Your car originally had 6.70x15 tires, that simply equates to a 28” tire. I run 215/75r15 Hankook tires on stock 4.50” wide wheels, with a 3.9 gear ratio. The speedometer reads correct in a school zone radar indicator. I’ve had it up to 80 mph. You initially said you had 195/65r15 tires and a 3.27 gear ratio. ? With 28” tires and 3.73 gear ratio, you could be driving 70 mph at about 3130 rpm. Rick D. That is really interesting. I was under the impression that a 1950 Plymouth Deluxe had 6.4 x 15 tires as indicated by this website: http://www.classiccardatabase.com/specs.php?series=4830&year=1950&model=28195 Maybe they were wrong? I will do more calculations. Thanks! Quote Link to comment Share on other sites More sharing options...
