I don't understand the fascination of running things like tires and trucks at 75-80% rated load. You think anyone commerical does that? Hint: they don't. Waste of money and capability.
Do it if it makes you feel better - but don't pretend it makes sense. Because it doesn't. Financially or otherwise.

Tires are designed to be run at 100% of their load rating at their rated speed. Not occasionally. Not rarely. Every damn mile.

Now that said - I run Chinese tires and have never had a problem with them - granted we've only done about 30k miles in the last two years....

Sounds like you are over due for a blow out! Keep both hands on the steering wheel and drive safe.

On the tow vehicle it makes a big difference.I tow with dually have 4,200 on the pin.load rated e tires set at 80psi.Now unhook and run 80 psi and you will wear center of tread off.Air down to 60 psi when unhooked,if driving substantial miles unhooked.

Is that in accordance with the recommendations in the vehicle owner's manual or just a (IYO) personal or from your personal experience recommendation?

It is from my experience,last set of tires I wore the center off.My tire dealer told me to air down when unhooked.Just put 4 new transforce tires on and will air down if driving extended miles unhooked. I have onboard air.

Check your drivers door sticker, your dually probably suggest 65 psi for unloaded tires.

Interestly, way off on mine(see below) but shows 65 loaded—and sorry to OP for continuing off topic- even as full timers, I tow heavy 40% of the time...I’ve been seeing more wear in the middle of my Transforce E outer dually tires (than my inners—slightly newer) even at 60 psi for all four. So I aired down to 55 two or three mos ago (temp in 80s) and they since permeated down to 50 at 58 degrees when I checked right before this MI trip. I don’t use valve stem extenders as an easy back n forth solution. But with TPMS sensors attached, they have been known to leak. I’ve had great service from the rear tires so far @ 57k miles.

Want to buy Sailun 235/80 16 load range g tires. Need to upgrade the wheels to handle the 110 psi tires.

I can't find a Sailun load range chart anywhere. Dealer is saying run 85 psi, I'm thinking 105. Both are guesses. I know I'll be a little rough inside with the increased pressure, but want plenty of capacity/safety.

Anyone seen a Sailun capacity chart, what would you recommend?
I use the same Sailun's. 105 is what my dealer recommended. I think you can find a chart or at least the info you need at www.simpletire.com, the online dealer for the Sailun brand.

Were your "blowouts"
Belt separations or were they sidewall flex failures.

Are you mixing new & old tires in a pair of duals? If so that is asking for problems unless you have confirmed the OC is within 3/4" or less.


You can learn more by reviewing the posts on "Duals" on my blog.

Sailun does not publish tables only the tire max load. They say to follow Tire & Rim tables. They do have some high load tires for trailers HERE. You will have to do some checking to find a US distributor. Note I have found some inconsistencies in their data so be sure to confirm with the dealer before spending the $.

I put identical new tires on the inside dually 1000 miles after I bought it used. They were definitely mismatched when bought, see photo below. The dealer or previous owner put 4 new Transforce (fronts and rear outers) I’d estimate within 500 miles as I still could see the little nubs on the tread. At some point the rear tires(inner or outer) had a failure as there was damage to both fender well liners and metal frame support rods. All fixed now.

I took a picture of the one trailer tire for Discount Tire replacement claim.
