I've been eyeballing my load range G Goodyear tires on my fifth wheel for a couple of months thinking they would need replacing soon. Coming back from Death Valley to Texas I am stopped in Deming, NM and decided to take the rig by the Goodyear dealer. He feels that they need to be replaced before getting back on the road. They are wearing on the edges, outside especially. The middle treads look fine. I have always kept a little over 100 cold psi in the tires and my rig weighs about 15K. One of the tires is 4 years old and the others are 3. They probably have less than 20K miles on them. The tires were made in the USA. The Goodyear guy sent me to a place to check the axle for alingment and the axle guy said that he had had several load range G Goodyear tires in lately and that mine were displaying what he considered normal wear for these tires. The axle is ok. He also informed me that I probably should plan on replacing these tires every 3 or so years. I have purchased and am awaiting new tires to come to the dealer for install Tuesday.
I purchased a tire monitoring system several months back thinking I could extend the life of the tires in doing so. It doesn't appear this is the case.

The Goodyear G rated tires have always wore more on the outside then the inside. I agree that it's a good idea to change out the Goodyear G rated tires at no older then 4 years, no matter how many or less of miles. I changed out four this spring. The spare now is only 3 years old. The tire before it was changed out due to a nail in the sidewall and was told it couldn't be patched. I should have got a second opinion. Be sure you check the built date on them since I had the place I went to tried to get past a year old tire. Built date is after the DOT numbers. They are 4 numbers. The first two is the week they have been built. The last two numbers is the year. So 4111 is the tire was built on the 41st week of 2011. We had our trailer weighed in 2007 by weightit. Our trailer weighed 15,015 pounds. Was told to run the tires at 110 psi.

IT is difficult to believe that tire sales people are now telling people to change tires every 4 years. It is like changing shoes every few weeks next!
I still think that you should be able to get 6 years out of the tires. I wonder what is being put into the tires this time that is causing the tire life to drop so dramatically? Back in the 70's it was common for a tire to last 10 years, when in a low mileage situation.
I would have kept running the tires until the minimum wear bars started to show up. Surprising how many more miles you can get out of tires that way. My boss said "Keep running those tires" to me, when I showed him my tires on the GMC 2500 truck I was driving. I think he wanted to replace the truck, and sell this one, so I kept driving another 4,500 miles before the wear bars started to show through, and the tires had to be replaced. I was surprised on the extra miles I got out of the tires, something I would not have done with my motorhome, but it was his vehicle, and he wanted to get the extra 10% out of those tires.
Uneven wear is not a reason to change tires, just "Adjust" the tires you have. Thick tread in the center while thinner at the edges indicates the tire has more load than the air pressure is set for. Try running 10 PSI higher, and the tire tread should start to wear out in the center. As long as you have 1/8" or more tread towards the outer edge, then the tires are still OK. Yet below 1/8" tread on the outer edge, I would have recommended replacing them too.

And if you are already at the max pressure for the tire then what?

I ran mine at MAX 110# and had even thread wear/contact across the tires.
Hardest things on RV tires........sun exposure, under inflation and low miles.
X2 on running the G614's at 110 psi....my 5er specs recommend running the tires at max sidewall psi of 110 and loaded at a little over 15,300#, I run them at 110 psi..
The way they are wearing, does sound like they're under inflated....I'd say they should last 5 yrs, but guess it would depend on how they wear and how many miles are on them...

I forgot to mention that the sidewall leak due to a nail is the death of a tire. So is driving on a tire only inflated to about 50% of it's maximum air pressure with full weight on it for more than about 10 miles.
In both cases, the sidewall flexes so much that the patch will leak or come off in a short time, perhaps even at the maximum tire inflation rating, then more air will quickly leak out and boom! WHen they take off a tire to inspect it before putting on a patch, they look for signs of excessive flex, and recommend changing the tire if the inside of the tire shows signs of cord damage, and that happens in a few miles at 50% of max air pressure. Yes Ford studied it.
