    I also sprung for a set of Centramatics with the Michelin steers. The difference is amazing. No vibration, wobble or pulling to the right anymore. The only problem is the manager at the Joplin Petro wouldn’t give me any credit for my casings. He said some of the new Chinese tires are getting better and he could have sold me Chinese steers for about $750 a pair instead of the $1134 I paid with the company discount.

    Careful making blanket statements about tire pressures. I run 90 in steers and trailer and 80 in drives..

    Perfect flat tread all the way across. I used to run high pressure like you but found it only caused a rough ride.
    No increase in fuel economy
    No increase in tire life.

    These have about 160k miles on them at 80lbs F0CB1CB6-5158-4147-A483-1577E8F4B3F0.jpeg

    Do you always run light loads?

    Its amazing what people believe. Yoko 703zl about 100k on mostly 2 lane. 90psi. They like to hold stones however.

    My bridgestones also love to pick up gravel and if you leave it in there it will wear a hole eventually.

    When Im waiting I just walk around and pick stones. My lot is stone, and Im in and out of a lot of elevators. Rock drilling its called and can ruin a tire or casing.

    Just general flatbed freight. %20 deadhead. I’m at or close to gross weight maybe %40 and the rest real light.

    When I replace my drives I’m definitely gonna look for a tread pattern that does not like to eat gravel.

    I'm running all Goodyear top line tires. There are better brands out there for sure. What I mainly get from GY is great value and consistently good service everywhere. They have a great network of company owned service centers, and even the franchise dealers are usually also very good. The dealers that carry the better brands usually fail to have the consistently good service network. At least where I run anyway.

    I also avoid specialty tires that aren't widely in stock. I ran into that when GY came out with their G505 fuel efficient drives. Catch some debris and need one or two out in the middle of nowhere? Now you're buying two tires. One to get you home, then when you get there you buy the correct one to match the rest. I frequently see posts by people buying the top line Michelin and Bridgestones, complaining they're out on the road somewhere and the tire they want (that everyone else wants) is out of stock and either they end up waiting for a out of state delivery or settle for something else to get going. I have never had that problem since I started using Goodyear exclusively. Sometimes the 16 ply steers aren't readily available, but the Endurance LHD/LHS drivers and trailers are in stock everywhere.

    Be careful about different lines within a company. They may appear to be the same, but the lesser brands are definitely lesser in quality/service life. I can speak to this first hand wrt to Goodyear vs Dunlop vs Kelly. In the Goodyear universe that is listed from most to least expensive. All 3 use the same molds, so you can barely tell them apart just looking at them. However, the Goodyear brand tires are better constructed internally and have a superior rubber compound in the tread than the lesser lines. The wear is proportional to price, so it's not like the value line is a rip off besides time, since the only difference is they have to be changed out a little sooner. Can't speak to the value lines of the other big brands since I never used enough to know better.

    That's a little low IMO, but I know nothing about what sort of duty cycle you're putting on them. If your doing a lot of local/regional P&D, that might be ok. I run top line Goodyears (G399 is now Endurance LHS) and they usually last to 160k before I take them off, doing mostly line hauls 600-1000 mi, usually on the heavy side. With some front end work that's due, I could probably squeeze another 20-30k out of a set. That said, I don't wait till they're at the limit to change them out. Even more so when they're wearing down right before the start of winter. Someone cheaper than me might get more miles because they run them down to the minimum no matter what.

    So the answer to your question is maybe.

    I'm with you and @jamespmack on reading the load charts. I go a little higher than the listed pressures and end up with even wear through the life of the tires.

    That said, I run my 16-ply steers at max pressure because mine runs heavy. Another thing I haven't noticed mentioned here is how 16-ply tires tend to suffer potholes and curbs better than the usual 14 plys. They cost me about $25 a piece extra, and well worth it from an endurance perspective.

    One of my trucks came with new Chinese 14-ply steers on it from the dealer. They lasted about 40k miles before the casings were beat up. Don't even waste the money on those even if they cost half as much.

    On the drives I got 80 psi cat's eyes and usually run them at 95-100. My trailers have inflation system on them set at 95-100. My logic is to set the minimum at whatever pressure lines up to the max axle weight divided by 3. That way when one tire on a dual axle goes, the remaining 3 have the capacity covered with a little margin for error.

    My experience with max or over inflation mirrors yours. Rides rough, wears out the middle first, and really minimal fuel economy benefit.
