I know people always complain about tire blow outs on these, but her I wonder Why? How do those things tow anyways with those dinky narrow tires? I'd imagine things would get a bit interesting in a heavy crosswind

A properly loaded travel trailer should be within the weight limit of OEM tires on a travel trailer. Most blow outs happen from under inflation, and curb hopping, as well as excess speed. Most travel trailer tires are rated for 65mph-at maximum inflation.

When was the last time you saw somebody check inflation before pulling out of a campground? How many times have you seen a rig going faster than 65mph?


With a properly adjusted weight-distributing hitch/anti sway device-sway should be kept under control except in extraordinary circumstances.


I have towed a travel trailer from the west to east coast-and all over the inter-mountain west and had never had a blow out-because I always check inflation pressure, never exceed 65mph-and replace tires at the first signs of cracking.

I've always wondered that too. I think they should either go big or go home.

One of our senior engineers is from a farming family and they are all over the Goodyear Endurance (US made) trailer tires for moving some serious kit … they have even modified fenders to max out the tire size with the axle rating …
On all boats I have ever bought - the factory tires become spares … ST tires = big problem with small solutions …

We take our horse trailer on the pretty rough back roads here and it has the smallish 15 inch tires/rims. Finally found some 10 ply trailer tires for it. Seems like the 15 inch trailer tires are scare in 10 ply. We had a run of flats with the old 8 plys and so far no problems with the higher rated 10 plys.

I’m in Minnesota and see snowmobile trailers a lot. Those have teeny tiny tires to make a larger flat bed. Crazy seeing people driving like 85 MPH towing those things. You do see quite a lot of them broken on the side of the road - especially when they get old.

my little trailer seems to be equipped with the exact opposite it has large tires considering it is only 6ft long 46 inches wide.
the stock tires are 205/75/15 it has a lot of ground clearance also.

For problems with tires and axles don't forget rusty bearings on boat trailers. Combine that with low inflation pressures and it's a good idea to keep clear of anyone towing a boat down the road. When a tire blows out or a wheel comes off you should consider not being there.

Our horse trailers have larger wheels and tires. Horses are a live load and a bit of extra safety margin on ratings is good. We usually carry 2 spares and a repair kit. Being stuck on the side of the road with a flat and 1 to 4 horses is no fun. We also inspect things on every trip. Having an accident with horses is even less fun than a flat tire.

I don't know that I've seen "tiny" tires on an RV trailer, but it certainly depends upon what brand/grade of rig you're speaking of. Some of the older, lighter pop-up trailers got those dinky squatted tires and they were poor to say the least.

My rig (Cherokee Wolf Pup) came with a tire/suspension package that is actually quite will suited; actually over sized if you ask me. My dry weight is around 4k, and my GVWR is 7k, and I have two 3500 pound axles with C rated ST205-75R15 tires. I just recently "upgraded" to "D" range this summer.


Many of today's upper end rigs have decent sized tires on them. But the cheaper you go in the market of RVs, they will cut costs everywhere they can, and that includes the running gear and tires.

Is this some sort of surprise?

The act of preventative maintenance, in and of itself, is FAR MORE important than brand/grade/base choices among lubes and filters.
- under maintaining something is akin to abuse/neglect; that can kill equipment by shortening the lifespan

Tire Blowout mostly happen to irresponsible owners:

1) outdated old tires, they expire/crack/loss integrity despite how few miles you run them
2) running tires low on air overheating them leading to blow outs
3) overloading tires
4) speeding with tires which overheats them
5) damaging tires by 2,3,4 of combination thereof
6) parking tires long term on less then optimal conditions (dirt, grass, gravel etc) instead of a 2x8

Some of that is true, but it's also due to cheap tires sourced from China. I personally had a blowout on one of my brand new Discount Tire branded Hartland trailer tires this fall. The tire had a whopping 1350 miles on it; was one of four brand new tires bought this summer. I was traveling 65 mph, in a light cool rain, on a smooth interstate. I had checked the tires the night before, in preparation of our return trip home that day. The tire that had a failure was a true, catastrophic separation and shredded itself in a matter of seconds. It was in the left, rear trailer tire position, when means the other three tires (LF truck tire, LR truck tire, LF trailer tire) all seemed to pass over the same ground prior to the LR tire did, before it blew out. And, they are "D" rated; good for 87mph and 2150 pound each. My trailer only weighs 5k total, which means ...
- the tire was no where close to max load capacity; probably was loaded to around 60% of capacity
- the tire was way under the rated max speed; 22 mph under it's advertised limit
- the tire was not over-heated due to environment; it was in the 50s and raining
- the tire likely did not get a puncture; the three tires in front if it didn't suffer any damage or malady
Nope - it failed because it was a poorly made, poor quality-control tire. Despite all the assurances of the guy who sold them to me.

In the future, I will ONLY buy tires made in the States for my trailers. Even though it costs more.
Goodyear finally decided to start making their trailer tires here in the States again.

I think the reason there are blowouts is because people never check the pressure then hop on the freeway and run 90.

That is not quite true many times the front tire will hit junk on the road and stand it up into the rear tire.. I suppose you could have had a loss of air pressure and catastrophic failure, but agreed its unknown and not likely I suppose.

I'm assuming you meant they are D-"8 ply" with N Speed rating.

That is actually quite decent for trailer tires..
I laugh everytime I see some redneck bro truck with a 12" drop hitch(because of massive truck lift) towing a uhaul at 85mph that has dont exceed 45mph on the fenders.
