Another story in the long history I have had with the car. After organizing a drive down in the Bay Area , CA, I was driving back over the Bay Bridge and found some debris in the road. I just side swiped it enough with the rim to take a chunk off the lip and of course cause the loss of air pressure. I was able to limp across the entire Bay Bridge as it happened right as I entered on the San Francisco side heading east. I have no clue how I survived not getting rear-ended. At the time, I did not know you could fix rims so I ordered a new CSL rim. It was not until recently in the last few years I found out you could repair rims. I have had the damaged rim fixed along with another front rim and a rear rim. Joys of driving on crappy California roads. At any rate now I have a “spare” tire in case I need it.
