Advice on tire issue with fifth wheel

For sake of discussion and for the OP, here are my thoughts on the issue:

I've got about 30,000 miles on my G-614's aired to 110 with my 15,000 lb fifth wheel and they look brand new, so I'm a happy camper. No excess wear on sides or center and never a problem. I know that there have been reports of excess edge wear at lowered pressures but I have no first hand experience of that.

The downside to running less air is less carrying capacity...the upside to less air is a softer ride.

The downside to airing at max is a stiffer ride and the upside is max carrying capacity for the tire.

For me, the maximum carrying capacity is why I bought the G614 tire. It is pretty darn important with the dynamic forces at play in top heavy trailers being pulled down the road.

As they used to say...you be the judge...but I don't care a bit about a smoother ride in my fifth wheel...nobody in there. I definitely value the max carrying capacity at the weight of my fifth wheel. In fact, one of the advantages to me of a stiffer tire is better towing performance...there is significantly less sway based on my experience.

One of the disadvantages to static weighting is that it does not factor in the forces at play when you are swaying, cornering etc. while driving down the road.

The dynamic forces of the weighting/un-weighting are, in my opinion, one of the major factors in the tire issues experienced with minimum spec tires on trailers.

Many will argue that tire manufacturers build reserve capacity into their tires, but I say read the threads on here about tires and decide if you want to rely on that.

Hey, I'm no tire expert. Either way, I suspect the OP will be much better off without the towmax.

Another recommendation for max psi.....

Thanks!

The set I ran that replaced my GY E's had around 20K running at 85PSI and the tread was perfectly even. GY Tech told me if I ran the pressure at 110 the ride would be harsh and the braking would suffer and the centers would wear.

That is my experience.
