Engine RPM at Hiway speed

Tire size is 215/70/14. Height of tire is 25.25". Speedo gear is yellow-not sure of the teeth but I used the charts corresponding tire size to gear ratio to select the pinion. Trans shifts up to 3rd gear.

Same tire size on both cars ?


with zero slippage should turn 2600 rpms so your old car seems right this one is way off.
