18"

Looking at the tires, there are different thread depths, most are deeper than
not.

Theres a few threads which are quite shallow, once those are gone is it time to change? I hope not, as the other threads look like they have a ways to go until theyre gone. Looks like the wear indicator may be just bellow the shallow thread.

Anyhow, thatd suck if that was the case as the tires to the eye would look like they still had plenty of life in them.

Any input would be appreciated.

 

you can try the penny method,

flip the coin so abe's head is towards the tire, and if you see his hair then it's time to change, or it's something like that...

I go by visual (not the best way), haha

 

are you saying it's wearing unevenly? Is there a patern to it? is it wearing more toward the center, one side or the other, etc?

 

no its just how the threads were designed, I'm actually very impressed with the wear pattern. . .considering we can't really rotate(besides side to side)
very even

 

I don't think the tires are meant to be rotated side to side since they are directional. I think there is no rotation for the oem wheels.

 

You can rotate them side to side, the Potenzas are clearly marked "outside" so as long you don't remount the tires with the outside on the inside you'll be fine

 

now i have to look, but I thought they were directional too... (so you can't rotate them side to side even though the potenza word is on the outside)

I guess you 'can' rotate them even though they are directional, but it'll probably wear out faster, and probably lose out on some of it's functionalities...

 

I want to know who is going to replace their 07S with a non staggered setup. Maybe 245 45 18 all around? What will this do to the VDC/ABS is the question.

 

^^ probably nothing, the staggered difference is so slight... that's my guess

 

Wei, those Potenzas aren't directional but have to be mounted with the wider tread lugs to the outside (hence the "outside" designation on the tire). They can be rotated side to side. BTW, directional tires will always have an arrow or arrows on the sidewall indicating forward rotation.

If you compromise with your new tire sizes, going a bit narrower in the rear and a bit wider in the front you should be able to use a single tire size all around on the staggered rims. If you just go narrower in the rear or wider in the front you may get poor wear in the outer treads on the tire that's too wide and poor wear on the inner treads on a too narrow tire.

I think you'd be better off finding cheaper tires (such as Kumhos) and stick with a staggered size. I'm looking to replace my rear tires in the next 5000 miles so I'm interested in what others have found as well
