Can Size 235/80R16 and Size 235/85R16 Tires be Used on a Tandem Axle Dump Trailer

Question

Question:

I have a tandem axle dump trailer it has 235 80/16’s on it. I have to replace two tires and was thinking about going to a 235/85/16 so that I could go to a higher load rating if I put two of those on one axle and have the 235/80/16 on the other axle will that cause any issues?

Yes, using two different tire sizes, like the 235/80R16 Provider # TTWTRTM2358016E and the 235/85R16 Provider # TTWPRG235R16, will cause issues for your dump trailer.

The larger size tire will be just about 1 inch taller which will result in uneven wear on your tires. It will also cause your suspension to sit at a different angle than it was supposed to and could cause uneven wear there.

You will want to stick with the same size tire for both axles. If you decide to get a bigger tire with a higher load rating just be sure to keep in mind that you least rated component will be your weight limiting factor. If your trailer is rated for under what your tires can already carry then upgrading your tires will not allow you to always increase your weight capacity.

In order to determine the torque rating for the lug nuts on your trailer you will need to know check out the chart I attached that shows all of the torque specs for all the trailer lugs available based on stud size, wheel material and wheel size.

Answer 3

The lug nut torque will depend of the diameter of your wheel studs and the construction of your wheels. • For a steel wheel and a 1/2 inch stud, torque the lug nut to 90-120 foot lbs • For a steel wheel and a 9/16 inch stud, torque to 120-140 foot…

I spoke with one of the engineers at HWT and he told me that the psi rating for an HWT wheel and tire assembly is only limited by the valve stem and tire. If your current wheels or new wheels have a psi rating under 110 psi, it is okay to use tires…

Answer 7

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…

Unless otherwise stated on the wheel itself, wheels themselves will be able to withstand the psi rating of any tire that is confirmed to fit it. The piece that you will want to look at is the valve stem. If you have a rubber valve stem then the…

Answer 10

I checked out the aluminum wheels we offer to see if there were large variances concerning tire pressure. For wheels that have a 6 on 5-1/2 bolt pattern, the psi rating was either 80 or 85. For wheels that had an 8 on 6-1/2 bolt pattern the psi…
