Ive heard varying opinions on gear setups but i thought the consensus was that 4.88 gears were the appropriate setup for 33 inch tires. Now ive also heard someone say that they wished that there was a gear between 4.88 and 5.29, and that the ultimate setup was 4.88s on 32 inch tires. I was thinking i might go that route (32 inch tires w 4.88).Ive heard that 5.29s give a bit more pep but that its too loud on the highway since the rpms are really high at 75 mph. My truck is obnoxious with the flowmaster already, but maybe its worth it for the power... But now I will ask the pertinent question. Approximately, what is the top speed and rpms for a 22re with 33s and 4.88s? and the same for 5.29s?
