tire question

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.

    Please share with us how long ago this was...truthfully....

  • New tires are in your future......

    Now while it is convenient, easy to do
    OR
    While you are on your trip.......along side of roadway with damage to side of trailer

    Trailer tires age out......rarely wear out.
    5-7 yrs. is the typical time frame.
    Usually sooner when they are Carlisle especially 'D' rated. Bet they are just load rated for what your trailer axles are.
    Step up to a 'E' rated LT tire.
  • I would take them down to the tire dealer - have them dismount and inspect the tires. Risk assessment isn't exact and everyone has a different sized wallet.
  • 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.

    Time to replace even if the tread looks brand new. JMHO.
  • I'm thinking you should be putting on new tires sooner than later. 6 years is a long life for RV tires
  • The mileage is not the issue... Its the steel cords inside.. sitting in the same position most of the 6 years . . If it were me , I would be replacing them ASAP . . .While your at it , go up from a D to an E or maybe a G . .piece of mind
