Different tires being used at the same time

[zoso]

A while back i noticed that the POS placed that fixed up my car for the dealer put on 2 Toyo Tires, 1 Continental and one Good year (toyo's are not on the back the other 2 are on the front)

Could there be any problems caused by this, as since i rotated my tires and put the Continental and good year in front because the threads look better, i get a slightly rougher ride and more road noise is this from the mismatched tires, or just normal because of the type of tires?

You need all four tires to match -- not only should be they be the same kind of tire, they should all have similar wear. Otherwise your run the risk of different wheels gripping differently when stopping and steering. (At the very least the fronts should match each other as should the rears, and the tires with better traction should be on the back).

One thing we discovered that is very bad is running directional tires on the front and non-directional tires on the back. This causes the car to spin out quite easily in wet conditions, as the front will grip much better than the back, causing the back to kick out. This happened twice to my uncle in one day on his drive back from work.

How did you ever end up with 3 different brands of tires on your car??

I say it's definitely bad to have different tires on the same axle (different left and right). This can result in premature wear of suspension components/wheel hub.

I would try to avoid having 2 different sets of tires front and back too, because of my afore mentioned issue, but it's not AS bad as having 2 different tires on the same axle.

Shitty ass used car dealer and shop (expect a write up of the shops very soon)

Well they are shit tires anyways probably the continental one is the only good one, but i'm getting winter tires soon, and new rims and summers tires, well in the summer.

I thought it would be better at the front, I noticed however after putting them up on the front,I am stopping better and not spinning my tires or screeching if i take a hard turn

Excuse this post, twas a mistake

For the same reason as pointed out by stevema188... if the front has better grip: when you need to suddenly brake and swerve you will find the front of the car stopping due to weight transfer onto the better tires, while the rear of the car breaks loose resulting in a skid or spinout. Or something simple as going around an off ramp the rear will kick out if you hit a wet patch.....

Would you put a running shoe on one foot and a sandal on the other and then try and run a marathon? If not why would you do it to your car! Tires are very important to the performance and feel of the vehicle.

Just to point out, the OP got the car that way.

I think we all agree that different tires are not the way to go. You want a matched set all the way around.

BTW: Car won't pass safety with mismatched tires........................... so if the car was safety-checked it had different tires on it at the time.......... there has to be some sort of law that would invalidate a safety check if material changes are made to the vehicle.

No, I understand he got the car like that. I'm just trying to stress the point that it's not right.
