Goodyear G114 Tires

Set upper high pressure alarm for 150 psi

No need for concern with the increased pressure from COLD stationary to HOT rolling down the HWY

What is concerning is when ONE tire goes higher/hotter then the others.

Tires on same side of 5vr should be close in pressure/tamps
Tires on sunny side can run higher/hotter then those in shady side

In strong side winds the down wind side tires will also run hotter do the the extra load placed on them. Chris

I run my G114 at 125psi cold. Interesting story I had over 20,000 miles on the trailer at that time. All five of my original tires have been replaced due to failure. The first one was missing a chunk out of the thread about the size of an ice cream scoop. One was to far gone to tell by the time I found it. Two lost thread and the core remained and still held air. Then I found two with waves in the thread. Anyway the last two was found when I was at Moryde in Elkhart Ind. Went to the Commercial Goodyear dealer and I was not a happy camper. Anyway he told me he had a number of G114 failures and the common denominator was a July 2014 manufacture date. Corporate Goodyear is on board with the 125psi. I run TST monitors, the one that blew the monitor was not on the tire. In for warranty work. The other tires even though half the thread was gone still recorded PSI and temps with no problem. Moral of the story for me is there are good and bad G114s.

I have a friend who lost 2 G114's in 2 days last summer in 100+ degree Arizona heat. The tires didn't blow, the tread separated from the casing. The tech that did their second road call told him the cause was heat-induced pressure increase and that the should be inflated to no more than 110 psi cold.

We have them on our rig and that's the way I'm going to run them.

I think a call to GY tech support would be in order. My DRV is 23K and has two axles that weigh in at 17,500#. I have traveled in hot weather even at 75mph with zero issue running 125psi.

Per GY Tech they say add 5psi to the heaviest tire on that axle. I have always used the tire inflation charts. I DO run full 125psi on my GY "H" tires since my combined axle weight is 17,500#.

Another believer in the G114's here...

I figure I will know when I hit something just as fast as a TPMS could tell me... I have not heard of any issues with the GY G114's

I've had 3 blowouts with them.

And if you do happen to get a nail or something, and get a slow leak ? Tire gets low on pressure ,heats up, and blows.


I can only imagine what an H rated tire with 125 psi does to a trailer when it blows. I have seen the results of the Goodyear G614's when they blow ,its not pretty. That monitoring system would seem pretty cheap at that point. Thats JMHO.

Thank so much, really appreciate the responses and the help!
