Tires, Gears, Ratios and Charts

I was researching which tires/sizes I could/should run on my Jeep and found several places that had essentially this same chart for tire sizes and gear ratios combinations. I found it interesting. I'll let others decide if it's interesting or helpful to them.

Already in the FAQ section...and, it depends upon motor size, manual or auto tranny and tire size...so lots of options.

Nice chart, however only 5 of the gears are useable in the JK/JKU and the chart-

Is calculated on a 1/1 rario and no comparison between manual/auto trannys--and no mention of speed-involved

One of the most important ratios in the JK/JKU charts is the rpm values based on speed/O/D, with quite a difference between the 6-spd manual and the auto O/D

The rpms listed are extreme when not considereing Auto-speed/O/D

For instance, my auto/5.38/33" tires, the tach turns 2600 rpm at 70 mph-

Not very valuable chart-sorry

As stated the correct charts are in the FAQ. Thanks for trying to contribute though.
