I read this forum frequently and RV tires are a common topic. We all know that ST tires are generally not good and those of you who have RVs with 16" or larger wheels are changing to LT tires for better performance. I was thinking about my own RV tires (15" five hole wheel) and the fact that I don't have much choice without making a substantial investment in different axils and wheels. As I was thinking about my current tires, it occurred to me that when monitoring trailer tires, there are 5 tires on a trailer that need to be considered, not just 4. If your tires need to time out (over 7 years old) so is your spare. As I think about it, my spare is the original tire on a 1996 RV. That's 18 yrs and 2.5 times the tires have been replaced. How many of us remember the spare when we purchase new tires. I venture that we are lucky if we ck the air pressure. My spare is covered and looks good. Has about 50 miles on it, but it still is an 18 yr old tire. Might not last long if I had to use it for very many miles. That got me to thinking, does anyone rotate their RV tires like we do our vehicle tires? I don't recall anyone on this forum talking about that. If we were to rotate the tires and include the spare in the rotation so that when it is time to replace the tires, the spare has equal use and we are not throwing away a new unused tire that is too old and unsafe. On the other hand, maybe a new unused spare is batter insurance when we really need it. Either way, the spare is not immune to the march of time just like the other four tires. Just a thought.
