There's a common misconception that PUPs and A-frames suffer from the same "China bomb" syndrome that the big boys do. We don't, even though we have the same cheap Chinese tires as OEM equipment. Very rare is the tale of blowouts among PUPs and Aframes with tires less than 6 years old - or at least I don't see them like I do for the big boys.

I suspect some of the reasons for that is
  • we are talking single axles for the most part. Not nearly the squirming in corners.
  • in the smaller sizes, the tires have more margin in their construction
  • there's not as much profit to be gained by putting absolute minimum capacity tires on a single axle with smaller price differences between one tire size and the next. Hence, the OEM tires supplied tend to have more reserve capacity at the small end of the RV spectrum.
  • it's harder to cram as much stuff into a PUP or Aframe due to its fold-down nature. Again, makes it easier to avoid overloading the tires.
In my specific case, I knowingly exceeded the 65 mph tire limit for a 20 mile stretch of interstate to real-life test vehicle and tow handling with the Equal-i-zer hitch. I had already driven 30 miles at 65 and below. I normally set the cruise control at 65 (actual 63 mph) on the interstate. I do exceed 65 occasionally to pass a slow-moving truck. Non-interstate is marked 65 and below in Colorado.


Since my Aframe is kept in the garage where I have an air compressor, tire pressures on TV and Aframe are always checked before wheeling the camper out and hooking up.

Even when the camper is fully loaded with our stuff (we are pretty minimalist) and a full water tank, the Aframe tires are at less than 80% capacity and inflated to full rated air pressure. I feel pretty safe with the OEM 14" LR C Trail Express tires to date.

I had similar experiences with PUPs and OEM tires in the past - I never wore them out or even suffered a single flat. The tires eventually aged out and needed replacement for sidewall crazing and cracking after about 7-8 years when stored outside (same is true of boat trailer tires).

FWIW, there are now trailer tires available with higher speed ratings in certain sizes.

We've had three canvas popups and a hybrid. Our first had a 8' box, and it towed straight as an arrow...never a sway. Our next two had 12' boxes, and both needed sway control. The hybrid needed WDH and sway control.

Our A frame tows better than anything we've had. With the wheels moved as far back as they are by the manufacturer, and with our keeping the weight load balanced to keep the weight forward but not exceeding tongue weight, it's towing without even a wiggle. I was fully ready to invest in sway control, but the camper talked me out of it.

Like others have said. Load it with whatever you'll be hauling for outings and take it for a test drive. You'll then be making an educated decision.

I know it's obvious to some, but just remember when loading that your camper is a fulcrum. The more weight you add behind the axle the more you lighten the tongue...and vice versa. Adjust your load accordingly so that you're not lightening the weight on the tongue with a bunch of weight behind the axle, or you're not overloading the weight on the tongue with too much weight loaded in front of the axle.

I hope that helps.

My A122BH also tows beautifully without any sway control.

I think having the deck up front, the wheels pretty far back, and some weight on the tongue does the trick!

No sway, tows wonderfully. Purchased a Sherline tongue scale to be aware of the varying weight configurations I put on the toydeck and tongue. It's a useful tool, no more guesswork.

I have had no problem with my A194HW either, I read the manuals and they state to use a anti sway bar if you are towing above 3000 lbs and my unit is rated at 2400 lbs and even with water and propane and gear I have a 600 lbs buffer.

Only if your water, propane and gear weight nothing. 3000-2400=600 - water, propane, gear=600?

600# cushion for water, propane, gear. Right?

Lets go thru the math for you, Water 26 gal X 8 lbs = 208 lbs, Propane container each weight 17 lbs X 2 = 34 lbs filled with 4.5 lbs each of propane = 9 lbs x 8.2 lbs = 73.80 lbs

so, 208+34+73.8 = 315.80 which leaves 284.20 left for other gear.

I was just calling your attention to "3000 lbs and my unit is rated at 2400 lbs and even with water and propane and gear I have a 600 lbs buffer."

I know you have to subtract the wt of everything from the 600#, but that's not what your post said.

incorrect ...

of the the two past tent trailers that i have owned ... there has been both major issues with the tires ... first issue was tread separation ... on tires that were above 4 yrs old ... and the 2nd issue was again tread separation and chunk rubber loss from our next tires ....

im not one of theses dudes that prepare for everything ... but tire blowouts, and isssues are a large issue when towing something that are 1.5 tons .
