Any CP3 issues on 6.7?

Uh, yeah, they do have factories that employ many Americans right here in mid TN. I know, because they are one of my customers.

I don't believe that Tuesdak was doubting the fact that Bridgestone/Firestone manufactures tires here in the US, but rather was doubting the fact that the company is American owned. Toyota, for example, has manufacturing plants here in US but they are still foreign owned. Cooper and Goodyear are both American owned and manufactured, as far as I know.
 
American owned is a bit of an oxymoron.
Cooper merged with Apolo Tire several years ago. So they are at least partly (or possibly majority) owned by an Indian company. And GY sold to Continental Tire which I think is German or Belgium.

Both manufacturers headquarters are close to me in Ohio, Cooper in Findlay and GY in Akron and was big news when both happened.
 
My recent realization that brand loyalty and perception being in the toilet is ringing so loud right now! You simply cannot blindly return to a manufacturer of anything after many years and expect the same.
This is a great discussion, and my own opinion is that other than the old Eagles, I never liked Good Year. They always had quality problems. My ‘14 Durango had Forteras and they were okay but I think a cord was going bad towards the end. BFG on there now, and that’s what I’ve been buying lately with success.
I always liked Cooper. What about other brands like Uniroyal, General and such?
 
Of the 6 GYs that came on my 74 Chev C60, 3 had "knots" on them. Sets of Vectors on my wife's Buick and my Silverado had to be prorated replaced and and the new ones went bad very quickly, too. Replaced them and cut the sidewalls so they couldn't get on someone else's vehicle! I haven't been interested in anything GY has had to say since. I run itsy bitsy stock Michelins (originals went 103k, 2nd set about 78k when a belt busted,so I replaced all). I don't haul/pull much, but my measly 555 torque 5.9 has its hands full with 23k. I can run overdrive at 58 mph, which I would never be able to do with a taller tire

I admit that I wasn't always a big fan of Goodyear either. Like you, I liked the old Eagle tires they made. The stock Wranglers that came on my old 98.5 Ram 2500 (my first Ram diesel truck) were totally worthless on anything by dry pavement. They broke traction a lot on wet roads and were totally worthless in any kind of snow. I'd have gotten just as good of traction with a set of racing slicks on. I then went to BFG's and ran them for a long time. My only complaint with them was that they would slowly lose traction as they wore (yeah, I know most tires do that, but this was noticeable to me at least). Then the guys at the tire shop I go to told me about the redesigned Wranglers. I was really skeptical to try a set because of my past experience with them, but they said they were running them on their trucks and liked them. So I tried the Silent Armors. I wasn't holding my breath on them, but was pleasantly surprised when they actually performed quite well and they were a bit cheaper than the BFG's. Since then, I've ran a set of just about all of the Wrangler series tires (except for the Mud and Snow tires). I had a set of Duratracs on my old 04 Ram 2500, but sold it no too long after that, so I didn't really get to try them out that much. The Trailrunners that I have now have also done fairly well. I've noticed that the Wranglers pretty much keep good traction until they get really worn. As I said, I have 53K on the ones I have on now and they are just starting to lose a step traction-wise. I put a set of Duratracs on my wife's 2500 last fall and she likes them, although now she's ready to yank them off and burn them. LOL!

I never had any particular brand loyalty to Goodyear. I kept running the Wranglers because they always performed well for me. To be honest, I was actually somewhat looking for an alternative to the Duratracs when this whole thing exploded in the news last week. That took the somewhat out of it and made it definitely. I really appreciate everyone's comments here and taking the time to post! Some of you have given me a few things to think about as well.

My wife is about ready to do the same to the Duratracs she has on her 2500 that you did to the Vectors you had. LOL!
 
I also ran a set of the Silent Armors on my 98 and have to admit they performed very well. If you were happy with the tread pattern and performance of that tire the AT3 XLT is very comparable, with the exception I haven't got enough miles on them to speak to their longevity.
 
Have had some good luck with the GY Silent Armors. I would run them again. Not exceptional for tread life, but, made up for it in tough over the years as we ran them in the oil field for a fleet we were in charge of long ago.

The BFG's are known lately to experience tread cracking and very short life. It was the last set of tires I put on my 1993 hot rod and they wore out fast. After taking a 1" dia tree branch (road debris) in the sidewall of the last tire set I liked the heavier sidewall on the BFG. It's a good question if there were redesigned lately to cure these problems.

Why yes, the parking brake did slip... Can you identify what it ran over?

I had over 40K on a set of ridge grapplers. Towing a fifth wheel and some off road stuff. I liked em. Great all around tire. I had the Toyo MT tires. Popular when my 06 was newer. I wasn't diligent with rotation but noisy tire and very short wear.

Mr. Lizard, I presume.
 
Ive been running the Cooper Discoverer AT3 tires and seem to be wearing really well. There onl y a 265/70r17 but with my lowered 2wd they fill the well plenty and ride great. some roads leave more to be desired.
My friend's been running Coop's for ages. He has had some issues with balancing but going to a different Discount Tire has done the job. Super quiet and long lasting.

The NRG's are reported to be really quiet for their semi-aggressive tread pattern. They're about $25+ per tire over the Toyo AT111's and have no wear warranty. My friend's a Toyo dealer and the Toyos are way back ordered through his distributor.

I bought a set of BFG AT/KO2's as soon as they came out a few years ago. All 4 tires had sidewalls that were splitting at every side lug in the tire all the way down to the bead. Discount Tire didn't flinch and warrantied all of them with under 10k miles. After being a loyal fan for years I had my fingers crossed the KO2 was going to fix the issues they've had but they haven't.

I've been stung enough by those things to know exactly what it is, good kill.
 
Another vote for Nitto tires. I am using Nitto Dura Grappler LT285/70R/17 126R tires on my truck for the summer towing season. These are mounted on Mickey Thompson Side Bitter II rims. For winter I use Michelin LTX M/S2 LT265/70R17/E tires mounted on the factory rims. Never have been a fan of Goodyear tires. For all of my vehicles I have never purchased Goodyear tires until this year for my trailer. I had to go with Goodyear G614 RST 235/85/16 tires that replaced my Westlake ST tires, since they aged out and I could not find the Westlake tires at Discount Tries that would fit my trailer.
