Can someone on stock tires tell me what their RPM's are at 15, 25, 35, 45, 55, 65 and 75 are? I am thinking of re-gearing and want to see the stock numbers, and then compare them to my 32" tires. I'm debating about going to the 4.10's or 4.27's on 33's, especially when it comes to hwy driving.

Thanks very much!

Dave

Joe,
Would you check your build sheet for gear ratios?

You doing a SFA swap? If not 4.10's is the lowest you can go with the D30A,plus you can't even get 4.27's for the 8.25.

Lots of variables in your request. Tire pressure is one since the OEM's blow up like a kids rubber baloon. Of course there is the speedometer error that some have and some don't and those that do have different ones.

Thanks for all the replies. I am possibly going with a d44 front and rear, checking out prices, etc. I know the genereal consensus in the wheeling world is to go 4.56's with either a 33" or 35" tire but I need to factor in the automatic tranny and the additional totque of the Diesel. Is it true that you want to go to a numerically higher gear in an automatic due to the slippage?

Thanks!
