Peter,
have a look at the Tyre Bible
In short most 4wders refer to tyres by their diameter in inches. Use the info from the tyre bible above to work out the diameter of your original tyres in mm then convert to inches.

But I have found tyre height varies from manufacturer to manufacturer. 31" cooper ST's for example didn't stand as tall as my 31" BFG muddies. Seemed like almost 20mm difference in height!

Peter,
There is a good rolling diameter calculator to compare tyre options at:
http://daihard.org/
Go into the TUNING section and then WHEEL SIZES
285/70/R16 means - Tread width = 285mm
Profile height = 70% of 285 = 200mm
R16 = 16 inch rim
Regards,
Greg

Peter,
Greg has outlined it spot-on.......one thing always stuffs me up though; why do they have to mix imperial with metric (ie: 16 inch wheel, but mm used for the tyre width and profile!!!!)
It's like telling somebody there speed in furlongs per fortnight...haha
So, to add to what Greg has said, you now need to work out how many mm there are in 16 inches, then add 400 to that figure to give you the overall diameter (in mm) of the tyre.
