It doesn't look like the load rating would be sufficient since p-metric tires load ratings need to be derated for use on light trucks and vans.

Since the tire you have is p-metric, and governed by p-metric load formulas, the division of its load by 1.10 applies.

With your tires load rating of 1510 lbs divided by 1.10, the actual load rating for the tire would be 1373 lbs. in your application. I know that is less than the rear GVWR number for one tire of my van.

The Kumho Tire Engineer sent me this when I was shopping for tires:

The Tire and Rim Association is the governing body, in the USA, for tire designers and vehicle designers alike. They are supposed to adhere to the following T&RA rule:

""When a passenger tire is installed on a multi-purpose passenger vehicle, truck, bus, or trailer, the tires load rating shall be reduce by dividing by 1.10. The sum of this new reduced load rating of the tires fitted to the axle shall not be less than the gross axle weight rating of the axle system as specified on the vehicles certification label.""

"This is a built in safety factor to compensate for the "abuse" of overloading and off-road/secondary road conditions seen by these types of vehicles."

I would also question whether this tire has a high enough maximum inflation pressure and sidewall ply rating for your application. You should look for a 44 psi+ maximum pressure and a 6-ply rating.

Good Luck,

Tim
