KO2 Wear

[arich]

Sinister.
Ours look quite similar to each other's. It might me our NY roads.
I'm going to rotate today and maybe go back to the shop this week and dial in a little more camber.
I need to get my wife's GL checked too. Her new fronts are feathering on the edges.

I'm not gentle on the truck either, but yes the roads here are probably one of the worst in the nation. Absolutely horrible.

The joints in your SPC arms still looking OK? There is a thread in the 100 forum about SPC ball joints failing (first evidenced in uneven tire wear) after only a few thousand miles. More than one case of this... I'd check them if you haven't already.

Roads in NY are very rough unlike CA and the south where everything concrete.

I'm not sure what "south" you are referring to, but the south I live in has very few concrete roads (interstates in some places) and lots of beat up, pot holed asphalt roads.

In regard to the air pressure, I suggest that you try chalking your tires

Google

Another thing to consider is finding BFGs actual recommended PSI for your vehicle. The PSI that BFG lists on the tire is for a certain weight. If you proportion that PSI/weight ratio to your correct weight the tires should perform the way BFG designed them to. I was getting bad wear on my KO2s on my previous 3/4 ton truck and after correctly proportioning the tire pressure they rode better and wore better.

NY city roads are bad, but Chicago winters obliterate ashpalt. There are some areas on upper Wacker Dr that were so bad until recently that you could see lower Wacker Dr below!

In fact Illinois was rated the worst in the country last year with "73% of roads in poor/mediocre condition" by the DOT.

Elderthread question. @Taco2Cruiser are these settings (quoted below) still considered 'known good' for a 200 w/ BP-51 and UCA setup?

I'm headed to a MUD-recommended local alignment shop tomorrw. My steering wheel is off (no VGRSS), poor return to straigt, low-speed vibrations (assumed to be from bad alignment, and signs of funky tire wear.

Anything else I should ask them to adjust?

camber should be 0

toe the tires in a 1/32"

Caster is generally better to push to the positive, but if I get camber at 0 with a perfect toe in and the steering wheel perfect, a little negative caster using worth listing those other good attributes.

Front Caster
2.9±0.75

Front Camber
0.13±0.75

Front Toe (degrees)
0.24°±0.16°

Front Toe (inches)
0.12±0.08"

Here is factory specs, but it’s basically the same as I described, just organized a bit better.

The 200 series platform is a great platform, but it’s not easy to modify it heavily. Simply swapping coil overs and control arms is not very invasive. So sticking with factory specs is what’s good for almost everyone.

great. thank you. I'll talk to the tech about these numbers, and also check if they have experience w/ adjustable UCA.

On my previous truck (highlander), had same issue with OEM tires. I was told by alignment/tire shop that this is called feathering and if all the alignment values are correct then this qualifies for manufacturing defect/replacement.

He told me that this usually happens on older vehicles where the shocks and other components are getting weaker, but if everything else is new or corrected for, then contact the manufacturer.
