speedo drive gear chart somewhere?

[volaredon]

I have 2 Jeeps that I need to know what drive gears should be in there; one XJ and the other a TJ; both '97 models.

1) TJ, 4.0, AX 15, 3.07s, 235/75-15s
stock size was 215/75-15. I have had a few tickets in this thing in the 10 years I have had it, and the ****tards always write me for a higher speed, than is indicated on my speedo by 6-8MPH. go 68, get wrote up for 76. go 65 get wrote up for going 72. go 63 get wrote up for 69. go 68 and get wrote up for 74; I'm tired of paying them. I don't seem to be going any faster than the flow of traffic. not at all like I am flying by everyone.

1a) same Jeep, what should be in there with the stock 215/15s (that is the gear that should still be in there; I have never touched that)
1b) same Jeep same 235/15s but with a possible gear swap to 3.73s,

2) 97 XJ, 4.0, AW4, 3.55s 2a) with stock, 225/70-15 2b) with 235/75-15s. (1-1/2" taller)
I just swapped tire sizes, and as compared to my 01 XJ which it replaced; also 4.0, AW4,3.55s 235/75-15s the 97 seems to be a gas hog. IDK if it's just the possibility that the odo is reading wrong with the bigger 235s?

My first owning a jeep so I have no idea, but ya they are expensive and for that price they better last.
