I don't see what size tire or mh you have. We put Michelins on ours, I think they are 285x75x22 Michelin RV Steer axle tires. They have a center groove to help tracking and a decoupling groove on each side of tire.
I'm not sure of the air pressure in them at the moment. Where we store it has a chart they consult.
We had Goodyear G670s on it when we bought it. They were stiff and we had wear problems on front axle position.
725.00 indicates to me a larger tire than ours. Consult Loves and use the FMCA Michelin program. I think we paid around 500.00 or less. We didn't get them from Loves regretfully because of time element an paid for mountign and road force balancing tht cost uss twice as much as Loves.
