I was looking at my OTT Service Tickets today and was reminded that Cooper Tire had a problem with valve stems (my Oliver is a 2022) -- they reimbursed the Owners after the stems were replaced (locally done). The service notes include OTT Service Dept's surprise and my dismay at the cost ($90 for the work done here locally in Lee County Florida); OTT Service Dept said it would normally only cost $10 to $25. Anyway, I had forgotten all about that issue with the Cooper tires.
Last week, after this forum discussion, I went to a reputable tire place to inquire about getting valve stems replaced (putting in metal where I have rubber)... I can't get my Oliver into their lot, and I'm not allowed to do the work where I store my Oliver, so it was going to require a Mobile Service, and I planned to take my Oliver to a large parking lot 2 blocks from the tire place. They quoted me $250 and when he saw the shock on my face, he explained that the metal valve stems cost $25 each (someone on the Forum just quoted $6 each) and he said he wasn't even charging me for the Mobile service! He offered to do it for $200. Needless to say, I will forgo that for now.
