tire size for a 1973 dodge dart custom.

I have 195/75/r14 and my speedometer reads I'm doing 51 when I'm actually doing 45. If you have any questions just ask

The question is, is your statement your question.

Yes it is.. I was just wondering what tire size I'm supposed to have. I wrote the post on my phone and quite fast so I didn't get a chance to really think about what I was putting down.

LMAO! That's funny!

OK, the tire size looks correct to me. The speedometer gear is probably wrong for that tire. I do believe Year One still sells the gears. In there catolog, they have a chart. Tire size vs. gear size for the given ratio of the rear end.

I'll look it up for you. Give me a minute or two, I'll be right back.

For that tire and a rear gear of;

3.21/3.23 = a 33 tooth gear @ $35.99 repop or $79.99 for a new Chry. part.
3.54/3.55 = a 36 tooth gear, new Chrysler gear only, $79.99
3.91 = a 40, new Chrysler gear only, $79.99
4.10 = a 42, not listed.

Nothing in between, below or above the gear ratios above are listed.
