Well, yes and no .....
The photo is for a 225 75R15 LRD (8 ply rated) tire with a load range of 2540@65PSI. If that is the only one that came up, it's the "little brother" of what most members are installing on 15" wheels.
Most discussions on the forum are related to the same brand/different size: 225 75R15 LRE (10 ply rated) with a load range of 2830@80PSI.
I believe your trailer has 6 lug wheels, but depending on your wheels (5 lug or 6 lug) you might want to consider upgrading from LRD to LRE tires. The cost is minimal to obtain the 1160 pounds of additional tire capacity.

As an example, the 225 75R15 LRE tires are available at WalMart for $87.15, about $50 less than the LRD tires at Discount tire.

Do your shopping wisely. DT will often match pricing with WalMart's prices.
