does this make sense to anyone (tires)

ok, on my tires, the inside fronts are wearing faster than the outsides, the rears are wearing even. i rotated the tires 5k miles ago so its time again but theres not much of a point in rotating front to back because the insides of the tires have less tred than the outsides.. being that i have directional tires and cannot cross rotate to even it out, i am planning on having my tires removed and remounted and balanced on the opposite sides..

this way the outside of the tires (which has a lot of tread left) will be on the sides. the part that is worn down isnt bald or anything, theres tread left, but imo it would probably be better to have more tread on the inside, especially since my coilovers are going to be installed on monday. what do you think?

I have the same problem on my car.

I bought a set of Continental ContiExtremeContacts in Sept. last year. This was a couple months after lowering my car. In Feb of this year, I replaced my rear driver's side wheel bearing and when I took it in for an alignment, I discovered that my front camber was way out of hand. The front tires were worn down alot on the insides and the rear tires were still in good shape but, worn evenly. I swapped the tires front/rear and then the rears (now in the front) began to wear on the inside.

The only way to even the front wear out is to remove the tires from th wheels and put the driver's side tire on the passenger side wheel and make the outter edge (not worn) replace the worn edge (inner edge). This is going to result in a tire that is bald on the outside and griping on the inside.

A set of those K-mac upper control arm bushing would fix this problem...

yea, thats exacty what im gonna do, but the way i see it... if my tires have that much wear on the inside, then the outside of the tire is giving you less traction anyway, so that should more or less make it the same swapping the tire sides... better in regards to the tread wear because they will have more tread on the inside now. im lowering my car monday, so i think im gonna have the shop do that too.

This is my theory, dont know if there is any truth to it....

I think its peoples driving habits, if you take corners faster or what not you get inner wear, even if your car is aligned. Also if you put new tires on and it begins to wear on the insides and you still get aligned after, the tire still sits more on the insides causing more wear. Its not correctable after it begins.
I have the same problem and I was thinking about demounting and swaping sides and remounting and balancing but I cant help but think that it could be dangerous because you dont really have any grip on the outer edge of the tire. this could result in a fu*ked up situation if you were to start doing some aggressive driving. Once again just my theory.

That inner tire wear is mainly attributed to negative camber.



Some negative camber is good but, too much will always result in excessive inner tire wear. This is why it is necessary to get adjustable parts for the front suspension after you lower the car. The OEM control arms are designed to be a specific length to accomdate the OEM ride height. Once you lower that ride height (lowering springs) you now push the wheel higher up into the wheel well and now the lower control arms are tiping the tire onto it's inner edge. The causes the tires the get hotter on this edge and in turn, you shave more rubber off all the time.

A camber adjustement kit would either allow you to change the length of the upper control arms (CPP control arms) to push the top of the tire out more or an adjustable control arm bushing would allow the angle of the upper arms to be higher or lower based on the adjustment of the bushing (K-mac bushings).

You really want this to happen:

Ditto

"That inner tire wear is mainly attributed to negative camber. " Yes I second that, but I have heard even if you get aligned to .01 negative camber and you do aggressive driving then it will result in the inners wearing alot faster. But yes aftermarket control arms would be the best fix, wish they weren't as pricey for the S4s.

i think they are pricey for any cars. but i think i would have some outer tire wear from hard cornering as well, i dont really do any hard cornering though, so that would explain that part.
