Radial Trailer Tire to Replace 5.30-12 Recommendation

Question

Question:

I have an old pop up camper with 5.30-12 tires. I want to upgrade them to the same size but radial, and I was looking at item AM31202 on your site. Would these be the equivalent for a swap out? I will double check the bolt pattern before purchase. Thanks!

In the 5.30-12 size we only have bias ply options. For a similar size that would work that is radial we have the ST145R12 like the part # AM10140 which would work really well. This will fit the same wheel size.

Answer 1

On a towing setup you are always limited by the lowest rated component as the overall towing capacity since that is the weakest point. When it comes to trailer tires you always want to have them inflated to their max psi when cold. Not only do you…

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…

If you are questioning the quality of the tires or their ability to hold up I recommend just replacing the tires. Defiantly be sure to check the age of the tires to ensure they are not too old. I typically recommend once a tire is 5 years old to go…

I did some calculations on the tire sizes and found that the difference between the 175/80R13 and the 155/80R13 is pretty small. The 175/80 is 24 inches inches tall whereas the 155/80 is 22.7 inches tall for a difference of 1.3 inches total, but that…

The 155Rx13 tire is an older size that's not used much at all anymore, which is why you're having so much trouble finding an exact replacement. Because of this your best option is to replace the tires with the closest current/modern trailer…

Answer 6

A 5.30 X 12C tire is going to be your best replacement. If you need the 4 on 4 inch bolt pattern #AM30780 is a good option, or #AM30820 for the 5 on 4-1/2 inch bolt pattern. These both have the wheel and tire included, which you'll need, since…

To get you to a higher speed rating of 81 mph I would go with the Kenda Karrier ST145/r12 par #AM31202 which is only a little bigger and has the higher speed rating you are wanting. It has the correct 5 lug wheel bolt pattern as well.

Yes, the Kenda Karrier S-Trail ST145/R12 Radial Trailer Tire #AM10140 referenced in your question will fit the same 12 inch wheel with a 4 inch width that your existing 4.80-12 size tires are mounted to. Just note that the ST145/R12 tire will be…

Answer 9

Both the trailer wheel and tires #AM31202 and #AM31199DX have an 81 mph speed rating as you are correct they both use the same tire.

Answer 10

It can be a flat end as long as the flat part is long enough that it can reach past the wet bolt just fine. For your application it looks like the 4-Leaf Slipper Spring w/ Radius End for 2,000-lb Trailer Axles #e69SR is the closest that we have as…

I would be happy to help you find the correct replacement slipper leaf springs for your dual jet ski trailer, but you will need to identify the axle rating of your axle and the width of your slipper spring. To find the axle rating you will want to…

Answer 12

You have what's called a slipper spring. Which the closest matching spring we have would be the part #SP-178275 which is for a 1,000 lb trailer axle like what a jet ski trailer would normally have and has a length of 24-5/8 inches from the front…
