Cool man, no offense intended... Though your wording of "pull is a Cooper thing" sounded specific.
Glad your BFGs are working for you

No, I was not calling out cooper. I really like their products. Just the Maxx has the pull and the BFGs don't. I have not had the pull in any other cooper tire I have had, or my hankooks. I don't buy toyo off road tires. My jeep will not wear any tire wrong, everything is in alignment up front. There is nothing to throw off that unlike a independent front suspension. All you can adjust is toe and that is set bang on.

I've had some pull with other Cooper-made tires, my ******** Cepek F-C II had some, but not as bad as the MAXX and only on the IFS truck not the straight-axle rig.
Agreed, I really like many Cooper-made tires.
Yup, I've owned several and still own a live-axle truck, where factory adjustments are few beyond setting the toe.

Me? Yup

I was more curious on the jeep... But assume your pull didn't change by switching the tires.
No it stays to the right, its a product of the tread design. As I said, my Cooper A/Ts and M+S never did it, nor does my BFG ATs. My Cooper designed Trail Cutter A/Ts do not pull either. The Maxx were the first set of tires that ever did that. I thought it was the jeep, As I replaced the stock tires with about 2000kms on them after getting 3 flats on the first trip off road.

My Maxx's don't pull though.
I have the 255 width.
What width did all you pullers have?

I am running the 295 70 17 maxx's on my '68 and am very pleased with the road manners truck drives better than it has with any other tire the one thing different about the maxx's compared to other tires I've ran on this over the years is the air pressure needed for proper tread contact is quite a bit lower I'm running 49psi front and 47psi rear and the truck weighs 8,000lbs when the tire shop put them on they inflated then to 53 front and 50 rear and at that psi the truck was all over the road like it had a mind of it's own and only making contact on ~60% in the center of the tread.

I'm running 34psi on my skinnies ---- I ran 30 on the 285 STTs though.
I love their manners.

I would think it somewhat unlikely that 4psi made that much difference. ?? More likely that they were squirrely when new due to the mold release compound, and you may have just burned it off as you settled the pressure some. Your truck isn't quite as nose heavy as mine, but the pressures you're running sound a bit low, at least on the front. I guess if you're not wearing the outer lugs, then the pressure is fine though!
I suppose it depends on the wheel too. A narrow wheel will require less pressure for even wear. If you're running a 7.5 or even 8" wheel with a 295, that's on the narrow side, and would explain the lower pressure, and the squirrely handling when it was only running on the center lugs...
Glad to hear they're working for you! Nice to see the old '68 getting some miles on it!
