RE: [Chevelle-List] P275/40ZR17

Nice Job Herb. I didn't know we could post pictures here. Some list servers don't allow it because it can blow up digests and some people have text-only mail readers.   I guess I finally know what those numbers mean. For some bizarre reason, I always thought the 40, 50, 60, etc. was the width and the 225 or whatever referred to the height. I guess it always seemed to me that the lower the number  (40, 50, 60, etc.) the wider the tire. My Nova came w/ 78's and I put 60s on it, which were definitely wider. I'll get it right some day. It's bizarre to me that these numbers are a mix of US and metric, but it's certainly not the most bizarre thing I've ever heard of.   John Nasta
