I posted up a thread here and received some excellent feedback on replacement tires.

My question is that following an alignment (after changing a-arm to SPL v2), my front camber has been set to -1.8 and it looks like the area that is worn down is no longer part of the contact patch on close examination (the white dust on the tire is from rolling onto the concrete driveway - it seemingly doesn't even touch most of the inside 2 inches of the tire anymore).

Do you feel it is safe to continue to run these Toyo R888 front tires?

 

I don't think it's safe. That is the weakest point in the tire now. If you were to emergency stop, the tires could tear apart right there.

 

Ya I would say that looks pretty unsafe. Are you sure your camber is only -1.8? That looks like quite a bit of camber wear

 

It may not touch sitting still, but under lateral loads and heavy accel/decel it would/will. Plus a blowout is much more likely from a pothole or other obstruction with cords showing like that. Replace them. Tires are cheaper than hospital bills and wrecked cars.

 

Thanks guys - just checking before I place the order - either the RE11s or the NT05s - sometime today.

 

That is just camber wear. A 2-tire swap is about $50. Do it now.

 

Wait, I can just swap left to right (given it's directional but not asymmetric)? Even with the little bit of cording?

 

I wouldn't.

 

I just did the same thing a few months back.

This should extend their use for you.

 

No. The tires have to come OFF the wheels. Then you get good tread on the inside. Doubt if the outside is even touching the ground.

 

Yes, I understand it has to come off the wheel. Just worried that I let it get so bad already - not sure the structural integrity is up to par and worried about highway speeds. I think for peace of mind I'll have to ditch them.

 

Smart move. Like I said, that part may not touch while the wheels are straight and still, but during cornering and lateral loads it will.

 

Their trash , and how did you wear them like that ? Not enough track time with them?

 

I can't tell you what to do, but I personally wouldn't risk it.

Not worth my life. Is it worth yours?

 

Yes swamping is an option.

With directional the rolling direction must be the same so they have to be unmounted.

With asymmetric the rolling direction does not matter, but the inside and outside markings must be inside and out. These you do not need to unmounted, just swap left and right.

No rotation/swap will save the tire at this point. It is pretty unsafe to run a tire that worn and not worth the risk to you or the Z.

 

just buy new ones and feel safe driving

 

I just did this last week as well. My insides are worn down to almost no tread on all 4, so i had them swapped and now wear is on the outside...should give me some more tire life.

 

fck NT05s. Cant wait to get them off my car

 

Flipping tires is a great way to extend tire life on symmetric directional tires. However, you don't want to wait until you have worn the tread down that far. Flip the tires when the inside still has an acceptable, and safe, tread thickness..

 

Whats wrong with them? I love the set i have
