Just make a new one, Map site then click on "My Preferences" in the grey bar near the top, and re-do your signature. :)

So... After all your good advice and suggestions :p (and a little help from a few other sources) yesterday I mounted four new Maxxis M8008 225/75/15 D tires on my trailer complete with steel valve stems and pumped up to a whoping 65 psi as recommended and balanced... I brought the tires to the shop on my utility trailer because the camper is still in winter mode (how sad is that) being that they didn't have to "install" the tires and the shop gave me a discount. Total cost out the door $534.60

Tomorrow I'm on my way to purchase one of my two new Honda eu2000is generators... Getting ready to get ready for NASCAR camping, first stop MARTINSVILLE!!!

After tax time rolls on by and my dear old Uncle Sam gets his pay for the year a new Tow Vehicle is a commin'

I run E rated tires on my 2600# rims and increase pressure above 65 psi and thereby do gain some reserve. It is perfectly acceptable to run less than the max on a tire but it affects carrying capacity. Since I can gain no further advantage above 72 psi (due to the wheel limits) that is what I run them at. My wheels give no max psi but being rated for only 2600# would indicate they may not be suitable to run at the max 80psi allowable in the E rated tire. I gain capacity over the D rated tire and max the capacity of my wheels. It is not rocket science in the end.

Apparently there isn't any benefit running E rated tires at 65#. I don't see any reason to.

They achieve their max weight rating at 80#, and that's what I air them to.

MAXXIS!!!!!! That's all I have to say.....

The E tire has a thicker/heavier carcass which will generate more heat when with the pressure derated to 65 psi. After ruining two sets on two separate enclosed/equipment trailers at the same time I started taking my truck tire dealers advice and stopped running high pressure tires at low pressures.

Tireman9 (Roger Marble) has some good advise on this issue;
rvtiresafety.com

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.

My worthless opinion is that I would rather have way too much tire than not quite enough. A tire with a lot of reserve capacity will likely have less heat buildup and less chance of failing.

Maxxis was good to me when we had 15" Tires.
