I have a 2020 Trail Boss.  Has anyone switched out the Good Year duratrac tires which are load range C for the BF Goodrich K02 load range E?  I have a lot of trailer sway with the good year tires, they have soft side walls.  I want to switch but am unsure how to change the factory tire pressure settings.  The K02 tires run 80psi compared to the 41psi on the good years.  I don't want to get alerts for high pressure from the chevrolet app.

What type of trailer? Travel trailer?

 

If so look into weight distribution hitch. And if you end up replacing the tires let us know if that improved it by much

I tow 3 different trailers.  17ft Ice Castle fish house, weighs about 4500lbs, 25ft travel trailer about 6000 lbs, and an aluminum 12 ft trailer for side by side.  The travel trailer I use a weight distribution hitch with sway bars, it still does not help.  The 17ft trailer is the worst, almost scary at times.  The 12ft trailer tows fine.  I towed all 3 of these trailers with my Tundra using the BF Goodrich K02 load range E tires.  No sway at all.

That is why I was surprised when I bought the trail boss that it tows so badly.  I figured it must be the load range C tires.

i have 275/70r17 k02s on my 2104 chev that are e rated. these tires have a load rating of 3195 lbs. i run the tires at 50 psi. i tow an enclosed trailer weighing approx 7000 lbs frequently and have no problems. these are great tires for every type of road condition. the down side is they are heavy which means your fuel mileage will take a good hit, but if your towing a lot it doesnt matter. the ride is good for an e rated tire. the other down side is they start off fairly quiet but that doesnt last long . they do become very loud to the point i thought my front wheel bearing were shot. i have put over 40k miles on the tires and traction is still just as good as new. running higher pressures than the door sticker doesnt set off any alarms on my truck

Any chance you've changed the weight distribution on/in the trailer?

 

May not be the issue, but changing weight distribution can change the way a trailer pulls --- and induce sway.

I tow a 6K trailer with an 800 pound tongue weight on stock tires.  No sway.  I do feel some slight sidewall flex, but it is not sway.

This. make sure there is enough tongue weight. If the trailer's center of gravity is too far back, it will sway like crazy.

Also this. The pressure indicator light is only when they sense too low of pressure. higher won't light up your dash.

 

If your trailer's tongue weight is within what the truck can handle, your OEM tires should be adequate for that load. I wouldn't put load E tires on unless you pull the trailer daily and don't care about the ride quality when unloaded. That's not to say the OEM tires are great and you wouldn't be happier changing them out.

Stock Bridgestone Dueler A/T tires on my 2020 High Country 5.3 10 speed. I pull this 7000 LB travel trailer with no sway and the stock tires are fine. I do use a Recurve R3 weight distribution hitch with sway control.

      Some Assembly is Required

      Gas Prices

      By Grumpy Bear · Posted

      We drove about 15 minute east today to visit a friend and saw a steep increase in price in the same county. About 50 cents a gallon steepper.

      Wow I'm in a pickle. (Broke down truck) and a story.

      By Grumpy Bear · Posted

      Sure about that? A degree wheel and a dial indicator would lower your degree of assurance in that statement. 😉    It why we have offset keys and dialable timing sprockets. Just say'n.... I've built a few and have never seen one "On the money".

      Tire psi

      By Chuck FB · Posted

      I will admit I haven't experimented much with pressure drops beyond the numbers I put in and part of that is that the numbers I used are fairly low and then found out it would trigger regardless at that 35 psi. Having said that I had tried before had changed the placard pressures and being that I have a 1 ton set to 80 on the placard for the rear I believe it triggered close to 60, the front I don't recall now for sure but thought maybe it could get close to 45 from that factory 60 placard pressure. So I never did figure out if it was a number of psi from placard pressure to the alarm or a percentage of the total placard number as some figured it was like a 25% drop from placard pressure would trigger it. So as to try and answer your question, I believe I set the placard pressure on the front to 47 or so and while I run the front tires at 40, they have dipped below that some if its colder and I haven't put "winter air" in yet and never once have had the front alarm go off. I would say that the answer your looking for is no, that if you set your placard pressure to 45, you have a certain amount of room to drop below that pressure before the alarm will go off.    The pressures you decide to run in your truck, that ends up being what makes sense to you based on what your carrying in your truck or if towing, then have to bump them back up to something that will carry the load in the rear and the fronts typically left at the same pressure. It all comes down to that chart I put the link to and using an accurate roadside scale to be your guide, both unloaded and then loaded to know your minimum safe pressures.    I just wish GM would allow a person to change the readings for the tire pressures to the English system of pounds as I have to look at that goofy metric reading that will never ever jive in my head and will go over and change it just to figure out what they are if need be and then change it back.

      No Software Updates - Old Build

      By TrueBlue · Posted

      That part I understand, that the dealer can do it. But I'm not understanding why updates that were available to the truck since it left the factory, or the dealership originally, would not still be available to it without dealer intervention.   I'm thinking along the lines of recalls. They stay available until they are completed, regardless of whether they are in warranty or not, or in the hands of the original owner or not. Why not updates as well, especially since some of those can be safety related also?
