I did some math and was surprised....
From 32" (265's) to 35" (315's), with 4.10 = 3.75
From 32" to 35" with 3.73 = 3.41

With my 315's and my 3.54 gears, I'm at 3.27 rear end ratio. Works ok and gotten use to it (not towing heavy) but it sounds like a pretty tall gear ratio.

didnt catch this the 37's slightly rub on the my long arms. and now driving the speed limit at 65 I use 5th gear just dont like doing it for a long trip. 6th gear at 65 is around 1500ish rpm 75-80 is the 1800-1900 rpm range.

Thanks.
Same question as Dezl-Andy above.....
What is rpm at 70 mph, in 5th gear?
Probably 2100+/-.... which is no problem at all, right?

sorry I guess I need to pay attention more been busy these last few days with work and then new ball-joints and hub. 5th gear at 65 speed limit here. I'm at 2kish. at 70 its just over 2100. now with the 37" tires. I have a gps that I got close as I can with on my speedo with the smarty. I know there is 1-3mph error on this. I have gotten in the habit of using the GPS for my speed. I dont really Tow much anymore. I have a good turn over ball in the bed that is collecting cob webs.
