How are you determining actual speed? GPS or road signs? Your tires are
the same diamter as the 215-70's Im using and my odometer still
over-reads by almost 4%. The original tires rotated 830 RPMiles.

Subject: Michelin XCA tires - highway RPMS

Someone was asking what the hiway RPMs were with the Michelin XCA
(205/75R14 LRD) tires that are a larger diameter than the MXTs. (I noted
that my speedometer now reads 3 mph slower than actual speed - my speedo
is labeled 805 on the bottom) According to the sidewall of the tire they
are rated at 2270lbs max load at 65psi.

America's Tire company SKU 35838  Price $109 ea.  Tires labeled "Made in
France"

Here are my ballpark observations of RPM at (corrected) speed. 1988
Vanagon Westfalia 2wd. Tires at about 50 psi. I could get more accurate
readings if anyone is dying for more presision. As they are, I'd say +-
1mph.

65mph = 3660
70mph = 3800
75mph = 4100
