Question:

I have a 32 foot flatbed with 3 axels. we are registered for 36,000 lbs. The wheels we have are rated for 3750 lbs and they are cracking like crazy. Do you cary wheels with a higher rating?

All available 16-inch trailer wheels with the 6-on-5-1/2 bolt pattern, such as Dexstar # AM20741 that you referenced, can be seen on the link provided. Most of these wheels are rated for 3050-lbs at 90-psi pressure.

Part # AM22657 from Americana is rated for 3200-lbs at 80-psi; parts # AM22658HWTB and # AM22658HWT are rated for 3580-lbs at 80-psi, which is the highest rating we offer. The valve stem used can also affect overall pressure.

If your trailer itself is rated for 36000-lbs gross weight and if it has 6 wheels total on its three axles, then each of the six wheels would have to handle about 6000-lbs. You may need to switch to industrial-grade wheels for this kind of weight rating, which we do not offer.

In any system, including the various components that make up a trailer (frame, axles, hubs, wheels, tires) you must stay within the capacity of the lowest-rated component.
