Sent a PM on these about the load rating.
I have no idea what the load rating would be for the tires... but I'd hazard a bet they are rated similar to the Good Years you were talking about.
A question has been submitted to MH through their website since their phone line was busy when I tried to call. I havent heard back yet.
edit: just got a message from John @ MH. Per tire, the load rating is 992 pounds.
