I did some research on your spindles because I was not able to find anything on our site, and it turns out your 1 3/8" spindles are obsolete and replacement parts are no longer available.

With that being said, I recommend changing out your spindles for the current size spindles. This is going to be very useful when finding replacement parts in the future or in the event of a breakdown.

For a 3,500-lbs axle you can use the #84 E-Z Lube Spindle w/ Brake Flange # TRU74FR, with the Easy Grease Trailer Idler Hub Assembly # AKIHUB-545-35-EZ-K, Easy Grease Trailer Hub and Drum Assembly # AKHD-545-35-EZ-K & the Electric Trailer Brake Kit # AKEBRK-35-SA.

Or

If you have 5,200-lbs axles you can use the #42 E-Z Lube Spindle # TRU37FR, with the Dexter Trailer Idler Hub Assembly # 8-231-50UC1, the Easy Grease Trailer Hub and Drum Assembly # AKHD-655-6-EZ-K, and the Electric Trailer Brake Kit # AKEBRK-7-SA.

The 5.30-12 tires, being wider, are going to make more contact with the road. This means that the noise, and heat build up will be higher than a 4.80-12 tire but the rolling resistance will actually be less because the tire is larger diameter. The…

Your math is correct in your trailer weight load example. If a fully-loaded tandem axle trailer weighs 4000-lbs then each of the 4 tires will bear 1/4th of that load, or 1000-lbs. In this case a tire rated for 1300-lbs would provide a good safety…
