from this site:
I'm running 32" tires with stock gears and a T-5 transmission.
How could I tell if this was a configuration prone to Lugging?
TIA,

No Tach, No YJ. Only a lowly 83 CJ7 :-)
Do need to get a Tach though.

RPM...
I run 33's and 3.31 gears and if I use 5th on the highway at 65 mph, my revs are too low, about 1800 or less and the engine lugs and just drinks gas.
If I use 4th, I turn 2300 rpm at 65 and the slightest twitch on the gas pedal is all I need to adjust my power for wind or up hills.
When in 5th, I need almost the whole travel of the gas pedal to do minor power adjustments, this tells me I am lugging the engine.
Basically if you have the pedal to the metal and aren't increasing speed at a good rate, you are lugging it and your gas mileage will suck.
I get 19 US mpg highway running in 4th. Put her in 5th mostly for the same trip and I don't get even 15 mpg.
