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
Unless you don't mind blowouts and like trailer damage, REPLACE the tires now. Do not wait until to HAVE TO.
It will be much safer (for you, your family, and the rest of us on the highways) and less costly. Upgrade tire size, get better tires, replace valve stems with stainless steel stems, and balance the tires.
Of course, if you like to gamble, don't do any of the above.
