2006 Impreza tire wear

kaotik78 · 07-04-2008, 09:13 AM

I've begun to notice the front tires on my Impreza are wearing excessively at 18k. Tire pressure was originally set to 44 psi at the dealer, I took it down to 35 and have kept it there ever since.

Should they be wearing out on the inside (camber out of adjustment) at only 18k? This is a first for me on a car and was concerned that this could be a intro to more maintence on this car down the road?

Or, do I have the incorrect psi for the tires that the car came with, potenzas, or is the camber out already, all my driving is highway.

Well 35psi is fine and is not causing the uneven wear. I doubt its camber, its more or less toe. 44psi is sort of high but its not gonna affect the inside of the tire, if anything the center of the tire would wear more.

Your gonna need to probably wait till that set of tires is shot and purchase new tires and have the car re-aligned. You can get an alignment now but its not gonna really do much because you already have uneven wear and its just gonna continue.

Thx for the input. 18k and the car's alignment is already out of adjustment? Is this a charachteristic of the car, that it will not hold an alignment for long?

No its not normal. You could have hit a large pothole, possibly curb which would knock the alignment out of spec. Maybe when you bought it new Subaru did not align it correctly, it happens.

I'd get it aligned ASAP. Just because you're getting tire wear and you're going to swap out the tires doesn't mean you should wait.

I think SubeDude81 got it right: TOE. Toe in (or out) is what eats tires far more often than camber. I have mine set to zero toe and I get very even tire wear, even running -3 degrees of camber in front.
