Towing Sway

[H3LZSN1P3R]

I'll agree with that for the guy that tows A LOT (like you).

For the recreational/summer vaca type of tower, go max or near max psi and call a day.

I can agree with that, the avg person who is just going on a short trip with their camper likely wont see any extra wear on the tires center running max psi while towing.

Did I overlook your trailer weights? Pin weights? If you’re getting sway, you are doing something wrong.

As others said, definitely check your tire inflation and fill according to load charts. You likely don’t need to be anywhere near max inflation. I run 47 psi out of 80 max

I have sumo springs and I’m happy with them for loading the truck to GVWR and fighting squat on a “leveled” truck.

Thanks. I talked to Steve at Timbergrove this morning, and ordered a set of their airbags to put on the truck. If that isn’t enough, I will probably add a Thuren trackbar.

You will like those bags. Steve was great to talk to when I ordered mine. I did not do onboard air as it was more involved than I need for towing our 5er on the weekends.

As for the trailer sway, is the coach suspension in good shape? Tires aired up properly on that? How did you load it. Lightening up the pin weight isn’t always good. Now that you will have bags load the front up some and see if that helps.

While overinflated is far better than underinflated your answer/suggestion is just lazy.

I’ve weighed my trucks dozens of times, and never once did I go to a cat scale or pay for weight. It’s easy to find open weigh stations along your route.

My 31’ 5th is a real load and requires nowhere near max tire pressure.

Don’t suggest lazy, suggest accurate.

Fair enough, I can accept lazy in this case. You will not be able to blame the tires if something goes wrong and they are at max psi.

I'd also argue a 31' 5'er is not much of a load...8k lbs maybe? And I'd agree, for that load I'd run ~65 psi in a SRW set up on w/Range E tires.

Hmm, so max pressure isn’t a set and forget… is it. After all you just recommend a pressure lower than max for towing.

~8K on the trailer axles, not including pin weight. Puts me ~6K RAW with no additional payload in the truck. That certainly qualifies as “real load”…. I have a much shorter bumper pull that puts me closer to the RAWR… so you cannot judge “real load” by length.

Generally max pressure will not cause too many issues, but traction (braking and acceleration) is decreased, ride suffers, and the tire is more susceptible to road hazards (i.e. easier to puncture).

You know if the road sucks and/or its windy you might just have to slow down a little pulling your giant 5th wheel or travel trailer.

You have to take the load tables with a little grain of salt.

According to the tables for my BFG KO2 in 35x12.50R17, with the weight of my truck, and my larger tires, I should be running around 30 PSI front for 2155 lbs per tire. My front axle weight is 4280
Rear should be about 20 PSI. 25 PSI is 1875 lbs per tire. But my rear axle weight is only 3080.

But I think that's too low. I'm currently running 35/30 cold. I was running 45/37 hot for a while, but I got more wear in the middle in the front. My current hot pressure is about 40/35.

Is reading comp not a strong point of yours? All of my posts say max or near max psi. 65 psi is what id call near max. Thanks, Mr thread police.

Its also nice to see you agreeing with me that you are towing a load 99% of 1/2 ton trucks can safely tow. Not a real load whatsoever, so what are we even talking about?

While we're at it, you might as well dump your E tires for D's and get that REALLY nice ride!




HERE'S the real LOL -- you are a frequent flyer at the CAT scales with a 8k lb load? lmaooooooo. Do you break out your tire stick and pre-trip inspection book as well?

Come on guy, get ahold of yourself

Thanks for the comic relief, you clearly can’t read or think for yourself. Continue with being lazy and uneducated, but I’d keep that to yourself as it doesn’t help anyone.

In anything other than lazy math 81% isn’t near max. C‘mon man, think before you type. Help yourself out, at least attempt to appear credible.

Please show me the 99% of 1/2 tons capable of safely towing that, within their specs. I’ll wait… unless your 99% was also lazy.

Keep to myself?

I had to jump in when the guy towing a 1/2 ton load is trying to hand out load educations.




AH64ID pulling into the local CAT scales to make sure his tire pressure is correct!!!





Way to be safe, bud!

Youre welcome

Too bad you guys had to sidetrack my thread with your childish insults and idiotic posts that had nothing to do with my original question. It’s morons like you that are driving people away from forums to using Facebook groups instead. No wonder the owners of this forum don’t want to invest in making this site work any better.

Thanks. I hope that it works. I rebuilt the trailer suspension last year with wet bolts and cushioned equalizers and new tires.

You are just an internet blowhard who posts on anything you can just to hear your self and most of the time you are posting on threads that you have no clue about. Crawl back under your rock.

Sounds like he got you pegged

At the end of the day most people (not directed at you OP) just don’t care or even think about the important questions and answers when towing. Axle ratings, tire inflation, tongue/pin weight/trailer weight distribution, drop/rise hitch length, trailer brake setup, etc etc on and on and on.

It’s evidenced by all the crap I know everyone has seen here on our various public highways at times. They just want to know if their hitch ball is compatible with X trailer and if so they’re off to the races. It’s crazy what some people seem to get away with. They just don’t think.

When my wife and I went last summer to buy our measly little 5k gross single axle TT the salesman was surprised at how many questions I came at him with. Luckily he was quite experienced with trailers and towing and could answer all my questions accurately and in depth (which was one of the reasons we ended up buying from him).

It’s also nice to have a community to come learn from. Just gotta sort through some noise once in a while lol. Take what you need, leave the rest. And there’s no replacement for just doing it and gaining experience.
