Took it back to Martin Tire
 

I woke up today and instead of taking the car to Nissan I took it back to Martin Tire. They rebalanced tires and I took it for a spin but same issue, The manager at that location sent me to a "state of the art" location that can run the tire and do all types of test.

I got to the other Martin Tire and they did a lot of test to the two rear tires they found one that was out of round. They replaced it no problem I took a test drive after replacing it and it still there.

I have never had this problem before I did the same thing to my 350Z had to replace the rear tires because of a blow out. I did not have this swaying from left to right or right to left. I do not understand what is going on.

I will drive it for about 100 miles and see if that makes a difference, if not I will go ahead and probably buy the two front ones same brand as the back and see if that helps.

I will also slow down to our speed limit of 60MPH for the time being. :shakes head:

:tup:

you have the same exact problem right after they installed the new tire? well duh brah, it wasnt broken in yet. you cant slap on new tires and expect to be fine....

also having two dif brand or model tire front and rear isnt an issue as long as they are both in acceptable conditions.

Break them in!

doesnt matter.

Breaking in
 

So I guess I will break them in and see how it goes. I will post back later on about a week or two to let you all know whats up.

Update
 

So after 200 miles of breaking in tires I still had the same issue. I went back to the shop and we both agreed that it might be the Car not liking the Tries. We replaced the rear with some Falken 502 same stock size. They rebalanced them and put them right back. I immediately felt a difference I am able to do 80+ with no issues. I will be took car to work today to do further testing since I go up mountain and has nice curves that my car loves. After work going home the turns are tighter I will see if I see any swaying from left to right. I will update this again today and hopefully issue is fully resolved.

i had the same issue. i got a metal size of a quarter in my rear tire. i added air and it is leaking big time so it must be unpatchable. so i went to big o tire. they were right next to my house. and the guy suggest nitto nt850, asymetrical tires. i dunt know about tires so i just get it. its was $205 a piece. expensive, i know. anyways i need tire right away so i just say go ahead install it. still using stock yokohama in fronts.

so i thought im good, and then i drove it on freeway and it swerve going on straight line. i can feel its rear doing it, not the front. ok i thought maybe needed break in. i call and ask if it should be swerving on strait aways on the freeway. its even worse on a not so strait and in the freeway too. it feel like rear tires slide and jumpy. they say let it break in 1st so i said ok. and about 600 miles in it still doin it. so i call and he let me return and get different ones. so they priced the yokohama advan sport at $290 each. i was like ok. ill just do it. add $180 from original price i paid for the nittos. and hope it is worth it to pay to feel safe driving again.

then when installed, even brand new, it didnt swerve at all. so i dunt know what was wrong. is it the nitto 850 or is it diff type tires on front and rear to causes the swerves?

now even tho i paid so much for stock tires im happy its safe. before i was driving with one hand on the wheel, when it was on those tires i drive 2 hand on wheel to turn wheel back to other way when it swervy. now comfort of driving is back even tho i overpaid. next time i aint goin to big o tires even tho they had let me return the bad tires. good service by them but way too pricey. soon ill need replaced the fronts so now im doing my homework on some tires.

1. you have mismatched tires...they will always feel off...the faster you go the more swirly they will get, and dangerous!

2. You bought low performance tires that are softer than the stock tires, they are going to feel less planted.

3. Next time do some research on tirerack.com and spend some money on the right tires (all 4 the same brand/model for your sports car.

yea thanks. the faster i went the easier it swerves. now i know mismatch is not ok. i have been looking at tirerack.com and other sites

It doesn't matter if you break it in or not. Breaking it in will help a bit, but the issue still persists. It doesn't inspire confidence at all. Just get the same tires. I put hankooks in the rear and I have Advan sport in the front (driven for 3,000 miles).

I told ya, see #20...

Going that fast on brand new tires is suicidal, they need to be broke in first!

I had this problem when swapping my stock rears out with some hankooks. Found out that the stock bridgestones are directional and the hankooks have to be installed with a certain side out. Car was dangerous at highway speeds. Bought matching hankook fronts and have been happy ever since.
