Apples and oranges Burbman.
Hence my post why SRW diesel pickups tend to have less front tire issues than drws. Bigger, wider, much higher rated tires on the front of a srw vs the pizza cutters on a dually.

Close to 4 years and over 20,000 miles of rough and gravel roads carrying a heavy camper! What do you expect?

I have had worse. I drove 20 miles on a gravel road with new Michelin tires and had a sharp rock drive right through the center of the tread of one of those tires and totally destroyed it. The guy at the tire shop told me it happens all the time.

Well, we do expect and have had puncture issues on various roads. Our tire plug kit took care of those nicely. We also expect tread wear. What we didn't expect, even with lots of gravel and rocks, is the tread separation.

Swung by Discount Tire and they confirmed tread separation on 4 of our 6 tires, 2 fronts, 1 dually each side. Probably some kind of defect. Fronts still had 7/32, rears 8/32. Cooper Tire will give us a prorated amount toward new ones.

Talking to the Discount Tire guy, we are now considering the updated version of Cooper Discoverer AT/3 LT and the new Toyo AT3. He does not recommend the KO2 as the heavy truck/torque will shred them faster.

Question now is according to sales guy:
4 new Cooper tires for rear and put remaining 2 supposedly ok tires on front until they are done (slight change in tread design), not liking this option
or 2 new in front, 2 new one side dually, 2 old other side, seems weird
or 6 new Toyos and keep old Coopers as spares, probably this one...

If I remember right, I think you can tell if all of the tires are from the same lot or not. At least, you can tell if they have the same date codes. If they are in the same lot or are produced about the same time, I wouldn’t keep any of them on my truck. I think Cooper should refund those at the same time. The chances of those other two not failing is not very good in my opinion.

As far as brand goes, I have no experience with Coopers.

I put Coopers on my F350 and had wear issues as well. Replaced them after 2 years and around 35K miles and went back to GY's. No defects in them just unusually rapid wear on all four corners

They were not worth the savings.

I just switched to Cooper HT3s for my F-250 because after 3 sets the Goodyear Duratrac did not last like I thought they should.

I have always had good luck with Cooper tires so it was a natural switch for me.

OP, those tires have seen LOTS of gravel, haven't they? I grew up living on gravel, I have seen that before.

I replaced my factory Michelin AT2's when they wore out with less than 30,000 miles with Cooper AT3 XLT's. For those that may not know current Cooper AT3's come in three different designs 4S designed for SUV's, LT, & XLT for heavy loads.

I did the complete opposite. The Duratracs have twice the mileage on them as the HT3's and way more tread left. Superior snow traction, abrasion resistance and they look WAY better on the truck.

What works for you, works for you.

Define "really light"?

Sadly, those tires have seen a rough life.

I have the same tires on my dually and they have performed flawlessly. I've had them since 2014. I will probably replace them due to end of shelf life instead of "end of tread life." Tread still looks good on them, but I never go off pavement.

Just an obvious question for you ...

How can you possibly say they’ve had a rough life when you don’t even know how much he’s carrying? [emoticon]

I think we are talking about defects in the tires in his case. As noted, I’ve never used Coopers, but based on this thread, it seems reasonable to think that it’s possible that thedavidzoo has experienced multiple defects. That is, unless you think it is acceptable for the tread to separate from the rest of the tire.

I think the phrase ... YMMV definitely applies when we are talking about tires. [emoticon]
