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. Tyrone Big Pine Key, FL 87 GL Syncro 85 Westy etc......
