Most have it right.

No car tires as they have too thin of a sidewall and will not carry the load, especially a radial.

Bias Ply TRAILER tires will handle the load but check the tire weight rating, you have a heavy rig.

Replace trailer tires every 3-4 years no matter how good they look.

If you blow one out replace the tire next to it at the same time as it has been overloaded.


Think about it, how many cars with 15" wheels weigh more than 3000 lbs empty. How many tires for cars do you think they make for 14,00 lb cars?

Been down this road.
