Slip light and handle issue with new tires... help??
Hey guys,
I just got new tires installed on the rear only and when i was going down the freeway it was pulling toward the right. It didnt feel right, I felt like the car is about to fish-tail. Just in regular turns I see "Slip" light coming on.
The tire presure is good and I'm sure my alignment was good at least till before I got my tires installed. i got different tire brand then the front.
My question are:
- can this be an result for having two differnt tires? I have stock Potenza in the front and kumho on the back.
- Is it possible that my ABS/VDC or any susp conponent is jacked-up?
- Can this be an result of improper tire balance?
I dont hear any noice or feel vibration when braking or in turns but I do feel like my rear is kinda sliding/ gliding without the slide or glide. I will go back to the tire shop and ask them to check the balance again but my understanding is that when the balacing is not done right, you feel vibration... any advice?
Thanks in advance!

Yeah its stock size 225/45/18... this is why I'm kinda confused. Once thing I forgot to mention is that I took hard turn with VDC off since I was going to change my rear tires I just thought it would be fun lil drift on a right turn. Nothing serious, just a fishtailing right turn. Can this be an issue? I hardly ever drift since im always stuck in traffic for the past 6 years... i got Kumho ecsta LX platinum since it has 600 treadwear. Is there way to reset the VDC or something?

New tires are slippery. They are coated with a release agent during manufacturing that must be scuffed off the tire in order for them to perform at max potential.
There are also inherent problems with mixing tire brands and models front to rear. they may not have the same expected levels of traction.
All things considered, I AM concerned about your report that the car is pulling to the right, especially since it was the rears replaced. I'd have the tire shop check it out first.

Your tire sizes are fine.
I’ll bet your problem is based in what Dave describes. Your new tires are “greasy.” And that’s why they are slipping around. I’ve experienced the same problem. After just a few miles of driving, the “grease layer” is gone, the tread irregularities will wear to “even,” and your new tires will feel normal.
The only other explanation would be a defective tire (and I’ve had that happen as well).
Let us know how this is resolved (post back to this thread).

I have a question about your comment “it was pulling toward the right.”
Does that happen only when applying the brakes and when slowing, or does it occur when driving at a constant speed?

I think you guys are right about the tire being greasy... after 50miles of drive I dont see sleeping lights however it is still pulling toward the right. I went back to the tire place and didnt really found anything wrong with the tires (balance or presure) on all 4 tires. I think this is alignment issue... hoping thats it. Im getting alignment done this thursday so I'll let you guys know if that fix the issue.

It could be a conicity issue. Every tire is somewhat cone-shaped and has an inherent pull to either the right or left. Since you have no way of knowing what conicity your tires have when you buy them, you might have ended up with two that have high values in opposite directions, which is causing a large pull to one direction at the rear. Try switching them left to right and see if the car pulls the other way. If it does, then it is just due to their conicity and you can't do much about it. It will change with wear, and since the rear has a good amount of camber, that wear will cause them to achieve a neutral pull at some point.
If your previous tires were the OE ones that came with the car, they will have been matched by Nissan so that their conicity values mostly cancelled each other, but produced a slight pull to the left. This is so that your vehicle drives straight on the inside lane of the highway, which usually has a 1-1.5 deg crown. All OEs do this, but with trade tires it's luck of the draw.

When you mount new tires, it’s wise to do an alignment (that is something I always do). That adds additional expense, but summer-performance tires are costly and wear quickly (and wear very quickly when you have a faulty alignment).
If you detect a right-pull on the expressway, it could be simply the crown in the roadway combined with the grease and irregular tread on your new tires. If the symptom lasts more than a hundred miles or more, then there is something else wrong (and probably the alignment). The other possibility could be a bad tire (it happens).
Please keep us posted on your problem and solution.

I'm leaning toward a "bad tire" too. If it was an alignment problem, then in all likelyhood it would have done it with the old tire. The thing that concerns me is that we're talking about the rear and these kind of problem typically appear on the front.
A "bad" tire is one that has some internal defect that causes the tire to pull one direction or another - typically called "radial pull" because it appears in biased radial tires.

I'd recommend switching the tires left to right and driving on the same stretch of road to see if it pulls the other way. If it does, you likely have high axle conicity. If it doesn't, you could have high plysteer (does not change with direction). Whatever the case, if it's not alignment related, there's not much you can do about it!

That’s my point, and Dave mentions the same.
---------------------
So… that takes us to your second point/question: “Also, what is a "bad tire" Spike?”
Well… the answer is simply that: a bad tire. The tire (due to a manufacturing defect) won’t track in a straight line. Some of these always go right, others always go left, and some wiggle back and forth, right to left and left to right. See Dave’s message above for a good definition. Mercifully the occurrence is rare, but it does happen. Tire manufacturing is by no means a perfect science (consider the many tire recalls occurring over the past years).

Re> “While it could be alignment, it is unlikely that the alignment suddenly changed the day he got new tires mounted.”

Conicity is a manufacturing variation, and all tires made (at least at Bridgestone) are screened for conicity before leaving the plant. However, you can have two tires that measured within limits when leaving the plant that, when put on the same car, can have an adverse effect (bingo - pulling on the highway!!)
Spike, you should know better than to argue with a tire engineer. This is my job - I'm even in the Tire/Vehicle Dynamics department who work with OEs to do studies on this exact stuff. If you don't understand it, look up the SAE papers on conicity and other tire topics; you'll learn a lot. All of this is information is out there

You're wrong again - it's not subtle at all. I wouldn't be wasting my time arguing this point if it wasn't a possible cause. What part of "I know way more about this topic than you can imagine" do you not understand? Stop trying to weasle your way out of being wrong again Spike
Oh p.s. OP - it is not a balance issue.
