You probably do not need to replace your wheels.
I don't know what brand Seri06 is so I am not looking at their website .
What the charts often say is : "1820 # at 50 psi "
What this means is you need to inflate to 50 psi to get the 1820 # rating .
That means that 45 psi does not get the maximum 1820 # rating .
Your best bet is to email the wheel manufacturer and ask them the exact specific question such as : " I want to install a load range D 225/70R15 tire on this Seri06 wheel and inflate it to 65 psi to utilize the maximum weight capacity of the tire . "
Many on this site have mistaken the charts to limit psi .
Further , CapriRacer has posted on this forum that he would consider inflation to 80 psi to get the most safety from a load range E tire even if a wheel is a 65 psi wheel .
The tire is the weakest link .
The wheel has been engineered to withstand high load and sideload weights and psi is a minor consideration to those engineering standards .
A wheel does not fail catastrophically due to psi .
The wheel can develop a hairline crack due to whatever abuse and will simply leak out the air .
That air loss may make the tire overheat and blow out .
But too much psi does not create the hairline crack .
A wheel does fail catastrophically due to curbing , high side loads , or other abuse .
