05LegacyGTGa Posted November 16, 2015 Share Posted November 16, 2015 I just noticed my front tires wearing funny. They are wearing on the outside and inside edges. I've kept the tire pressure good since I've had it. Could it be the alignment? Or something else in the front end? Link to comment Share on other sites More sharing options...

whitetiger Posted November 16, 2015 Share Posted November 16, 2015 things we will need to know to help you what is your tire pressure? what are your alignment specs at currently? Have you confirmed there is no play in any ball joints, tie rods, bushings, or any other suspension issue that would affect wheel stability?

05LegacyGTGa Posted November 16, 2015 Author Share Posted November 16, 2015 I've kept them at 33 psi. Not sure of current specs, I bought the car about 2 months ago. And I haven't done a full check of everything under the front end. It doesn't seem to pull at all and is smooth and everything while driving.

JmP6889928 Posted November 16, 2015 Share Posted November 16, 2015 40 psi is about the minimum to run these at. What happens at 33 is that the center of the tread is bowed inwards (as the tire company wants you to run it because it's soft and squishy that way and wears the edges off as you have now) and 40+ brings the center of the tread up so the tire is flat across the tread surface. Increase your tire pressure for a while although you have already done quite a bit of damage. You'll get far better mileage, the car will handle better, and now, you'll hear more noise because of the wear. On new tires, it makes the actually quieter because you're running on the center of the tread rather than the edges. You can bring the tires back somewhat by doing this, but it will take a while.

05LegacyGTGa Posted November 17, 2015 Author Share Posted November 17, 2015 Well crap. Thanks for the info! I always try to find a happy medium with what the tire says and what the door sticker on the car says. Should I try around 42? Link to comment Share on other sites More sharing options...
JmP6889928 Posted November 19, 2015 Share Posted November 19, 2015 I generally run 44 in front and 42 in the rear-but I only drive my car in the spring, summer, fall-no winter. It depends on how you want it to handle and ride. Obviously more pressure makes it stiffer and you feel the small bumps more, but the tires will wear a lot more evenly.

Slow Scoobie Posted November 19, 2015 Share Posted November 19, 2015 Tire wear like that can be from under inflation, driving habits, alignment and worn suspension/steering components. Most commonly its under inflation in that situation though. Link to comment Share on other sites More sharing options...
Max Capacity Posted November 19, 2015 Share Posted November 19, 2015 I'm thinking that's a tierod end problem. Take it to a good alignment shop.

Most commonly its under inflation in that situation though. Driving the snot out of a car that has a fair amount of body roll will do this, especially if there isn't much/enough static/dynamic camber.

rmoore5 Posted November 19, 2015 Share Posted November 19, 2015 I vote ball joints. The camber goes to extremes when turning, but can be set to spec in a straight line. Link to comment Share on other sites More sharing options...
Heticor Posted November 19, 2015 Share Posted November 19, 2015 I have the same issue, I took the car to alignment two times, every thing is between specification and not wear on the suspension parts, however the tires wears on the shoulder. My brother in love have a new imperesa and also wear the tires in the same way. I though is defect from Subaru. However could be tire pressure, I keep the pressure at 32 PSI on all the tires.

quick4dr Posted November 19, 2015 Share Posted November 19, 2015 38psi front 36 rear is happy for my Toyo 265/40/17 wear is dead even, and for winter my Dunlop 225/45/17 I run same thing, if really really icey ill drop down a few psi approx. 2in drop all around, max caster I think like 6.2 or something like that, -1 camber front, -1 camber rear 0 toe Link to comment Share on other sites More sharing options...

Imperesa's have rear camber issues from the factory. I had a Ski buddy have a camber kit installed on his newer one last March. OP, Take the car to a god alignment shop they are the experts, not us from our computers. Yea, I guess ball joint can cause the outside to wear too, by looking at my old snow tires. If your car needs ball joints be ready to replace the spindles/knuckles. It sometimes works out cheaper labor wise if they crack the knuckle or break the pinch bolt. 305,600miles 5/2012 ej257 short block, 8/2011 installed VF52 turbo, @20.8psi, 280whp, 300ftlbs. (SOLD).

covertrussian Posted November 19, 2015 Share Posted November 19, 2015 33psi is 2psi down, factory calls for 35psi front and 33psi rear. I personally ran 36 front 34psi rear for a while and tire wear was fine, now days I run 42/40psi for better winter gas mileage. 05 LGT 16G 14psi 290whp/30mpg (SOLD) 12 OBP Stock 130whp/27mpg@87 Oct 00 G20t GT28r 10psi 250whp/36mpg 22 Ascent STOCK Link to comment Share on other sites More sharing options...
arani rey Posted November 20, 2015 Share Posted November 20, 2015 If you're running the PSI listed on the door placard you should have even tire wear. Those tires just look like they've been used to corner a lot. I don't see any chunks torn like they were used for track or autox however. I wish I had my WRX with me today to take my own picture, but after a whole summer of track days the tires basically look like this one I found. (Not enough negative camber is the source of the problem here) Link to comment Share on other sites More sharing options...

05LegacyGTGa Posted November 20, 2015 Author Share Posted November 20, 2015 It's never been on the track. And I'm not hard on it at all unless someone pisses me off ha. I'll try to get up under the front and check things out. Eventually I'll get it to an alignment place. Funds are tight but maybe I can find a place that does a check for free or something. Thanks everyone! Link to comment Share on other sites More sharing options...
JmP6889928 Posted November 22, 2015 Share Posted November 22, 2015 OK...everyone has weighed in with suggestions on suspension, alignment, and all of the other things. The front tires are worn on the inside and the outside almost identically, which indicates low tire pressure/running the tires on their outside and inside shoulders when going down the road. Bump the pressure up and see how it makes a difference. It costs nothing to do, and you'll see and feel an immediate difference. If you decide then to go for alignment, at least you'll be wearing the tires in the middle of the tread rather than on the edges. I used to see cars like this all the time. It was about 90% of the time due to low tire pressure (most people want their car to ride like it's on a cloud <NOT my words>) so the tire joints always put 32-35 in them. Always is a bad idea. Try them at 42 front and 40 rear and you'll immediately feel a difference and most likely the tires will be noisier. After a couple of weeks at that pressure, you'll begin to hear them quiet down a bit and most likely they'll continue to be quieter. Link to comment Share on other sites More sharing options...
