Why not calculate ?
215/65/15 tire circumference is 2075mm (roughly)
assuming manual gearbox, 5th is 0.775 , axle/final drive is 3.882 you get such table
by your numbers either your speedo reads low or your rev counter high. Or something is different from my assumptions with your gearbox (auto ?)
Yeah I know, it's 2 years late and the OP's only contribution here but maybe others may want to know.
