4700lb V12's are prime offenders with flat spotting. They were originally coming thru with V,Z-rated Michelins & Pirellis. They were replacing them with H-rated tires and affixing a 130mph speed limit sticker on the cluster for the early ones. I've seen the same problem as recent as 2004 SL 55 while I was still there with P-Zero's.
