ST235/80-16 Trailer Tire and Wheel Recommendation for a Toy Hauler Trailer

Question

Question:

I typically run HD truck tires on my trailers and this trailer is due for new tires. To go to an HD truck tire though I need a 16inch wheel and now looking at this site it looks like a good package deal.. What is the life expectancy of the tire listed on your site being the Kenda radial? The trailer tires are usually 3 years with a 55 MPH cap... And they are more susceptible to blowouts than truck tires. Years of personal experience here.. I have not had any experience with these radial trailer tires though and if they still have the same stats as a bias trailer tire Ill stick with the truck tire. Kenda ST235/80/R16 Load range E HWT aluminum wheel 6 on 5-1/2inch LR-E- black

So there is a lot going on here. First you should know that trailer tires are constructed differently than passenger vehicle tires. Trailer tires, with ST in front of the size, are built with a thicker sidewall to handle more vertical load whereas passenger vehicle tires are built for more lateral forces (because they have turning axles). This is why passenger vehicle tires should not be used on trailers.

The main reason trailer tires see more blowouts is because people under inflate the tires. Trailer tires should be inflated to the maximum psi indicated on the tire. If under inflated trailer tires generate excessive heat due to the thicker sidewall and that is what causes blowouts.

It is hard to pin down a specific life span for a trailer tire because it depends on how often the tires are used and, if not used frequently, how the trailer is stored or tires covered (or not covered).

Most trailer tires are now rated for 65 miles per hour but there are some that are rated higher. For example Taskmaster tire # TTWTRTM2358016E is rated for 81 miles per hour.

Radial tires are excellent for road travel. They track better and run cooler than bias ply tires. Bias ply tires work fine on pavement but excel more for off-road type applications (gravel/dirt).

Trailer tire failure is usually a result of excess heat, which can arise from a variety of potential causes. The first important factor to always consider is the inflation of your trailer tires. A tire that is under or over-inflated will build up…

A ST235/80R16 trailer tire measures 30.8 inches in diameter, and is 9.3 inches wide. These are large tires built for heavier loads, and you can choose either a load range E or load range G ST235/80R16 tire, depending on the capacity you need. I…

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 8

The difference between an load range C and load range D tire in the same size is the capacity and psi rating. The two tires will still have the same dimensions and fit on the same wheel. The D rated tire has a higher capacity. For a ST175/80D13 like…

Answer 9

You will have to go with a sliding hitch to allow the trailer to make tight turns. For a trailer 8 feet wide the only bed length that's going to allow 90 degree turns without a slider is a stationary hitch. That being said you have two options.…

Answer 10

Load range B trailer tires are going to have a lower capacity than C load range tires. Basically that, psi rating, and the ply rating are the only differences. A higher load range tire would last a little longer than lower load ranges of the same…

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

The three most common lug stud sizes for a trailer are 1/2"-20, 9/16"-18, and 5/8"-18. In order to make sure you get the correct lug nuts you need to measure the lug studs on the trailer now as we have no way to look this up for…
