Chart concerning tires and rpm?
 

I'm wondering what gears i want to put in my one tons. Planning on putting lockers front and back. Tranny is a th350 with a np205. I know there is a chart somewhere but i can't find it. Thanks

Months ago someone posted a link that all you had to do was select your tranny. engine size and tire size and it was a chart of where your rpm's would be at so you can figure out the gear ratio you'd want

If you have a TH350 it is a direct drive in 3rd gear. Use the calculator on the randy's R&P page and you can see what rpm you'll be at in what gear. If it has a lockup TC, the rpm's will be in the "manual" window. If non-lockup it will be the same as the "auto" window. Not much difference either way. Sorry I haven't seen the chart you reference. A lot of gear selection has to do with how you will use the rig...

Looks like i'll be going with 4:88s

it seems with the 39.5" tire at 70mph(110kmh) puts me at just under 3k

And the truck doesn't see highway. for very long anyways.
