This Wednesday is inspection day and I plan on having a 5-tire rotation and alignment as the front tires are cupping a bit, about 5500 miles. I have the RC 2" leveling spacers in my '05. The RC installation instructions include specific specs for the alignment. The 2 shops that have done alignments for me after lift and after the Rough Country UCA install used the preloaded software to align the truck. The previous spec sheet is all green but still remains outside of the RC specs. Should I even need be concerned, or should I insist they use the specs I provide? Thanks

I wouldn't rule that out. I'll double check tomorrow, but I think they are like 40ish front and 38ish rear. LT275/70r18 Cooper Adventure A/T
Cupping usually always related to rim distortion or tire balance issues…
With the 2” spacers it’s easy enough to get everything back in green.
The RC specs are essentially an expanded range of the OE specs to compensate for the changed components.
I have the RC 3” spacers and my caster is in the red out of the oe range but within the RC provided specs… No noted tire wear with 10k plus miles since alignment…

Ok, the air pressure was 41 front/39 rear. Now at 39 each for rotation's sake tomorrow. These guys offer Road Force balancing so I will do that as well. All of the tires are at 13/32nds across, and the fronts are 12/32nds at the outer channel. Closer to 6000 miles since the last alignment and 14k since purchase,16/32nds new. As far as the alignment goes here are the previous alignment stats and the RC specs. Should I insist on them using the RC specs?

I think the specs are good enough….could be some carryover wear before the recent alignment…
Once the tires wear funny even with a good alignment it won’t fix them….

Thanks for the replies, I ended up getting the Road Force balance done. Shes smooth as silk now. They also did the alignment to my specs. So far it feels better on the highway so no complaints. As far as the "cupping" as I described, was actually termed Heel-Toe wear. And the Toe was actually way out before the tech made any changes.
