You can figure out the approx engine speed from the tyre size yourself if you need.

Just convert tyre size into diameter (eg 245/60/14, DIA = (254 x 0.60 x 2) + (14 x 25.4))
Then get the circumference, = pi x DIA.
Convert circumference into metres (divide by 1000).
Get the road speed in km/h into metres/min (multiply by 1000 and divide by 60).
Divide the road speed in m/min by the tyres circumference in m. This gives you the axle rpm.
Multiply the axle rpm by the diff ratio. Gives you the tailshaft rpm.
Multiply by gear ratio, gives you the engine revs on a manual or the rotor speed of a non locked torque converter on an auto (there will be a converter slip value if not locked).

For your case just assume it is a manual for a locked converter situation.
