Trailer tires are the last tires anyone thinks of. Your wheeler gets the best tires you can afford. You tow rig and/or daily driver gets the next best tires you can bring home. But your trailer is the poor dog that has to fight for any love. All you require of the trailer is that it not break and not cost you much money. After every off-road event we attended we hear about trailer issues from our friends who were there. Bearing and axle failure is one thing, but tire blowouts are the biggest culprit. We have tried lots of different options for trailer tire duty over the year, and we are really excited about the latest rubber under our big red hauler from Hartland.
We get most of our local tire work done at the America’s Tire/Discount Tire in our town. When we asked the company about a beefy trailer tire we wouldn’t have to worry about whether we are scrubbing curbs in town, haulin’ at high speed on the interstate, or bouncing down dirt and gravel to the trailhead, the company recommended these ST 235/85R16s with a G load rating! We had them swapped on in under an hour and were so proud of our poor ignored workhorse that we actually washed the big hauler when we got home.
We like our trailers to be tough and simple as an anvil. We have gone to steel wheels for simplicity and easy access to the lug nuts. We have a steel deck so there is no need to refinish wood that sits out in the sun year-round. And we wanted a tire we could ignore save for checking the air pressure before long trips. (Honestly, we need to get tire pressure monitors for this thing.) The guys at our local America’s Tire mounted and balanced the tires fast. We always balance out trailer tires because we fully expect it will be running down the highway at uppermost legal speeds to get us to the trail on time.
Check out that rad tread pattern! Yeah, it’s about as boring as a board, but remember we want this thing to follow the straight and narrow behind out tow rig, and boring straight tread will do just that. We have tried aggressive knobby trailer tires in the past, but none of that makes much sense. The tires aren’t driving; they are dragging. The less they hold you back and the longer they last the better. And they are regroovable for even longer life.
Here is the meat and potatoes of these G-load-range tires that can take the abuse. They are an all-steel carcass radial with one ply of steel on the sidewall and four plies of steel on the tread. The Hartlands are rated at 110 psi and 4,080 pounds per tire. Even with our steel-deck Carson trailer and heaviest fullsize wheeling rig, we are nowhere near that much weight. The Hartland trailer tires are exclusively sold at Discount Tire.
