Per,

I have the Cooper SRM II Radial LT size 195/R14C tires on my 87 Syncro. And
just about three weeks ago, I was driving down the llllooonnnnggggg road that
goes towards the area where we live here in the FL. Keys, when I saw in the
distance an officer pulled over as they usually do when doing their radar
thing. So I pulled up to him and asked him to clock me at 30 mph (the posted
speed limit) and he said, "sure". When all was done, he told me That I was
doing 29 mph when I thought I was doing 30 mph. Later, when I happened upon one
of those info-radar gizmoes you mentioned, I found that at what I thought was
40 mph I was really doing 38 mph.
