I have a set of Carlisle Class D tires on my 30 foot Fiverr. They are six years old with less than 2000 miles on them. I'm thinking they should be ok as long as there is no dry rot? Thanks, Mark
If you can get LT tires to fit your wheels you will be in much better shape. Switched to LTs 7 years ago and have had no tire issues. ST tires should be replaced every 3 years regardless of what they look like.
