Ronbo Posted April 7, 2017 Report Share Posted April 7, 2017 I put this in HDT because that is what I tow with and I always monitor here. I had two tires come unzipped today. They did not loose air. This is after having another one do it less than 2000 miles ago. All tires were replaced last year. They are Goodyear g114. I inflate to 125 psi. They are not overloaded as I have had weights checked. I get them at Discount Tire so I only have to pay $90 for road hazard warranty. They way it is going I will never have to pay full price but Discount a Tire needs to start installing full hookups for me. I have a morryde independent suspension installed. I run 60 mph. They are not wearing funny. this had happened 6 or 7 times and my TPMS does not alarm because they don't loose air. They are not old tires, I check the dates when they are installed. Any ideas?

NeverEasy Posted April 7, 2017 Report Share Posted April 7, 2017 125 psi sounds like a lot. Could it be an over inflation problem? Those Goodyears are usually good tires.

rickeieio Posted April 7, 2017 Report Share Posted April 7, 2017 125 psi is the max rated pressure for that tire. And yes, we had good luck with them. Too bad the wheels wouldn't work when we updated our trailer.

Brad & Jacolyn Posted April 7, 2017 Report Share Posted April 7, 2017 I agree. That sounds like a lot of pressure. I only run 95 pounds in my G114's.

Jim & Wilma Posted April 7, 2017 Report Share Posted April 7, 2017 Ron, You might consider checking alignment on your IS. You'd expect it to show up on tire wear pattern, but . . .

lockmup68 Posted April 7, 2017 Report Share Posted April 7, 2017 16 inch rims? or 17.5? What are your individual wheel weights? Same position that keeps going? or which positions? 2003 International Eagle 9200i, Cummins ISX, Freedomline 2007 Teton Scottsdale XT4 Link to comment Share on other sites More sharing options...
GlennWest Posted April 7, 2017 Report Share Posted April 7, 2017 The 16" Goodyear's done this. They were faulty tires. Only other way likely is heat. But with the air pressure you running that shouldn't happen. I would call Goodyear. 2003 Teton Grand Freedom towed with 2006 Freightliner Century 120 across the beautiful USA welding pipe.https://photos.app.goo.gl/O32ZjgzSzgK7LAyt1 Link to comment Share on other sites More sharing options...
Ronbo Posted April 7, 2017 Author Report Share Posted April 7, 2017 I had my weights done by Trey. I a, below max. Also had them done again at morryde. If the axles were out of alogianment I would have abnormal tire wear. 125 psi is correct for my weights. The rims are rated for this. It is not position dependent. Weights are 4300, 4200, 4450 and 4750. The only one close is the 4750 but I have removed some weight since having it weighed.

Tireman9 Posted April 7, 2017 Report Share Posted April 7, 2017 By "unzipping" and since they didn't loose air I assume we are talking about belt/tread separation and not sidewall blowouts. Tread/belt separations are usually caused by long term heat + age with heat coming from high load (for the inflation) and high speed. GY/Discount should be adjusting the tires especially since you have the weigh slip records. This type of failure can not be detected by TPMS but sometimes can be seen before the tire comes apart if irregular tread wear and out of round are observed. HERE is video of a tire that was in process of failing. Here is my blog post on what was discovered on my examination of the subject tire.

I don't understand that the TPMS can not detect the tire temperature. If you are saying that long term heat +age with heat coming from high load can help cause the problem. What tire temperature are you talking about ? I thought that most TPMS were set at 158*F. Can you please explain more about temperature.

Short answer is that with increased temperature rubber ages or looses its strength at an ever increasing rate. This post on why tires fail also covers the rapid aging of hot tires. TPMS temperature is just the current temperature and is not set up to predict long term tire life. But cooler is always better than hotter.
