IMO using the LRE tire inflated to 65 PSI to achieve a LRD rating, provides you with nothing more than any other LRD tire.

Rims are certified by SAE to a load capacity and an inflation pressure capacity. Take a look at the specs on the rims in the reference below as an example.

When in doubt, call or email the rim manufacturer for conformation.

The OP was asking about using an LRE tire vs LRD but being limited to 65 psi if the wheels wouldn't support 80 psi. I agree that the LRE would be the same as an LRD at the 65 psi, but, the LRE is rated 10 ply and the LRD is rated 8 ply. Does that not equate to a "stouter" tire even when running 65 psi? Plus, he was looking at going to a new, American made tire so in my mind he would be upgrading from where he is and the LRE would be an upgrade over the LRD.....wrong?
