tire scalloping from blown suspension or lift and no UCA's?

I had a bad set of blown fox coil overs that i thought was the issue causing the scalloping on my tires so they were replaced with billies W/ 881's and rotated the rear tires up front that had good even wear, got the truck aligned and they never said anything was off or out of spec and it drove decent

300 or less miles later the good rear tires are now scalloped exactly the same. so i'm thinking its possibly from bad alignment and i bought some JBA UCA's and they got here today. ill have em installed and aligned soon

so has anyone experienced this kind of tire wear and was it fixed with new UCA's and a proper alignment?

also will the tires begin to wear evenly again (ill be rotating them regularly to try and help get em worn normal again) or are they jacked off permanently?

 

The scallops your refer to will never even out unfortunately.

 

bummer hopefully i'm calling it the correct term.

basically each tread nob is like half worn down, and has a high spot and a low spot. also on the edge of each tread nob looks like its getting chewed up and small chunks are coming off.

after googling it is more commonly called cupping i guess.

ill take a picture tomorrow. but here is the closest picture i could find online.

im also not just curions if it will wear evenly again but what cause it, since i have put new coil overs on it. was it not having high caster UCA's with my lift that did it?

im not trying to destroy a brand new set of tires since i will be replacing this summer. im hoping MY JBA's will fix it

 

That’s caused by alignment. When you get the truck aligned make sure the truck has 0 degrees of camber and toe. I don’t think that will ever even out but I’m really not sure so don’t quote me on that lol

also apparently a burnout will fix them if there on the rear lol

 

I had some cupping front and rear when I was running 5100's after adding a bunch of weight. The tires have smoothed out for the most part now that I've got an appropriate suspension setup. Definitely check your alignment but you may be under-damped still depending on your weight and setup.

 

I had the same problem years ago until I changed out to adjustable UCA's, problem solved.
