Default Year old Dunlops gone to hell

Got these through Luke at the Tire Rack just over a year ago. Great service by Luke all around by the way. Took the car to be inspected today (huge process in PA ) and they call me telling me I need three new tires. Of course this gets into a big back and forth "I know cars and tires and mine are fine" "Your steel belts are showing through" blah blah blah until I get enough and leave work to go verify. Sure enough the inside shoulder is worn down on both front tires with 6/32 of good tread left! . Now these were great tires (Dunlop SPsport5000 ASY) in wet, snow, and dry. Really could not have been happier from an all season stand point. I am however mystified as to how a stock suspended car could crap out it's tires like that so quickly and completely when I keep up on the maintenance. When it's time for a service I take it in and it gets done, including alignments. I've owned lowered vehicles before that never gave me a problem like this. The tires are size 225/50 on the stock wheel but I know many of you are running this set up......anyone else have this problem with the slightly oversized tire?

*edit* I need 3 because one is new two are worn so the last one gets sacraficed to save the differential.....yay....AWD + tire problems =

How often are you rotating your tires and checking tire pressure? I rotate my tires every 3K.

And the only question that matters... How much toe do you have? Your alignment wears tires not the size of the tires or what height your car is at. Tire pressure can contribute to wear but if the inner part of your tire is on the belts and the outer part is at 6/32nds then your alignment is truly and utterly borked and it has nothing to do with your tires or your springs.

Homer, not as often as you are.....maybe I should increase the frequency.

Uncle Scotty, yes the car will be aligned when the new tires are put on

Phil, I generally run the tires a little high on pressure to reduce sidewall flex. This feels much better in cornering and accelerating. I picked it up while autocrossing (not on these tires of course) and have done it ever since. The alignment will of course be done I just don't see what happened. No accidents or rally racing. No potholes or raised manhole covers or any of that. It's all smooth road and freeway with one train track crossing between here and anywhere I go including work. Just wondering about the size issue, glad to hear that has little or nothing to do with it.

Phil - Does low pressure wear harder or does high pressure?

low tire pressures wear tires on the outside while high pressure takes more from the middle of the tread...i think

Default Sound like an alignment problem

Check you air pressures, maybe bump them up a couple of PSI. I would check your alignment, The Toe and Camber are the big ones that tend to wear the inner edges of the tires.

Thanks John, I'm pretty fanatical about keeping the pressure correct because I have a sickness that makes me try and get good gas mileage from sporty cars and correct to slightly high pressure helps with that. It's currently anywhere between 34 and 36 PSI on 225/50 16 Dunlop Sp5000s. I am taking it to a decent place to get it aligned and I will be sure to mention the problem. I see other guys having this problem the more I look at the tire forum. I could probably rotate more often as well. I can't find any information advising how often to get an alignment. Once a year??
