Anyone else going through trailer tires this summer?

My 24' enclosed trailer loaded with stuff weighs close to 11,000 lbs. Can't believe mfr. sticker shows load range D tires.

People don’t understand that a big reason we have an enclosed trailer is because we take lots of backup supplies to the track. Nuts, bolts, oil, transmission fluid, carb parts, spare ignition, spare fuel pump, and the list goes on. Heck I carry two generators.
