yes...yes I do. I had to run a 10" bias ply spare from Baker to Newport Beach (~200 miles) when my Honda AN600 got a flat. About 10 miles into the trip back on the 1971 era spare (This was 1985!) I took it off the front and put it on the back as it was near impossible to keep in 1 lane. After that the back was squirely the entire way home. Some old Centerlines still say 'Bias ply only' on the center register. Later Centerlines were made with a heavier bead for radials.
