting to GO.. So I could not imagine 411 gears with the 32s.

Interstate speeds the engine was up there in the RPM range. More so than I liked, but those trips at 70+mph are rare for me in a jeep.
Around town i really liked the gears and could have used 411 just as well.
I had on it a light set up of street tires and light aluminum rims..

I had a set of 35s on heavy steel rims that Were just to large to fit on a stock jeep or I would have tried it.

So if your tires are mud tires or heavy then the 410s will really help

I run around 65 on the highway...so it sounds like 4.11 gears is the way to go. Thanks all! =-)
