Higher number = shorter ratio
When I go up to 35s the 4.11 will put the final drive line close to stock ratio. Since I have 3.73 the 33s I have are fine.
With Sarah since she has the 3.42 her 33s are starting to stress things.

isnt bigger always better,lol.
ratio is the number of times the drive-shaft has to turn for one revolution of the tires, so in third gear the engine would be turning 4.1 times faster than the tires which is a torque multiplier. so generally the engine would be easier able to push the 35inch tires with 4.10'* than 3.73. little expensive though on a 4wd you have to change both obviously and program the pcm

your tires are 32.8 by 9.2. stock is almost 32. so 33 is almost negligible for wear.
