100,000 on the OE tires!???
I couldn't run them over 10,000 miles, mine were terrible.
Can't go much taller due to the wheel wells etc. Most go up to a 245-70 and that's it.
I contacted a guy who has a 6 speed but then I remembered that the CRDs are different than the gasser's since they sit farther to the left. Have to do some looking to see what all would need changed. It would take some time to swap both out, rear would be a snap, front takes some time, about 3 hours or so if everything comes out the way it should and thats with a couple of little short cuts.
Funny you want to go to higher gears and I want to get my lower ones installed soon!
I've been here 5 years and came due to the state offering me a position here, otherwise no way!!!
When you have time maybe we can meet and look things over closer to see what all would need to be done if anything except swap diffs and CVs
I live off 475/Reynolds/Airport area
Mine gets the best at around 2000 RPMs 1650 or so its a dog and bogs bad!Difference between gassers and CRDs
