Is there a tire height chart around anywhere that shows the height of tires in inches for different given sizes of tires?

Very interesting!!
I did some calculating, here is some references that answer many common questions
that people have about rregarding egearing and speedometer/odometer:
Going from stock tires 255/60/R16 (28"x10"x15) to 292/74/R15 (32"x11.5"x15)
will give you a speedometer error at actual speed 55mph (88.5 kph) that is -6.82 mph (-10.97 kph) , indicated speed will be 48.18 mph (77.53 kph).

Also if you have like me 3.73 gears it will be like having 3.27 with 32" tires.
If you want to regear so that you will have same as with the smaller tires you'll need to go with 4.26 (closest will be 4.10)

I used the two excellent links mentioned above combined with this:
