Great info here! I have to admit I am one of those TT owners who know little about the tires. I bought it new and only checked tire pressure a few times and never had a blow out or flat. It still has the original tires and last time I was at RV dealer they were amazed I they were still in decent shape. Mine weren't weathered but the service manager showed me the sidewalls were starting to bulge. The sales manager just replaced his same year TT tires the season before so unlike those here getting 3-5 years this was 2 years ago so that was at least 9 years of use. I store mines on dirt if that makes a difference and many times there are covered with mud so wondered did that help preserve them lol.
My trailer was retired that season so hasn't been on the road since, if it does it will only be after new tires. I feel better informed after reading this thread now know I need to do some more research on tires.
