So my front right tires is wearing out on both edges of the tire...Front end alignment needed? I put the spare on and on either edge of the tire is rubbing on the road more so than the rest of the tire like the camber is off, but both edges are wearing? I took off my old F1 tire and one half of the tire was worn out more so than the other half. Also the car pulls to the right. Driver side tire is fine, no excessive wear.

Here is a picture of the spare i put on and drove about 80 miles. You can see the wear (dark line) on the edge of the tire. It is like that on the other side of the tire.



This picture shows both side of my old tire worn out pretty bad. Almost bald on the edges.

Is your car lowered? I know when you lower the car it messes with the geometry. My alignments always seem horrible, theres always alot of negative camber so the inside of the tires wears faster. You cant correct it enough to compensate with the stock suspension. I know you can get camber plates for some cars bit i havent seen any for the S4. You can get some stern adjustable upper controll arms that will let you fix it but only if you have the time/ know how.

I sould find some pictures of my falken RT-615's the day i got my snow tires. You could see the wire belting in the tire it was really bad.

 

Stock ride height and stock suspension

 

i think its ur toe angle...
wouldnt that cause it to wear like that on both sides??

 

Excessive toe and/or camber would only cause one edge to wear at a time.
Looks like an underinflated tire or a bad outer tie rod letting the tire skate side to side while going straight.
excessive toe in = worn outer edge and causes feathering
excessive toe out = worn inner edge and causes feathering
excessive negative camber = worn inner edge
excessive positive camber = worn outer edge
overinflation = worn middle
underinflation = worn on both outside edges
Caster isn't a tire wear angle so it can't be that.

 

yeah i taught bout underinflation but it looks way too far on the edge to be that (IMO)
but who knows maybe thats the case....

 

Either way there are one or two things it can be, save your tires and get that thing on an alignment rack asap. It would prove valuable to get a printout and have them explain it to you before you leave to see how many degrees you are out of spec and into the red. Finally ask them what adjustment they did to get it to show green.
