Got a flat tire on one of the inner duallys, road service found sidewall pin hole leak and can’t be repaired,tires are 5 yrs old and about 40K miles. They are hankook AH 12 16 ply. Newer hankook are AH 37 18 ply. Thinking about repaceing the two front with the AH 37 but am worried about them being 18 ply and making a hard ride. Was going to use one of the fronts to replace the damaged tire in the rear so that tread wear would be the same. Advice needed.

Bite the bullet. Buy new ones..

You can start paying to start swapping tires around but you might lose another one in a month.

Sounds like a good plan. Put the new matched rubber on the front where the possibility of a tire problem is most impactful. You also are matching the rears to some extent. You don't really want to run tires of significantly different diameter on the same side of a dually.

If you know the coach weight, you may be able to run a slightly lower pressure for a given load with the increase in plies. The lower pressure would possibly mitigate an increase in stiffness with the extra two plies.

If you follow the manufacturer's weight chart, you will see that they give a certain PSI to handle the axle weight and it is always the same PSI regardless of the number of plies or rating. An F or a G rated tire would need the exact same PSI to carry the same weight. The only difference is that the G tire can carry more weight, if you increase the air pressure. Inflate the new tires to the proper PSI according to the actual weight on your front axle and you will not be able to tell any difference in the ride.

If the tires are 5 years old replace them all.

Five year old tires are about aged out. They never last until the treads wear out unless they are constantly driven like an eighteen wheeler or are bad out of alignment.

X2 and if you’ve put all the miles on the rear tires, properly inflated and used often, I would not replace the rear tires at 5 years. I was very happy with the 6 Hankooks I put on the rear of my Dynasty...not a single crack in the sidewalls at 6 years.


This post is my opinion (free advice). It is not intended to influence anyone's judgment nor do I advocate anyone do what I propose.
