sorry, another tire question

Planning ahead to replace tires on tt next season and doing my homework. Seems like Maxxis will be the tire we go with. Our current tires are 225 75r15 D rated, but in checking our wheels it appears they are rated for 2830 lb. tire, this seems to correspond with an E rated tire. Would the upgrade from from a D to an E serve any benefit- better tire? As always, thanks to you all!

Look on the back side of your rim for a load rating. My rims have a 2830lb load rating which corresponds to E rated tires, even though the 5'er came with D rated tires. You may be able to put E's on if the load rating is there.

I replaced C rated tires with Maxxis E and ran them 15,000 miles with zero problems.

Replaced D tires on current trailer with E rated Towmax STR's, 2,000 miles and so far no problems.

Thanks for all the wisdom! I guess we will be going with the D rated Maxxis at this point.

The benefits of a E tire over a 65 psi D tire comes at 80 psi. Many 15" rims are not rated for 80 psi so as long as your OEM D tire has some reserve capacity it will serve you better in the long run.
Trailers can be easily over tired unlike a truck so bigger tires on a trailer isn't always better......... past a certain point.

Doubt you'll notice any difference other than an infinitesimal decrease in fuel mileage (no you won't be able to notice that). As long as your D rated tires have sufficient load carrying ability to handle your axle rating you gain nothing in going larger.

If some is good and more is better, then too much should be just enough. JMHO

The E is a better tire, the side wall is stronger LT tire side walls have more side to side play and a higher RR than the trailer tires.

Wouldn't we need to upgrade rims (Dexstar 15x6 jj) to use LT tires?

My Maxxis have served me so well that I will not look further. I'v even abused them with higher speeds (70) and no problems.
I feel like if you already have tons of capacity then you don't need anything else.
JMHO - YMMV!

Thanks ScottG, don't really need the extra weight rating but me being new to this figure more is always better! I think the D's are 8 ply and the E's are 10 ply, not sure if that's even meaningful.

Only if you need the extra margin. Myself, I have about 1000# excess capacity per tire with the D's so I didn't bother with E's. (I have 2 tons of CCC)
Maxxis rocks though - lots of tire problems before and none since getting them.
