Substantial uneven tread wear on my new 33's?

[grenda]

Bought a brand new set of maxis bighorn 33x12.5-15 and put them on my 94 runner and also got new rear shocks, front shocks are solid. However all four tires are wearing substantially more on the outside of the tread? Not sure what to think? Any ideas guys?

My first thought would be an alignment. But the rears are wearing on the outside too? I don't think the rear has any alignment adjustments so I would look into all rubber components in the suspension. Check the joints for the links in the rear suspension and front upper and lower control arm bushings.

Are all the tires balanced?

Got pictures? How many miles on them currently? Have you been rotating them?

Front definitely sounds like an alignment.

The rear though.. Thats tricky. Agree with SV check all bushings. Also check wheel bearings and make sure you axle isnt bent....

well my first thought is that the problem is you bought maxis tires hahahah i kid i kid

anything wrong in your steering? loose or worn out parts of the rack and such can cause this sort of thing
does not explain the rear.....

my only other thought is that you are running the wrong PSI...

good luck get pictures and more details and report back

When you say "outside", do you mean outside relative to the truck, or outside relative to the tires? If all four tires are wearing on both shoulders, then you're running too low a PSI. If they're just wearing on the shoulders farthest from the truck, then it's an alignment issue. That's easily dealt with in front, but there's nothing adjustable in the rear, and you might have a bent axle like Hyde suggested. How are the rear axle seals?
