When i first bought my truck i said the same thing . First i bought 31s and a spool for rear , lasted about 6 months . Then i did a sas 529s and a front locker , and 34s . Another 6 months whent buy then dual cases and 35s. That lasted about a year and a half , then 36s and four linked the rear with coil springs. What i am trying to say is if you think 33s is enough buy 35s , because once you start building its like drugs and you cant stop. It took me three years and four thousand dollars in tires, and parts to come to that conclusion. So save yourself some money and work, and go with 35s and gears.
