So I have 38/15.50/18 and I do almost all highway driving in the middle of nowhere. So what gears do you recommend? In 1 1/2 to 2 years when the 38's are shot I will be going done to 35's so I don't really want to have to change the gears again. I was thinkin of going with 4.56's? Yes I know they are not ideal for 38's but it will be better then the 3.42's. it will work great for the 35's. Opinons?
