Steer tires starting to cup

Hey gang.

Just spent a lot of time reading through an older thread on here about cupping on the steers but everyone on there has been referring to outside shoulder cupping.

I have a set of R268 Bridgestone 295/80/22.5 heavy steers with about 82k miles on them so far and running at about 100 to 110 psi. Front axle components are all about 2 years old at most with shocks being a little over a year old. Well I parked the truck yesturday and noticed I'm stating to get random cupping on the INSIDE shoulder of my right steer. Left steer seems to still be perfectly round.

Truck has some centramatics but they are about 7 to 8 years old with about 500k miles on them. Checked front end components and nothing seems to appear bad. But I have been running pretty light weight these past comple weeks. Normally the truck will see 13 to 14k lbs on the front end on the regular, but lately I've been sitting around 11k lbs average and so bumps are pretty jolting with the heavy springs.

I guess what I'm wondering is, can a shock blow/be bad with out showing any leaks? Could alingment be affects by the bump? Or is it as simple as the centrimatics being bad and causing imbalance in the wheel?

These tires are extremely new and I'd rather not ruin the set so I'd like to get it fixed ASAP since the cupping showed up pretty fast.

Any ideas will help. I plan to stop into a speedco early tomorrow morning since they will be the only thing open at that time.

One thing to note. I am planning on going to a heavy duty aire ride up front since I haven't been hauling over 15k in quite some time and would like a smoother ride. So technically the front end will be getting rebuilt here very soon. Just trying to figure out if it's suspension related or ballence issue.

 

Yeah I should have specified truck. No this isn't a traditional tractor trailer. Dump truck in my profile pic was my old rig from like 5 years ago. It's a heavy spec t370 Kenworth with a single axle rear and one 10k lift axle. Lowest pressure I can run it is about 3k lbs when I have those light loads that just barely put the drive over 20k. Never actually scaled like that to see what the front end weighs at but could be around 10k in that case.

I'll skip the speedco visit and get my delivery done in the am. Got one short run over to Elkhart with some steel. If you guys know of a good suspension shop out that way, let me know

 

I was originally going to get continental HSR II but they were on a national backorder that that time. Hence why I went with Bridgestone. I plan to still get conti's next time around
