I've been putting a lot of thought into this and don't really have a real good answer. Basically, I didn't like the idea of a ST tire running at 110 psi and going up higher than that while running down the road. Just seemed like a lot.

The bit of reading that I did - I liked the heavier construction of a commercial tire. It is designed to run down the highway and since it's still a trailer tire, it can take the twisting forces of backing into spots.

The other pros were:
- the super extra carrying capacity
- the slightly smaller size
- the higher speed rating

Had a long talk with the Flagstaff folks about upgrading my torsion axles after losing one followed shortly by the now overloaded one.

The upshot is that too heavy an axle for the supported weight will transmit road shocks directly to the camper's frame and contents. He said the same was true of tires. While going up a single load rating should not cause excessive stress to the frame and components, going overboard will eventually cause wall cracks, loose or falling cabinets, and frame damage.

Use caution and common sense when upgrading OEM parts.
Just the messenger...

Herk Thanks that is very good information to pass on. To me as you increase things to much, you will create a different problem. Our trailers are purposely engineered. There is only so much one can do, such as moving up from "C" tires to "D" rated for your load and to get a little more capacity on the tire load as an example. I really don't know what the safe capacity of your GW should be. If you can explain that to me a little I would really appreciate it. There is a point that you will do more damage then good if you don't change everything involved, when trying to over engineer a trailer. Would I go to an "E"rated tire over a "D" from "C" rated my thinking is no WHY? Thanks for your post and explanation. look forward to your opinion, On common upgrades without going crazy, that would really hurt more then help.

Glenn, I am not sure what you meant by "GW" so I can't address that.

What I can say is the effect known as "The Rule of Unintended Consequences" applies when you think you are going to make something "better" by changing something. There are always consequences to change of any kind. Some consequences are predictable and mitigations can be "engineered" into your solution; but the ones that keep engineers up at night are the unintended consequences that only become apparent AFTER you have passed the point of no return.

A perfect example was the Apollo space capsule where the LEM was designed by one aerospace company and the Command module by a different one. The Command Module used a CO2 scrubber with square connections and the LEM used a CO2 scrubber with round connections.

The consequence of that decision did not become apparent until Apollo 13 when the 3 astronauts needed to use the LEM's system as a "lifeboat" and scrubbers from the Command Module were needed in the LEM to keep the guys from suffocating.

This is the actual hack that saved the astronauts of the Apollo XIII

Putting an axle significantly stiffer than called for by the initial design (whether on your camper or your truck), will not make your camper or truck CAPABLE of "carrying" more than its initial design without consequences (some seen and others unforeseen) to other systems that make up your vehicle.

Good info, Lou. These forums are definitely "buyer beware" and there's no one answer that fits everyone.

What tires are you changing from and to? I thought you just put new tires on last year?

The last tires went on in September 2013. They were 16" Maxxis m8008. I've sized up to 17.5" Conntinental HTL2.

Sorry, haven't read the whole thread, did you have a blowout(s) or they just wore out?

No worries. Neither, really. Well, I did get a flat in one but that was after I had pretty well decided on this upgrade.

The longest story shortest- I am running really heavy. I got individual wheel weights done and found that I was very close on maximum capacity for 2 of the tires (within 20 lbs.) and over capacity on one tire (by 80 lbs.). I wanted more carrying capacity, but the spacing between the tires limited my options.

So I guess you could have bought a bigger trailer or beefed up what you had.

And it's apparent that you chose the latter. And have invested some money into it.

I'm not saying it's wrong or right because I'm no expert in figuring weights and such. I do know when my truck struggles with pulling my TT. I'd love a bigger truck but no more than we go, I just baby it on the hwy as I never go over 60 mph.

I understand what Herk was saying though about where the stresses may go when you tweak the dynamics of the OEM suspension. Just keep a close eye on things. Hopefully, if it does happen, you'll know what to look for.

After you get everything sorted out and get a few miles down the road, keep us all posted on how things are going.
