Re: Speedometer/Odometer & bigger tires
There are some issues here, some websites give different speedos for
the same gear and tire ratio.
Also when you buy a 33" tire it is not always 33" but maybe 32.8 and
then with wear it will decrease.
Add to this the air pressure you put in the tire.
This is the best link so far
http://www.jeeptech.com/javaAps/Speedo.html
But maybe the best solution is to say that you are running:
this <gear ratio> with this <tire> and the <size>
I am sure you will get a better answer from the pros here.
I have just regeared and am playing with the same problem. I am
running bfg 33 that are infact 32.8 and 4.56 gears the 36 tooth is to
fast by 10km at 100km. So to correct this I need more teeth to
correct the problem I just ordered a 38 tooth. I will test it with
my GPS.

The speedo gears are simply a ratio change to correct. If you are off by
10km at 100km/hour, then your speedo gear is also off by 10%. Yours is off
by 10% so you need to increase the number of teeth on the gear by 10%. If
you have a 36 tooth now, the closest one to fix your speedo would be a 40
tooth gear (36x1.10 = 39.6).
