Bad tire wear. What should i check first?

[LagunaVert]

I took my wheels of to give them a good cleaning the other day and noticed that my front passenger side tire is almost bald on the inside edge. The drivers side is wearing the same way but no where near as bad. Where should i start in my search to fix said problem?

When was the last time you got it aligned? Any replacement of CAB or CA? If your car is really lowered, then camber plates will help with that.

Sorry, forgot to include that info. Car is not lowered. I replaced the CAB and CAs bout 3 months ago. When I took it to get inspected my mechanic said it didn't need an alignment. I guess i should probably take it to get an alignment.

Could it have been worn before you got it?

Did you get the M3 CAB or stockers?

Did you replace the tierods too?

Nah all the tires are less then a year old with less then 3k miles on them. I went with stock CAB and the tie rods were replaced withing the past year. I have a new set that i will probably have put on when i get it aligned.

You can check the alignment with a set of toe plates. You can buy them for $60, or make your own for basically nothing. All you need is a pair of tape measures, two flat plates around 24x6" (you just have to be able to slap them on the side of the tires, so this is not a precise measurement as long as they are the same size). You want about an eighth inch of total toe in.

Get your toe aligned straight,

my camber is ridiculous and the best information I have had is to get the toe fixed to maximize tire life
