shoulder wear on tires

ok I have a 2012 tundra that rides on 255/70 R18, and I am getting a ton of shoulder wear. I have researched and found that year you could get the truck with 255 or 275. But the weight of the truck is whats causing the truck to ride on the shoulders of the tire. so the question is with all the tire options out there what should I go with to keep this from happening on the next set?

I am no expert on tires but I do know its not right.

 

Your problem is not tires. It is out of alignment. Depending on which shoulder your talking about, it is either positive or negative camber. Go get yourself an alignment.

 

I have had 7 alignments. its the outside shoulder on both front tires. If you look at the tires you can see that the shoulders are sitting on the ground. The OEM tires only lasted 25k miles and these are looking to last maybe 35K(60K) tires.

Btw Great season for yall.

 

Do you have a lift? Have you gotten a printout of your alignment specs after? @jberry813 might be able to help you.

It was a good season. Doesn't even matter that they lost in the end. Just proud they made it.

 

I don't have a lift but am thinking about getting a leveling kit for the front. I have receved print outs after the alignments. To the untrained eye,they look spot on.

 

Do you corner aggressively? From someone else's perspective....many people don't drive as aggressively as they think they do. lol And what tire pressure are they set to?

 

its the outside shoulder. The inside still looks new.
last tire alignment was a couple weeks ago. I will have to upload the sheet on Monday.

I am running 50 psi in the tire right now. Started off at 32 OEM spec and moved to 40 then to 50.

 

Outside edge wear can be from the following:
Alignment out of spec (sounds like you can probably rule that out)
Air pressure too low (but it usually effects inside too, and you say you're aired up)
Aggressive cornering causing the tire to tuck/roll under in turns. I'm guessing this can be a good part of it, skinny tire on a heavy ass truck.

 

they are they oem shocks with only 50k miles on the truck.

 

Thank you for the information and I will get the alignment sheet posted on Monday. But if I wanted to go with a Wider tire what should I go with?

 

If you don't need the rear end to articulate as much how about a rear sway bar? I know this helped out tremendously on my previous 2x truck.

 

This^^^this will tell us everything we need to know.

 

Food for thought, I had fords eating up outside of tires. I put michelin's on the truck, no newalignment and they wore perfect.
Anyone running Michelin's?

 

Love asking the alignment shop to align to a certain spec and getting told there must be something wrong component wise if I have tire wear. So I said if you can't get the camber between 0 and negative 1 I can take it somewhere else....

 

This may not be of any relevance but check your tire pressure. Aftermarket tires may require different pressure than what is printed on the inside of your door.

 

You have tire wear indicating excessive positive camber. You have a computer printout indicating rainbows, unicorns and puppies. If you are getting it aligned at the same shop, you might consider trying a different one. Either that or specifically ask them to dial in some negative camber, assuming there is room left in the adjustment.

Adding a lift will only make this worse with the stock UCAs.

 

This was my sheet I paid $74 for....

 

Ha, should have just checked it, saw in spec and gave the truck back at no charge.

 

Not sure about the newer stuff, but my 02 Tundra has always eaten front tires! Been checked 8 ways to Sunday and my best guess is the fact that I have a loaded truck, lots of windy roads, and up intil recently they would chip seal the roads which was sort of like driving on sandpaper. Decent tires seem to last about 35k regardless if they are P rated or LT's. If you are highway driving it and it is eating the tires I would suspect something is wrong, if like me, about 85% of the driving is non highway, that just seems to be the way it goes at least with the 1st gens.

 

So it's been 1000 miles since I put the new rims and tires on. I am getting the same old shoulder wear. I went back to the alignment shop that charged me $75 to tell me my alignment was fine and told them to fix it. After some argument they agreed to dial in some negative camber. When I went to pick it up, they said the factory specs for my new tires (275/65/18) had a wider band for negative camber. So they moved it. I am attaching my old and new alignment sheets.

 

Forgot to say they tried to charge me for another alignment. I told them I paid once and you didn't do what I asked, so why should I pay now. They no charged it.

 

Shit, as much money as you've given them, I'm surprised they didn't just start giving them for free.

 

Did Clint and Saturn draft figure out the issue? My Michellins have this front tire outside wear and i think its cornering stress. Im tryingnto find tires that will be able to defend this. Any suggestions?

 

I think you should invest that saved $74 into a new pair of sneakers.

 

Did you ever figure out why the tire was wearing more quickly than the others? Mine does the same thing even though it is in alignment (even after adjusting parameters) and with consistent rotations. Thank you in advance.

 

I wonder if he ever got new sneakers
