Back May 2015, I had a set of 5 (including spare) 205/70/14 Carlisle Radial Trail RHs installed on my trailer. The lake I frequent is around 10miles round-trip. Add a couple of adventures to further lakes, I'd guestimate that I've probably put less than 3K miles on them altogether. It's been a trouble free 5+ years. My boat is stored indoors in my garage so the tires don't see the sun all day long, but they have been bearing the weight of the boat the entire time. I'm concerned if I should replace them next spring. I've read that tires should be replaced at least every 5 years regardless of miles. Any insight or suggestions should be appreciated.
