Can Different Load Range Tires be Used on Tandem Axle Trailer

Question

Question:

I have a dual axle bass boat trailer rated for 5000 pounds. My front axel tires were worn so I replaced with tires requiring max 65 psi. My rear tires are same size but rated max 50psi and still in good shape . Is this an issue ?

Expert Reply:

Most likely the PSI difference between your axles is that you have a higher Load Range tire on the front axle now than what you have on the rear axle. Ideally you are running the same Load Range on all wheels of your trailer but in your situation you should be fine. Just be sure you run the max PSI for all tires listed on them at all times and you'll be good.

Answer 1

Although they are similar in width, the 235/85R16 size tires are going to be almost an entire inch larger in diameter than the 235/80R16 size tires. This means that your trailer won't be completely level while you are towing and your tires…

For a tandem axle trailer rated for 7000 lbs, you can use either a Load Range C or D tire. Each axle will be rated for 3500 lbs so you need a tire that will carry 1/2 that capacity. That would make your minimum load range before limiting your system…

It is okay to have different load range tires on each axle of a tandem axle trailer on a temporary basis but I do not recommend using the trailer in this configuration in the long term. Also, it is never a good idea to mix tires of different sizes.…

Answer 8

The last two number in a trailer size is the diameter wheel that it was designed to fit. This basically is only number where there is no leeway on fitting it to different sizes. So since you currently have the size ST205/75R14 that means you have to…

Having different size tires on your trailer can cause a couple of different issues. The first one being that they have different weight capacities. Your 4.8-12 ranges from 785 lbs at 60 psi to 990 lbs at 90 psi whereas your 5.3-12 ranges from 840 lbs…

Answer 11

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…

Answer 12

So long as you have the clearance to fit the larger tire in your wheel well and if you have a tandem axle trailer, enough clearance (about 2") between the tires then you can absolutely use the larger tire. A 235/85R16 tire is 9/10" larger…
