Bret,
Knowing what I know about tire failure rates (and the fact that you got what seems to be a minimal adjustment), I think you may have something in your operation that could be improved and would result in less failures (and the ability to use a less expensive product!) I agree that not only would the personal service had been better from someone locally (rather than over the internet), but they might have been able to point out what it is the might be prompting these failures.
Perhaps it is something as simple as your tire repair guy using plug type repairs, or something like insuffient load carrying capacity. Nevertheless, I think you ought to take a quick look at your situation - might save you from a bigger problem.
Thoughts?
Hi Capri,
Just noticed your reply, thank you.
I bought the 10 Kumho Venture H/T's for our two largest service vehicles. One is a dually F350 with a service body and the other is a SRW F350 with a service body. It's the dually that's had all the problem tires.
All the tires I bought were LT235/85-16 LR-E. They're all run at max pressure (80 psi IIRC) or very near it. Tire rotations are rare to non-existent. None of the tires were flat repaired.
The dually weights right at 13,000 lbs with driver. It occassionally tows a 1,000 trailer. The SRW truck weighs about 10,000 lbs with driver and tows the same trailer more often.
Of the 10 Venture H/T's I bought for both trucks, only two have been "good", meaning I've got normal tread life out of them. The SRW truck still has the two Kumho's on the rear. I'll pull the service file this AM but I'm guessing I've got 30,000 miles out of them which is pretty normal for commerical tires on our trucks.
The dually situation baffles me. It came with General Ameritrac tires as OE and we got 45K out of them. Replaced them all with the Kumho's. After having the tread separation issues I replaced them all with Cooper Discoverer H/T which have about 15K on them now. Driving conditions and maintenance procedures have not changed. Load changes a bit depending on how much steel we're carrying (it's a welding truck) but the overall weight rarely goes beyond 13,000 lbs.
Thanks for any insight you can provide.
