Causes of slightly more worn inside and outside edges?
I replaced my tires after getting nearly 100,000 miles out of them (Yes that's correct...and the centers STILL had a bit of meat left!) and noticed that the edges though on pretty much all four tires were worn down near bald on the inside and outer sides. Is there any cause for this? I do have tein springs and a rear sway bar but those shouldn't affect the edges like that would it? The alignment has always been pretty good too, within spec.

what were your camber specs set at? Lowering the car should not have too much camber effect on the rear but it still may have been slightly altered?
Are you cornering hard ever? |

All four corners, under-inflated would be my initial guess.

I don't have the specs numbers on me but I know when I get an alignment check every so often, they are always in spec and if they are not, they get fixed. I do admittingly take some corners fast every so often but not all the time. Would fast corners wear the inside and outer edges out?

without proper inflation, pushing the car to its limits could put more stress on the tires in the wrong areas/ways.
Unless you have aftermarket camber arms/plates/bolts/shims to recorrect you could still have the camber knocked out spec. |

Yes, under-inflation is the textbook cause of simultaneous wear on both outer edges. Over-inflation on the other hand causes center wear.

Hard cornering wouldn't cause inside and outside edge wear? I'm just trying to solve this one and know for sure what caused it

Hard cornering is just one factor. Alignment and tire pressure are other factors. I think toe being off is the number 1 killer for tires, followed by camber...if we're just looking at alignment.

FWIW guys, my race tires, which I do drive on the street a bit, have the same kinda wear.
-1.5* camber wears out the inner edge, and racing kills the outer edge. OP, if you don't race teh car, it's either your inflation pressure or a very screwed up alignment lol

It must be the tire pressure then because I always made sure the alignment was in spec. It's lowered and has a rear sway bar but yeah, it was ALWAYS in spec, especially the rears. I never had an issue with them

So chances are if you got that many miles out of them, you don't corner hard enough to cause poor wear. How much tread was left in the center? It's common for the edges to wear first even if everything is correct. Especially on skinny/tall tires like on a Yaris. You can bump up your pressures a little, but with 100,000mi service life....... I think you are fine (I get around 15,000mi out of my all-seasons.... winter autoX )
