Wheel alignment check dusty floor

[Jason]

Procrastination wins again! Garage floor was really dusty, but noticed this on the tires. Maybe I need an alignment check, what do you think? Tires have 10,000 miles

Here is something you can review prior to having an alignment.

How are your tire pressures ?

What kind of driving are you doing ?

Cornering with lower pressure can wear the edges a bit.

I run 28 psi.

Mostly highway. Just finished 2500 mile trip from the western meet

i took the winding mountain roads a little quick maybe that scrubbed them

As Scott posted lower air pressure wears outside of tires over inflated wears the center of tires might try increasing pressure one to two pounds

Thanks , Worth a try if the alignment checks out.

I run mine at about 34 psi. 

But most of my driving is straight highway. 

Not many curves in the Q.E.2.....

looks like toe is off

[Scott S.]

More like camber.... Both sides look fairly equal.

hmmm what size? I’m running 245/60/R15 on all four.

Ya something not right on the suspension as the outside front has slight cupping.

Cool thanks, I’ll take some tire tread depth readings to see if the outsides are wearing more

Hey Jason, just a quick question.

Are you running 8" wheels on the front ?

No still on the 7 inch. Would like to go to the 8 inch though since the range for those tires is 7 to 8.5 wide

[Scott S.]

That's the main reason I went with the 225's on the front..... They're on 7" wheels.

Putting a 245 on a 7" wheel "balloons" the sidewall, that might cause more flex on it when cornering. And that could be a factor on you wear pattern.

Just a thought.

Yes agreed 8 inch would be better.  Just got back from the alignment shop and the total toe was 0.01” so they set it to 0.10 total
