Tire issues

kidkotic2001

I took my car to a Nissan dealer because my rear tire (driver side) was leaking air slow, I wanted them to repair the tire. I was called in after a while to the car bay, I was told that the tire could not be replaced because they had found 3 nails in the tire and it was also pretty worn out instead of buying the stock yokohoma tires 245/45 r18 95w (Which was 660 A piece) I took the opportunity to get two new ones from a different location.

I took it to a tire shop (Martin Tire) and bought two Toyo proxes4 245/45zr18 100W. Cheaper and the guy told me they were a little better than my stock tires. I really do not know if that is true. So I was driving home and there is a long straight way so I decided to punch it (like Usual) but as soon as I got to about 80MPH the car started to swerve. Never felt like that before, I got home and looked at tires made sure they were installed properly right tire on the right left on the left. I noticed that my rear driver side tire was butterflied in. So I took it to Nissan the next day I told them what I was experiencing and they told me it was an Alignment. I paid 90 bucks for one and the issue still there I got it back and did the same thing hit 80MPH and it felt the same way. I was able to hit 100MPH without any issue before it never felt like it was going to swerve.

Can anybody tell me if its the tires or something else? I am going to take it back to Nissan to see what else it could be but I wanted to see if anyone else has experienced this.

Sounds like the new tire was damaged during installation. It is tough to do but it does happen.

Got any pics of this "butterflying"?

And I would take it up to any speed until you get the issue sorted, could have catastrophic failure and let loose.

Nissan corrected the butterfly effect with an alignment but the issue still there.

ChrisSlicks

It may not of been corrected completely. Please describe the butterfly effect in more detail or post a pic if you have it.

In for response. I have the same issue also. I just had 2 new rear Hankook installed and have swerving issues at 80+mph. I just thought it was because the tires needed to be broken in or something.

Brand new tires are very slippery for about 200 miles until properly scrubbed in. It could be as simple as having slippery new tires in the rear with grippy tires in the front.

Check pressures, get them scrubbed in by throwing it through a few freeway on ramps and report back.

Can't really see anything clearly in those pics. Can you zoom in some more?

Why do we get people complaining about poor handling cars after mismatching tires every two weeks or so?

kidkotic2001

I took closer pic of tires but when I try to upload them I get an error I think they are to big.

I am now wondering if its because I have two different set of tires. my front ones are the original stock Yokohomas and my back ones are the Toyo proxes 4.

I dont think that would make a difference I have done this in the past with my previous 350z and eclipse.

If it is the tire that was damaged when installing, You should take it back to Martin tire and get it replaced, as opposed to taking it to nissan.
Maybe you need to break the tires in, looking to get new tires, but I will replace all 4 and decrease the stagger as much as i can so that i dont have any potential problems. let us know how it goes.

kenchan

tires, especially rear tires if new, must be broken in first. if you use mis-match tires obviously it will have different bias especially in the wet.

drive around normally for 100miles and report back.

also SLOW DOWN!
