Tires - Load Range D vs E

Checked my local tire stores and all of them only had load range E tires in stock

Yes, that is one reason I went with load range "E". Load range "D" little bit harder to find on the road.

Do you think it would make a difference in the ride

First trip for us with new load range "E's" that were aired up to 80psi, some stuff moved around more than normal. After watching temps on tires, we now run 68-72 psi. Seems better for us. And also had brass/steel valve stems installed. And wheel/rim is still within its spec's. Our trailer already had shocks.

Dreaming a little..would be nice if I could install air bags on trailer.

Of course every tire manufacture probably has its own load range chart. And I didn't bother to buy spare.
