If you've now got 205 tires on the original narrow 240D wheels, they are way too big for your wheels.

175-14 and 195/70-14 provide the same diameter and consequently same speed readings. When you had 185/70-14 you had smaller diameter than required and now with 205 you have larger, so you've never had an accurate speedo/odo.

I have the 205s mounted on bundts I got off of a 1985 wagon. The speedo is hopelessly inaccurate anyway with the different tranmission. Its about 8-10 mph off past 30, and between 5 and 6 in the lower speeds. For the moment, I am measuring accurate speed with a GPS unit, which is where I am getting my numbers.

If you bought a 240 way back when, could you order bundts on it? I bought the car with 4 steel wheels on it, I know there is a 15 inch bundt, but are there a lot of different width bundt options? They all seem the same in the yards to me, but i never measured them
