I have not had any problems with my 670's, and I'm not sure they need replacing yet, I'll have the dealer look at them. DOT 2507 I cannot find even a hair of a crack on any of the side walls, but the dates got me concerned.
Why don't many of you like these tires???
The reason a lot of people don't like GY G670RV tires is because they wear funny on the steer tires, most of the wear pattern seems to be what is called river wear. Its worth to note that most of these wear issues are on 22.5" wheels/tires, not on the 19.5s. On my last unit, I had GY tires 8R19.5s. The fronts were G647s, which were excellent and wore perfectly. The rears were the infamous G159s, which wore well, but were old and not rated for highway speed on top of that, so I had two of them blow out. This was mostly my fault, because of ingnorance and stupidity on my part.
I had old tires that were maxed out weight wise, and I was going way to fast to boot.
A sure recipe for failure and/or disaster!
My current unit has GY G670RV 265/75R22.5 tires on it. The DS front is showing some abnormal wear on the outer edge, but besides that, the tires have done extreamly well, with no weather cracking or other issues, considering that they are almost 9.5yrs old. I think part of the reason they have held up well is because the RV weighs about 25% less then the tires' capacity, plus I drive much slower now.
That said, even though I don't drive real long distances, I do feel that at almost 10yrs old, they need to go.
Again, from my experience, the GYs age extreamly well and handle well too, especially in windy situations.
For me, the wearing issue is a big nuisence, but tire handling/stability, long life (age wise), and no blow-outs trump wear issues any day. I am open to other good brands like the Yokohamas, Toyos, Continentals, etc., but if the price is simillar I will probably stay with GY, because they have worked well for me. If it's not broke don't fix it...
By date codes, your tires are around 6.5yrs old, which for the G670's that is still a good amount of life, unless you are maxed out on weight and/or start seeing issues with the tires showing age. If you have neither, you should get a solid two more years out of them. Also, if you decide to replace them anyway, you should be able to sell your old tires as good used for about $600+. A lot of locals with dump trucks and old dilivery vans buy them for short distance use. For their application, they care more about tread depth then age. When I change mine out that is what I plan to do. Heck, if I can recoupe some of the cost, why not...
