| Following on from the thread on Road Speed calculated from engine revolutions 
per minute, I came across this link on the Buckeye Triumphs technical page: 
http://www.buckeyetriumphs.org/technical/technical.htm
for a 'Road Speed Vs Engine Speed calculator' authored by Dan Masters: 
http://www.buckeyetriumphs.org/technical/Calculator/road_speed_vs_engine_speed_calcu.htm
Its set up with TR6 data, but tire size, rear end ratio and gear ratio are 
available for revision for your car's details. The table will then 
automatically calculate the rest.
I hope you find this a useful as I did.
