Sailun tires versus Michelin

What do you think?

IMO I would rethink your trailer tire needs as its never the best idea to over tire a trailer in that excess. Sure we can over tire our trucks but tires on a trailer operated in a much more severe environment.

Watch a tire on a trailer at max pressures as it side scrubs while turning a corner. Now derate the tire with 30-50 percent less pressure and make the same corner. The tire lost its shape and is more suspect for internal damage (belt separation). Rolling over a curb or over a pot hole under inflated by that much the rim can easily cut/bruise the sidewall.

The question of load capacity and Load Range gets asked a lot, so it seems to be a bit of a stumbling block for a number of RV owners. Here is an example:
"I need to replace the ST235/75R15 tires on my trailer. Currently have load range C tires which is sufficient for the maximum trailer weight when inflated to 50psi but allows almost no safety margin. I want to change to either load range D or E tires. My rims are only rated for 65 psi so if I went to the load range E tires I would only be able to inflate them to 65 psi. My question is this. Is there any advantage to a load range E tire used at 65 psi vs a load range D tire at 65 psi?"

Now just because he is asking about a 15" trailer application and considering a change from LR-C to LR-D it does not mean the general answer does not apply to others, even if they are considering a change from LR-G to LR-H on a Goodyear 295/75R22.5 Class-A tire.

The answer to the question is;
He will gain a safety margin if he increases his inflation to 65psi with LR-D but if he stays at 65psi there is nothing further gained by going to LR-E as there is no difference in the capacity at 65psi.
