Need Help: Uneven Tire Wear

[RPC]

Relevant info:
- 2008 V8 SR5 W4D w/100,8xx mi
- Tires installed at 49,964 mi, SpiderTrax installed whole time
- 99% of miles are freeway

Would insufficient rotation frequency cause this kind of wear? How could all four corners experience higher outer wear than inner wear?

I’m getting new tires installed next week and I want to avoid this uneven wear on my next set, but have no idea what’s causing it, so don’t know what to do differently.

Edit: image from imgur unnecessarily huge, apologies

Improper alignment due to adjustment, worn parts, etc., or excessive high speed cornering.

Any cupping in the tires? How old are your shocks?

Got alignment addressed but wasn’t terrible. Truck is almost 10 years old w/100K on the dial but has been we’ll cared for. Lastly, there are a couple of corners on my commute I like to dig into hut otherwise I’m a pretty conservative driver.

No cupping to be seen. Shocks are original.

It’s crazy- I expected to hear that camber was off all the way around the way the outside of all tires were overly worn, but nothing of the sort.

Any additional thoughts on this? What could I have looked at on my truck to determine cause?

Again, about to drop $800 on all new tires and would very much like to avoid doing the same to them...

tire pressure plays a role too.
32 to 34 psi is what i run. also driving habits, and worn suspension can cause all sorts of things.

Appreciate the response. I check my tire pressure regularly (34 PSI is my target) and I’m a pretty conservative driver.

What suspension components should I have checked out?

Tie rods, control arm bushings, wheel bearings, etc...

Good copy, will have these points checked out tomorrow while they’re swapping tires.
