We do have complete axle assemblies and also offer more customizable kits. For your 5x8 utility trailer I will give you a couple recommendations for you to consider. It will basically come down to how large of tire will fit your wheel wells. Both of these axles share a spring width of 58" from side to side at center of the leaf spring locator pin, and hub face of 72" wide. If you have a different measurement please let me know.

The Dexter Trailer Axle # 20545I-EZ-72-15 is an EZ lube axle kit that includes a 5 on 4-1/2" hub pattern for 13"-15" wheels. The axle is rated for 2,000lbs. This may be higher than the previous axle but I recommend checking with the GVWR sticker that your trailer has on the front drivers side to confirm the correct weight rating. I recommend the Provider ST175/80R13 Wheel and Tire Combo # TA43RR as a good starting point to see the dimensions that your end tire might be. It has a width of 6.97" and diameter of 24.02"

The Dexter Trailer Axle # 20440I-EZ-72 has the same weight rating and EZ lube spindles. But it has a 4 on 4" pattern for 10"-13" wheels. For this bolt pattern the Kenda Karrier S-Trail ST145/R12 Combo # AM35351DX will give you a width of 5.7" and diameter of 21.3".

The U-Bolt Kit # APUBR-10 will connect the axle to your current leaf springs.

If any of the measurements are different from what you have or will require please let me know and I will give you my recommendation based on what you have.

The two sizes you mentioned are pretty similar and fit many of the same 15 inch wheels. The 205/75-15 fits rim widths of 5 inch to 6-1/2 inch whereas the 225/75-15 fits widths that are 5 inch to 6 inch. The 205 is 27.1 inches tall and the 225 is 28.4…

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…

From my research on the Harbor Freight 4x8 folding trailer uses 4.80-12 tires on a 12 inch wheel for the 1195 lb capacity trailer and a 5.30-12 for the 1720 lbs capacity trailer. It is a good idea to check your existing tires to see which size they…
