Re: Uneven tire wear
lug nuts shouldnt matter if the size heights are different.. just matters that they fit properly and secure the wheel to the hub.
have you pulled the lugs off to verify they are different sizes?
could be one or two have loosened up and your just seeing the height difference.
you can check if your hubs are bad by lifting the front up and grabbing a tire at the 12 and 6 oclock position and try lifting up and down. you might need a 2x4 or something to help lift the tire up if its heavy.
iirc.. if you get any play more than 1/4 of an inch, the hub is bad... but i think the general rule around here is if you get any movement at all, just replace the hub(s).
If you are just worried about the lug nuts, i would simply buy replacement ones. maybe the previous owner broke a stud, and the original lug wouldnt fit on the new stud, so they put on one that was longer...

Re: Uneven tire wear
Sorry I wasn't very clear. I meant the tire tread lugs. One is high, the next is low, next is high, etc.
Thanks, I will check the hubs as you said.
But what does this tread wear indicate?
Thanks

Re: Uneven tire wear
what tread wear?
where is the worn down area at?? inside of tire? middle of tire or outter edge?
if it is on the edges, i would say possible alignment.
inside is over inflation.
both sides i would say maybe under inflation
i think for a worn hub, you would be seeing inside wear.. but maybe im wrong on that.

Re: Uneven tire wear
Ive got the same issue with my cognito level with 37 Stts with the front passenger tire wearing way premature compared to rest. Have had alignment checked three times and it is dead accurate. I get wear on outside lugs and 1st center traction zone closest to the outside lugs. all the rest of the tires are showing perfect wear. I cant figure it out too, unless its just normal wear for the front passenger tire?

Exactly what I have. But it's not just that it's worn down more on the outside, EVERY OTHER lug (alternating) on the outside row of lugs is worn down more. Weird. Any ideas?

Re: Uneven tire wear
Unless you personally know the guy doing your current alignments & verify he's more than qualified- I'd go get an alignment from another shop, preferibly a place that works on big trucks on a daily basis.
A good shop wouldn't have you asking these questions...
I dont remember how many shops I went through before I found a really good one.

Re: Uneven tire wear
I was hoping to get an answer here so I know if the alignment guy is pulling my chain or not...

I've got the same thing...every other lug on the outside tread is worn lower.
37" BFG MT KM2
Cognito UCA, pitman/idler arm kit
Cognito tie rods
I just found out though that I've got a lot of play in the front wheels and that my tie rods need replaced. Since I've just recently noticed the uneven tread i'm assuming it's due to the tie rods getting worn out. I just ordered some Kryptonites, we'll see if that evens things out any.

Re: Uneven tire wear
Sounds like your ball joints and possibly your hub bearings too.
